==v0.1.0==&lt;br /&gt;
I&#039;d like to plan what functionality should be included in &#039;&#039;&#039;v0.1.0&#039;&#039;&#039; of the workbench, and when to cut the release.&lt;br /&gt;
&lt;br /&gt;
That way we have a stable release, and people don&#039;t use the workbench off of the &#039;&#039;&#039;master&#039;&#039;&#039; branch which is considered unstable and could have bugs or features that aren&#039;t fully functional.&lt;br /&gt;

&lt;br /&gt;
=Use Case=&lt;br /&gt;
We have a specific need for [[Summer X 2020]]. We will be building both the standard size version with 8&amp;quot; bed, and also a version with a 12&amp;quot; bed. We think that using the same 8 mm Universal Axis and 1/8&amp;quot;x1.5&amp;quot; angle frames and printed corners, we will be able to build fast (in terms of motion) printers up to about 16&amp;quot; print beds, and slower printers with up to about 24&amp;quot; print beds. Slower because there will be more vibration, so quality printing can be retained by moving slower. Slower motion does not reduce deposition rate as long as large nozzles (1.2 mm) are used - which have typical 25-50 mm/sec speeds. Thus, a larger 24&amp;quot; bed printer can still be built using the same materials as the [[D3D Pro]].&lt;br /&gt;
&lt;br /&gt;
To scale the 1/8&amp;quot;x1.5&amp;quot; to larger size - it is convenient to print out the frame corners at 200% size - without modification. In this case, 1/4&amp;quot;x3&amp;quot; angle can be used, and this is expected to produce up to 4&#039;x4&#039;x8&#039; tall printers using 3D printed corners - printers that are suitable for printing large construction panels using the [[Supervolcano Nozzle]] with deposition rate of 20 lb/day. We are also planning to build the 4x4x8 foot printer as such during [[Summer X 2020]] - which will be a simple 200% scale-up of the existing D3D frame parts. The actual axis to be used here will likely be a 1&amp;quot; universal axis.&lt;br /&gt;
&lt;br /&gt;
We have observed an advantage of using hollow shaft instead of 1&amp;quot; solid shaft for the 1&amp;quot; universal axis. We can use schedule 40 3/4&amp;quot; pipe for this purpose, which is close to 1&amp;quot; OD. It is not exactly 1&amp;quot;, so we must use custom linear bearings. This is doable using the [[3D Printed Linear Bushing]]. While this bushing is printable in PLA, we will work on printing bushings using Nylon or [[Acetal Filament]] using a high temperature print chamber. This is all planned for the first month of [[Summer X 2020]].&lt;br /&gt;

It&#039;s possible to remotely control LibreOffice via python using the python Uno bridge. See [https://forum.freecadweb.org/viewtopic.php?f=8&amp;amp;t=44005 How much interest is there to integrate LibreOffice into FreeCAD?] FreeCAD forum thread for more details.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{Hint|This is one of core OSE collaborative, open development protocols. You are welcome to improve this page by editing mercilessly.}}&lt;br /&gt;
&lt;br /&gt;
The key to successful management of large scale, global, open development collaboration - hardware or software - is [[Modular Breakdown]] of complex projects into small parts.&lt;br /&gt;
&lt;br /&gt;
For the case of hardware designs - modular breakdown means that we break machines and product systems down to their smallest components. &lt;br /&gt;
&lt;br /&gt;
Tracking any development effectively, and collaborating on a large scale - requires that each component is distinguished from the overall product - such that it can be developed independently and in parallel with many other components.&lt;br /&gt;
&lt;br /&gt;
Scalable parallel development can exist on the level of an overall product, its module, and its sub-modules or components.&lt;br /&gt;
&lt;br /&gt;
To document products and components, we use [[Part Libraries]]. Part libraries are also convenient in terms of how they can be modified using FreeCAD.&lt;br /&gt;
&#039;&#039;&#039;&lt;br /&gt;
A developer or user should be able to download parts and overall products from part libraries. To understand how part libraries relate to FreeCAD and large-scale parallel development - we must understand the Merge Workflow in FreeCAD:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
#FreeCAD has a Merge Workflow option. Go to File-&amp;gt;Merge project... to access this workflow.&lt;br /&gt;
#Proper use of this workflow allows files on the wiki - parts - to be merged into the same document.&lt;br /&gt;
#&#039;&#039;&#039;To use this workflow - files must be saved in a positionally correct location. This means, that when a second part it merged with a first part - it appears in a location like in the final product.&#039;&#039;&#039;&lt;br /&gt;
#One can start by downloading any single part, and merge new parts into the same working document as needed&lt;br /&gt;
#This way of handling parts allows full modular breakdown. Each file or part is accessible.&lt;br /&gt;
#Anyone can work on any part, and uplaod changes to the wiki on a granular basis. &lt;br /&gt;
#The wiki keeps old versions, so that we can work with older versions if needed at any time. The wiki thus has a full ability to do version history. It is useful to annotate older versions (either in file comments or on the wiki page for the versioned file) so other developers can see what the version contains.&lt;br /&gt;
#The main point of this is allowing many people to work in parallel on the same CAD design.&lt;br /&gt;
#Another advantage is retaining full versioning control on parts, not only on overall assembly.&lt;br /&gt;
#Another advantage is file size management: instead of uploading complete files, it takes much less disk space to upload only the changing parts. This becomes increasingly important with growing project size/complexity.&lt;br /&gt;
&lt;br /&gt;
The above summarizes how to work using the Merge Workflow. This can be used in conjuntion with more advanced workflows such as using the Asembly 2 Workbench. &lt;br /&gt;
&lt;br /&gt;
=More Notes on the Merge Workflow=&lt;br /&gt;
#It is useful to include a [[Visual Version History]] in the part library - which simply means pictures of snapshots of the file as it evolves in time. New snapshots are included for visual reference - to save time in assessing the content of files. This is an antidote to Git or other drop-box like platform - where a wall of filenames of parts takes time to parse for content. Git does not allow versioning at a granular level (new uploads over an existing individual files), only at a repository level. This does not work well for open hardware development because 2 component CAD files cannot be compared side by side.&lt;br /&gt;
#For solo work, it&#039;s acceptable to use git or other &#039;whole project versioning&#039; &lt;br /&gt;
#Note that &#039;whole project versioning&#039; at the level of CAD does not work well for large, collaborative open hardware, as CAD and software are only a small portion of an overall project. Thus, a wiki is still required to manage many other data formats while allowing for powerful organizational, taxonomy, or semantic organization aspects. &lt;br /&gt;
#The power of a wiki is the reason why OSE uses the wiki-based [[Development Template]], which is cloned in full for the next iteration. Parts of the Development Template are updated as needed, while keeping the whole project version intact.&lt;br /&gt;

Downloading the 64 bit .deb.&lt;br /&gt;
&lt;br /&gt;
I double clicked on it, and it opened up the TeighaFileConverter install in Ubuntu Software Center.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
It said:&lt;br /&gt;
&lt;br /&gt;
Lintian check results for /home/marcin/Desktop/TeighaFileConverter_QT5_lnxX64_4.7dll.deb:&lt;br /&gt;
E: TeighaFileConverter: bad-package-name&lt;br /&gt;

=Adding Downloaded Macros=&lt;br /&gt;
*To add a macro to FreeCAD - find the Macros directory by going to FreeCAD-&amp;gt;File-&amp;gt;Preferences-&amp;gt;Macros - which shows the macros directory such as /home/marcin/.FreeCAD&lt;br /&gt;
*Download a macro&lt;br /&gt;

&lt;div&gt;=FreeCAD Parametric Part Design and Drawing Workflow=&lt;br /&gt;
#Start with a spreadsheet in Spreadsheet view - define all parameters as numbers  (units optional) within individual cells&lt;br /&gt;
#Right click on each cell contining a variable value. Create an alias - this is FreeCAD&#039;s variable name.&lt;br /&gt;
#Create a part in part design view. Instead of entering values for constraints, click the little icon in the dimension box and associate each dimension with a variable name from the spreadsheet. With some careful forethought and planning, a fully parametric part may be produced in this manner.&lt;br /&gt;
#Enter Drawing view, create a new drawing, highlight the part and then &amp;quot;Insert an Orthographic Projection&amp;quot; of the part.  Each checkbox adds a different perspective of the part.&lt;br /&gt;
#Enter the Drawing Dimensioning view and click on the &amp;quot;Add Linear Dimension&amp;quot; icon. Click two points on one of the projections in order to draw the related dimensions on the Drawing.  The direction in which the dimensions are dragged before setting them with a click dictates whether x or y differences or oblique dimensions are displayed.&lt;br /&gt;
#Edit the drawing data in the &amp;quot;Editable&amp;quot; property box.&lt;br /&gt;
#Export the drawing as a pdf.&lt;br /&gt;

&lt;div&gt;{{Hint|This page shows how to install FreeCAD - legacy version 0.16 - for Ubuntu. OSE currently supports FreeCAD Legacy - but not later versions.}}&lt;br /&gt;
&lt;br /&gt;
=From FreeCAD Legacy Search=&lt;br /&gt;
&lt;br /&gt;
https://launchpad.net/~freecad-maintainers/+archive/ubuntu/freecad-legacy&lt;br /&gt;
&lt;br /&gt;
=Install Attempt=&lt;br /&gt;
Here is the result of the installation after the autoremove - &lt;br /&gt;
&lt;br /&gt;
Doesn&#039;t look like it worked, unless it will work after I restart. Any suggestions for how to make it install?&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Response from Abe:&lt;br /&gt;
&lt;br /&gt;
I think the line with Hit:27 implies it is installed. My update has a few errors that don&#039;t effect anything else and in my experience, it will specify if something is blocking updates/installs.&lt;br /&gt;
&lt;br /&gt;
Have you tried a system search via the Ubuntu menu? The icons showed up there for me after install and I dragged them to the bar.&lt;br /&gt;
&lt;br /&gt;
I&#039;m not sure its needed but you can clean the repositories list. The &amp;quot;apt clean&amp;quot; command cleans the apt cache and I&#039;m not sure exactly what the consequences of that is, but I see no issues after.&lt;br /&gt;
&lt;br /&gt;
https://itsfoss.com/how-to-remove-or-delete-ppas-quick-tip/&lt;br /&gt;
&lt;br /&gt;
https://www.maketecheasier.com/8-ways-to-maintain-a-clean-lean-ubuntu-machine/&lt;br /&gt;
&lt;br /&gt;
=Do You Have It?=&lt;br /&gt;
&lt;br /&gt;
In terminal try: apt list | grep freecad-0.16&lt;br /&gt;
If it is listed then entering freecad-0.16 should run version 0.16, I think the icon showed up after install, but maybe I had to it some other way. Or maybe it will create it after running it once from the terminal.&lt;br /&gt;
&lt;br /&gt;
[[File:doyouhaveit.png]]&lt;br /&gt;
&lt;br /&gt;
=Install=&lt;br /&gt;
Actually, mine says freecad-0.16/xenial,now 1:0.16.6712-0ppa6~ubuntu16.04.1 amd64 [installed]&lt;br /&gt;
&lt;br /&gt;
Oh, I confused the two different ubuntu package apps apt and apt-get, which might matter because the freecad PPA web page commands are add-apt &amp;amp; apt-get. Although I&#039;d guess they both work on the same file lists. &lt;br /&gt;
https://itsfoss.com/apt-vs-apt-get-difference/&lt;br /&gt;
&lt;br /&gt;
So try:&lt;br /&gt;
&lt;br /&gt;
sudo apt-get install freecad-0.16&lt;br /&gt;
&lt;br /&gt;
Or to clean try:&lt;br /&gt;
&lt;br /&gt;
sudo apt-get autoremove&lt;br /&gt;
&lt;br /&gt;
sudo apt-get autoclean&lt;br /&gt;
&lt;br /&gt;
*Easy Installation via Terminal using apt &amp;lt;pre&amp;gt;CTRL+ALT+T&amp;lt;/pre&amp;gt; &amp;lt;pre&amp;gt;sudo apt install freecad-0.16﻿&amp;lt;/pre&amp;gt;&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;=2018-09 Review=&lt;br /&gt;
&lt;br /&gt;
In 2018-09, I ([[User:Maltfield|Michael Altfield]]) had just learned about Discourse as I was working on the [[phplist]] project. [https://discuss.phplist.com phplist&#039;s forums] use Discourse. At the same time, [[User:Alexau|Alex Au]] recommended to Marcin that we setup a [[CHG-2018-02-04|replacement forum]] using Discourse.&lt;br /&gt;
&lt;br /&gt;
==Pros==&lt;br /&gt;
&lt;br /&gt;
# Very pleasant interface&lt;br /&gt;
# Very nice functionality ootb. Badges, user trust system for easy moderation, climbing ranks, love, at-calls (@), etc -- co-founder Jeff Atwood also founded Stack Exchange, so expect similar functionality&lt;br /&gt;
# Very popular. Many, many forums have switched to Discourse over the past several years&lt;br /&gt;
# Great selection of plugins &amp;amp; integrations (though no decent db/index for searching them) https://meta.discourse.org/c/plugin https://github.com/discourse&lt;br /&gt;
## ie: replace wordpress comments with a discourse thread. This may or may not be good.&lt;br /&gt;
### Example wordpress blog post: https://blog.discourse.org/2018/06/understanding-discourse-trust-levels/&lt;br /&gt;
### Corresponding discourse thread for the comments to the above post: https://meta.discourse.org/t/wp-discourse-dysfunctional-shows-only-start-the-discussion-at/36016&lt;br /&gt;
# Looks like we can import our content from Vanila https://meta.discourse.org/t/how-to-migrate-from-vanilla-to-discourse/27273&lt;br /&gt;
# Well-funded org that hosts their project (think wordpress.com) for many of their customers. The good here is that Discorse can pay a salary to devs, unlike many open source projects. But it&#039;s worth nothing that people choose to pay for hosting probably because it&#039;s Ruby on Rails, and a PIA to self-host.&lt;br /&gt;
# While not officially supported, it looks like users have setup Discourse behind varnish 4 &amp;lt;ref&amp;gt;https://meta.discourse.org/t/discourse-behind-varnish/4864/10&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Cons==&lt;br /&gt;
&lt;br /&gt;
# Ruby on rails&lt;br /&gt;
# They openly state that they&#039;re hard to install, and therefore _only_ support installation via a docker container &amp;lt;ref&amp;gt;https://github.com/discourse/discourse/blob/master/docs/INSTALL.md#why-do-you-only-officially-support-docker&amp;lt;/ref&amp;gt;&lt;br /&gt;
# I&#039;m seriously worried about the security of a project that thinks it&#039;s acceptable to use &amp;lt;code&amp;gt;wget -qO- https://get.docker.com/ | sh&amp;lt;/code&amp;gt; as a step in their install guide &amp;lt;ref&amp;gt;https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md#install-docker--git&amp;lt;/ref&amp;gt;&lt;br /&gt;
# Discourse explicitly states that they only support newer devices. I&#039;m concerned that means that we may make our content inaccessible to, say, that 6-year-old desktop running windows xp in the machine shop. Indeed, discourse only supports IE 11+, which came with Windows 8.1 in 2013--5 years ago. &amp;lt;ref&amp;gt;https://github.com/discourse/discourse#requirements&amp;lt;/ref&amp;gt;&lt;br /&gt;
# If javascript is disabled, the site is read-only. JS is a requirement for posting, replying, etc. But because Discourse also functions as a mailing list, JS-free users can still contribute content in a limited way by replying to threads via email &amp;lt;ref&amp;gt;https://forums.whonix.org/t/turn-off-javascript-for-forums/1692/2&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Neutral==&lt;br /&gt;
# Project has been around for 5 years (initial release in 2013) https://en.wikipedia.org/wiki/Discourse_%28software%29&lt;br /&gt;

&lt;br /&gt;
==Action Plan==&lt;br /&gt;
&lt;br /&gt;
* Recruit software developer to analyze FreeCAD and build with/upon their work. Short-term Objective: Get Assembly Module Working.&lt;br /&gt;
* Document FreeCAD source code in github repository.&lt;br /&gt;
* Document FreeCAD&#039;s code structure. (some preliminary work available at https://github.com/qingfengxia/FreeCAD_Mod_Dev_Guide)&lt;br /&gt;

=OSE FreeCAD Documentation=&lt;br /&gt;
&lt;br /&gt;
I (Mark Norton) have created a very simply, introductory guide to FreeCAD.  It only covers the very basics at this point, but we can expand on it as needed.  -  [[User:Mjn]]&lt;br /&gt;
&lt;br /&gt;
[[File:FreeCAD-3.pdf]]&lt;br /&gt;
&lt;br /&gt;
This document covers the following topics:&lt;br /&gt;
&lt;br /&gt;
* Views&lt;br /&gt;
* Workshops&lt;br /&gt;
* Sizing a Primitive Part&lt;br /&gt;
* Positioning a Part&lt;br /&gt;
* Making a Cut&lt;br /&gt;
* Combining Parts&lt;br /&gt;
* Rotating a Part&lt;br /&gt;
* Extrusion&lt;br /&gt;
&lt;br /&gt;
See also, FreeCAD Documentation and Tutorials [http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Main_Page].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=OSE FreeCAD Requirements=&lt;br /&gt;
For OSE to use FreeCAD for all of its design needs, these are the functions required. Do these exist? Please comment.&lt;br /&gt;
&lt;br /&gt;
*Freehand drawing of shapes and extrusion (like Sketchup).[[Image:check.png]]&lt;br /&gt;
*Adding parameters to all of the shapes, so they can be modified. [[Image:check.png]]&lt;br /&gt;
*Modifying all parameters in 3D parametrically (typing in lengths) [[Image:check.png]]&lt;br /&gt;
*Modifying all parameters in 3D with the mouse (such as dragging corners, edges, and faces)&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;This is not possible and will not be in the future. This kind of behavior needs quite advanced back-end functionality which is not provided by our geometric modeling kernel&amp;quot;&lt;br /&gt;
&lt;br /&gt;
*Adding parameters in 3D parametrically (boolean operations)? [[Image:check.png]]&lt;br /&gt;
*Adding parameters in 3D by drawing them and extruding (mouse-based boolean operations)&lt;br /&gt;
*Adding parameters to shapes in 3D parametrically (such as drawing in new objects parametrically)?&lt;br /&gt;
*Adding parameters to shapes in 3D manually (such as drawing in new objects with a mounse)?&lt;br /&gt;
*For multiple objects, moving them with the mouse to arrange, mate, align them.&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;That is not yet possible. The assembly workbench is in a very early design phase and still needs quite some time. That is true for basic functionality and integration into freecad workflows.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
*Grouping and ungrouping objects into assemblies?&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;not yet but will be possible with upcoming assembly workbench&amp;quot;&lt;br /&gt;
&lt;br /&gt;
*Maintaining parametric nature of grouped objects?&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;not yet, but will be possible with the upcoming assembly workbench&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Now for interoperability with other CAD packages:&lt;br /&gt;
&lt;br /&gt;
*Importing multiple new objects into a drawing - one at a time?&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &#039;currently you can only import whole files, not individual objects from a file&#039;&lt;br /&gt;
&lt;br /&gt;
*Importing multiple objects into a model - all at one time? [[Image:check.png]]&lt;br /&gt;
*Importing new objects while passing the parametric values into FreeCAD, such as with a STEP file?&lt;br /&gt;

=Contributors and Users=&lt;br /&gt;
From Kostas:&lt;br /&gt;
*Jürgen Riegel is the project founder, working for Daimler Chrysler, his free time is probably limited https://sourceforge.net/apps/mediawiki/free-cad/index.php?title=User:Jriegel &#039;&#039;Update: Jurgen has not been active on the project for many years now. [[User:Kunda|Kunda]] ([[User talk:Kunda|talk]]) 13:46, 4 August 2018 (UTC)&#039;&#039;&lt;br /&gt;
*Werner Mayer is the most active developer in terms of commits, he is just awesome, I don&#039;t know what he does professionally but if some funding can get him to increase the time of his participation, this would definitely be a great investment of financial resources. &lt;br /&gt;
*Yorik is our architect: http://yorik.uncreated.net and he is already dedicating a lot of hours in the development of FreeCAD, since he is a free lancer he is probably quite flexible with time, so maybe he could implement special feature requests for FreeCAD even on a paid basis. FYI [https://www.patreon.com/yorikvanhavre Yorik van Havre] has a Patreon account.&lt;br /&gt;
*j-dowset, joined FreeCAD recently and has done a great work on improving blueprints creation in FreeCAD. A very appropriate task for him would be to implement a correct dimensioning system for blueprints. I believe he has the capabilities to implement any kind of feature with relatively short running in time and high quality. &#039;&#039;Update: User is dormant [[User:Kunda|Kunda]] ([[User talk:Kunda|talk]]) 13:46, 4 August 2018 (UTC)&lt;br /&gt;
&#039;&#039;*mrlukeparry is quite experienced with Qt and Coin3D so he can do a lot of GUI work. Being a student his free time is probably also limited except school vacations. &#039;&#039;Update: he left and returned but hasn&#039;t been active at all in the code or community [[User:Kunda|Kunda]] ([[User talk:Kunda|talk]]) 13:46, 4 August 2018 (UTC)&#039;&#039;&lt;br /&gt;
*Ickby has worked on a prototype for applying assembly constraints between parts. A special task for him would be to accelerate the implementation of the Assembly module after jriegel has finished with the basic framework/structure/design. &#039;&#039;Update: Ickby has not been very low key for some time. He participates in the forums but has not contributed to the code in a long time, at least not publically. This may change. [[User:Kunda|Kunda]] ([[User talk:Kunda|talk]]) 13:46, 4 August 2018 (UTC)&#039;&#039;&lt;br /&gt;
*tanderson69 is very good in OpenCascade, so he can work on difficult tasks that have to do with the CAD geometry kernel. &#039;&#039;Update: Participates on the forum and very sporadically on the code. I believe he is involved in another project.&#039;&#039;&lt;br /&gt;

==Action Plan==&lt;br /&gt;
&lt;br /&gt;
* Recruit software developer to analyze FreeCAD and build with/upon their work. Short-term Objective: Get Assembly Module Working.&lt;br /&gt;
* Document FreeCAD source code in github repository.&lt;br /&gt;
* Document FreeCAD&#039;s code structure. (some preliminary work available at https://github.com/qingfengxia/FreeCAD_Mod_Dev_Guide)&lt;br /&gt;

I (Mark Norton) have created a very simply, introductory guide to FreeCAD.  It only covers the very basics at this point, but we can expand on it as needed.  -  [[User:Mjn]]&lt;br /&gt;
&lt;br /&gt;
[[File:FreeCAD-3.pdf]]&lt;br /&gt;
&lt;br /&gt;
This document covers the following topics:&lt;br /&gt;
&lt;br /&gt;
* Views&lt;br /&gt;
* Workshops&lt;br /&gt;
* Sizing a Primitive Part&lt;br /&gt;
* Positioning a Part&lt;br /&gt;
* Making a Cut&lt;br /&gt;
* Combining Parts&lt;br /&gt;
* Rotating a Part&lt;br /&gt;
* Extrusion&lt;br /&gt;

=OSE FreeCAD Requirements=&lt;br /&gt;
For OSE to use FreeCAD for all of its design needs, these are the functions required. Do these exist? Please comment.&lt;br /&gt;
&lt;br /&gt;
*Freehand drawing of shapes and extrusion (like Sketchup).[[Image:check.png]]&lt;br /&gt;
*Adding parameters to all of the shapes, so they can be modified. [[Image:check.png]]&lt;br /&gt;
*Modifying all parameters in 3D parametrically (typing in lengths) [[Image:check.png]]&lt;br /&gt;
*Modifying all parameters in 3D with the mouse (such as dragging corners, edges, and faces)&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;This is not possible and will not be in the future. This kind of behavior needs quite advanced back-end functionality which is not provided by our geometric modeling kernel&amp;quot;&lt;br /&gt;
&lt;br /&gt;
*Adding parameters in 3D parametrically (boolean operations)? [[Image:check.png]]&lt;br /&gt;
*Adding parameters in 3D by drawing them and extruding (mouse-based boolean operations)&lt;br /&gt;
*Adding parameters to shapes in 3D parametrically (such as drawing in new objects parametrically)?&lt;br /&gt;
*Adding parameters to shapes in 3D manually (such as drawing in new objects with a mounse)?&lt;br /&gt;
*For multiple objects, moving them with the mouse to arrange, mate, align them.&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;That is not yet possible. The assembly workbench is in a very early design phase and still needs quite some time. That is true for basic functionality and integration into freecad workflows.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
*Grouping and ungrouping objects into assemblies?&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;not yet but will be possible with upcoming assembly workbench&amp;quot;&lt;br /&gt;
&lt;br /&gt;
*Maintaining parametric nature of grouped objects?&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;not yet, but will be possible with the upcoming assembly workbench&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Now for interoperability with other CAD packages:&lt;br /&gt;
&lt;br /&gt;
*Importing multiple new objects into a drawing - one at a time?&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &#039;currently you can only import whole files, not individual objects from a file&#039;&lt;br /&gt;
&lt;br /&gt;
*Importing multiple objects into a model - all at one time? [[Image:check.png]]&lt;br /&gt;
*Importing new objects while passing the parametric values into FreeCAD, such as with a STEP file?&lt;br /&gt;

=Contributors and Users=&lt;br /&gt;
From Kostas:&lt;br /&gt;
*Jürgen Riegel is the project founder, working for Daimler Chrysler, his free time is probably limited https://sourceforge.net/apps/mediawiki/free-cad/index.php?title=User:Jriegel&lt;br /&gt;
*Werner Mayer is the most active developer in terms of commits, he is just awesome, I don&#039;t know what he does professionally but if some funding can get him to increase the time of his participation, this would definitely be a great investment of financial resources.&lt;br /&gt;
*Yorik is our architect: http://yorik.uncreated.net and he is already dedicating a lot of hours in the development of FreeCAD, since he is a free lancer he is probably quite flexible with time, so maybe he could implement special feature requests for FreeCAD even on a paid basis. FYI [https://www.patreon.com/yorikvanhavre Yorik van Havre] has a Patreon account.&lt;br /&gt;
*j-dowset, joined FreeCAD recently and has done a great work on improving blueprints creation in FreeCAD. A very appropriate task for him would be to implement a correct dimensioning system for blueprints. I believe he has the capabilities to implement any kind of feature with relatively short running in time and high quality.&lt;br /&gt;
*mrlukeparry is quite experienced with Qt and Coin3D so he can do a lot of GUI work. Being a student his free time is probably also limited except school vacations.&lt;br /&gt;
*Ickby has worked on a prototype for applying assembly constraints between parts. A special task for him would be to accelerate the implementation of the Assembly module after jriegel has finished with the basic framework/structure/design.&lt;br /&gt;
*tanderson69 is very good in OpenCascade, so he can work on difficult tasks that have to do with the CAD geometry kernel.&lt;br /&gt;
*Daniel Falck is the person to contact for CAM integration.&lt;br /&gt;

* A room in which users experience wet or dry heat (More ofter the latter)&lt;br /&gt;
* Is traditionally Finnish, but has diffused outward&lt;br /&gt;
* Uses gas or electric heat&lt;br /&gt;
* Feels nice especially when user has muscle aches/pain/soreness, as the heat eases these&lt;br /&gt;
* Is more of a luxury item, but adds to the comfort and health of a population&lt;br /&gt;

&lt;br /&gt;
==Strategy==&lt;br /&gt;
Collaborate with open source support institutes such as [[INRIA]] to develop FreeCAD to open source product development standards.&lt;br /&gt;

&lt;br /&gt;
==Action Plan==&lt;br /&gt;
&lt;br /&gt;
* Recruit software developer to analyze FreeCAD and build with/upon their work. Short-term Objective: Get Assembly Module Working.&lt;br /&gt;
* Document FreeCAD source code in github repository.&lt;br /&gt;
* Document FreeCAD&#039;s code structure. (some preliminary work available at https://github.com/qingfengxia/FreeCAD_Mod_Dev_Guide)&lt;br /&gt;

[[File:FreeCAD-3.pdf]]&lt;br /&gt;
&lt;br /&gt;
This document covers the following topics:&lt;br /&gt;
&lt;br /&gt;
* Views&lt;br /&gt;
* Workshops&lt;br /&gt;
* Sizing a Primitive Part&lt;br /&gt;
* Positioning a Part&lt;br /&gt;
* Making a Cut&lt;br /&gt;
* Combining Parts&lt;br /&gt;
* Rotating a Part&lt;br /&gt;
* Extrusion&lt;br /&gt;

=OSE FreeCAD Requirements=&lt;br /&gt;
For OSE to use FreeCAD for all of its design needs, these are the functions required. Do these exist? Please comment.&lt;br /&gt;
&lt;br /&gt;
*Freehand drawing of shapes and extrusion (like Sketchup).[[Image:check.png]]&lt;br /&gt;
*Adding parameters to all of the shapes, so they can be modified. [[Image:check.png]]&lt;br /&gt;
*Modifying all parameters in 3D parametrically (typing in lengths) [[Image:check.png]]&lt;br /&gt;
*Modifying all parameters in 3D with the mouse (such as dragging corners, edges, and faces)&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;This is not possible and will not be in the future. This kind of behavior needs quite advanced back-end functionality which is not provided by our geometric modeling kernel&amp;quot;&lt;br /&gt;
&lt;br /&gt;
*Adding parameters in 3D parametrically (boolean operations)? [[Image:check.png]]&lt;br /&gt;
*Adding parameters in 3D by drawing them and extruding (mouse-based boolean operations)&lt;br /&gt;
*Adding parameters to shapes in 3D parametrically (such as drawing in new objects parametrically)?&lt;br /&gt;
*Adding parameters to shapes in 3D manually (such as drawing in new objects with a mounse)?&lt;br /&gt;
*For multiple objects, moving them with the mouse to arrange, mate, align them.&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;That is not yet possible. The assembly workbench is in a very early design phase and still needs quite some time. That is true for basic functionality and integration into freecad workflows.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
*Grouping and ungrouping objects into assemblies?&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;not yet but will be possible with upcoming assembly workbench&amp;quot;&lt;br /&gt;
&lt;br /&gt;
*Maintaining parametric nature of grouped objects?&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &amp;quot;not yet, but will be possible with the upcoming assembly workbench&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Now for interoperability with other CAD packages:&lt;br /&gt;
&lt;br /&gt;
*Importing multiple new objects into a drawing - one at a time?&lt;br /&gt;
&lt;br /&gt;
[https://github.com/ickby Response from FreeCAD developer ickby]: &#039;currently you can only import whole files, not individual objects from a file&#039;&lt;br /&gt;
&lt;br /&gt;
*Importing multiple objects into a model - all at one time? [[Image:check.png]]&lt;br /&gt;
*Importing new objects while passing the parametric values into FreeCAD, such as with a STEP file?&lt;br /&gt;

=Contributors and Users=&lt;br /&gt;
From Kostas:&lt;br /&gt;
*Jürgen Riegel is the project founder, working for Daimler Chrysler, his free time is probably limited https://sourceforge.net/apps/mediawiki/free-cad/index.php?title=User:Jriegel&lt;br /&gt;
*Werner Mayer is the most active developer in terms of commits, he is just awesome, I don&#039;t know what he does professionally but if some funding can get him to increase the time of his participation, this would definitely be a great investment of financial resources.&lt;br /&gt;
*Yorik is our architect: http://yorik.uncreated.net and he is already dedicating a lot of hours in the development of FreeCAD, since he is a free lancer he is probably quite flexible with time, so maybe he could implement special feature requests for FreeCAD even on a paid basis. FYI [https://www.patreon.com/yorikvanhavre Yorik van Havre] has a Patreon account.&lt;br /&gt;
*j-dowset, joined FreeCAD recently and has done a great work on improving blueprints creation in FreeCAD. A very appropriate task for him would be to implement a correct dimensioning system for blueprints. I believe he has the capabilities to implement any kind of feature with relatively short running in time and high quality.&lt;br /&gt;
*mrlukeparry is quite experienced with Qt and Coin3D so he can do a lot of GUI work. Being a student his free time is probably also limited except school vacations.&lt;br /&gt;
*Ickby has worked on a prototype for applying assembly constraints between parts. A special task for him would be to accelerate the implementation of the Assembly module after jriegel has finished with the basic framework/structure/design.&lt;br /&gt;
*tanderson69 is very good in OpenCascade, so he can work on difficult tasks that have to do with the CAD geometry kernel.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;=Introduction=&lt;br /&gt;
Read this informative article by open hardware advocate Bunnie Huang - on how to make a proper Bill of Materials - http://www.bunniestudios.com/blog/?page_id=2812&lt;br /&gt;
&lt;br /&gt;
=General Protocol - OSE International=&lt;br /&gt;
Search the web for suppliers serving the area.of interest. For the seminal workshop, this is the Maysville, MO area in the USA, zip code 64469.&lt;br /&gt;
&lt;br /&gt;
Suppliers can include local Hardware stores, such as menards, home depot, and Lowes as the main ones in the area. [[Mokan Fastener]] is the most favorable local industrial supply of bolts. [[Metal by the Foot]] is a local contractor supploer of all steel sections, up to 3&amp;quot; diameter rod or larger. There will be other industrial suppliers, [[McMaster-Carr]] being the most favorable, followed by [[Grainger]] and [[Misumi]] that specializes in cut to length aluminum extrusions. Locally there is the [[Sweiger Shop]] as a heavy metal fabricator. Then there are various global online stores. Amazon and ebay are common sources. And ultimately, there is Alibaba and China, which has many [[OEM]] sources, where one needs to email and get a quote. Sometimes these OEMs will have a formal [[RFQ]] forms, or less formal email. Relevant considerations there are lead time needed, as well as Minimum Order Quantity ([[MOQ]]).&lt;br /&gt;
&lt;br /&gt;
In order to promote open-sourcing of the supply chain, we can collaborate with other open source enterprises and request that they share their supply chain information with the world. Our allies may include entities like Lulzbot, Prusa Research, Folgertech 3D Printers, Andrew Graham, who is currently developing a kit, Chris Palmer who has sold kits before, Adrian Bowyer who started the open source 3D printer movement, Ultimaker, and Zach Hoeken, one of the original creators of Makerbots - along with OSHWA, Sparkfun, Adafruit, and others.&lt;br /&gt;
&lt;br /&gt;
Further we can also invite those entities who typically do not share their IP, such as Stratasys and other proprietary vendors, [[OEM]]s, and suppliers.&lt;br /&gt;
&lt;br /&gt;
The critical aspect of supply chain management is to perform an exhaustive search of sources. This process should be adapted to various locations around the world - such as a producer in the USA may naturally have a different metal supplier than an Indian producer. Thus, this template should be localized for any OSE branch. An existing Template may be used as the starting point.&lt;br /&gt;
&lt;br /&gt;
The IP value of the open source supply chain is that the supply chain listing should distinguish between reliable and unreliable sources - on grounds of product quality, shipping, service, or other factors. The difference between a good supplier and bad support can mean heavy losses, or even going out of business. Supply chain risk is perhaps the most u controllable risk in distributed production, for which reason OSE&#039;s ultimate approach to solve this issue at the core is [[Technological Recursion]] and [[Import Substitution]] via relocalized production and supply chain creation within minimum distance practical, which should be no more than one hour travel distance. This facilitates not only a Robust supply chain, but also rapid innovation cycles within OSE&#039;s framework as a learning organization striving for continuous improvement.&lt;br /&gt;
&lt;br /&gt;
The template below shows space for 5 suppliers, which should reflect convergence to the best supplier (in cost, time, quality, reliability), especially in that supplier prices can be compared to OEM prices. Research from trusted references or product revuews can help determine the actual product quality. &lt;br /&gt;
&lt;br /&gt;
The critical skill in creating a good BOM is determined when the search has been exhaustive, and the best decision has been made. To make this decision, references, reviews, or recurrence of a similar price for apparently the same features - are the best guide. Since the supply chain can change dynamically, reliability and start ility is important. The first choice of verifying suppliers would be word of mouth or referral from other customers, especially trusted customers.&lt;br /&gt;
&lt;br /&gt;
=Local Adaptation=&lt;br /&gt;
Just like we create sourcing for the original OSE International location - sourcing should be locally adapted for most favorable sources for build locations other than Missouri, USA. Thus, there should be a whole set of BOM spreadsheets available - for local adaptation.&lt;br /&gt;
&lt;br /&gt;
=Template=&lt;br /&gt;
Notes: To calculate weight of steel plate, use [[Metals Weight Calculator]], [[Steel Plate Weight Calculator]] (includes holes), or fpr bolts, use [[Bolt Weight Calculator]].&lt;br /&gt;

&lt;div&gt;=Simplified Protocol for a Spreadsheet=&lt;br /&gt;
The critical parts of a BOM are:&lt;br /&gt;
*quantity of part&lt;br /&gt;
*Part description&lt;br /&gt;
*Link to part&lt;br /&gt;
*cost of parts&lt;br /&gt;
*total cost &lt;br /&gt;
&lt;br /&gt;
See example of this at [[Power_Cube_v17.08#BOM]], click edit, and make a copy of this to make your own BOM.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Simplified Protocol for a Visual BOM=&lt;br /&gt;
See example of a visual parts list:&lt;br /&gt;
*This is done with Google Slides, making a table, adding links,and adding images cut and pasted from FreeCAD or from suppliers&#039; websites.&lt;br /&gt;

&lt;br /&gt;
=Full Protocol=&lt;br /&gt;
&lt;br /&gt;
A complete Bill of Materials (BOM) specifies parts/materials/resources needed for a build, and specifies where/how to get them. A formal BOM should include the following for each specified purchase item:&lt;br /&gt;
&lt;br /&gt;
#Item Number&lt;br /&gt;
#Quantity&lt;br /&gt;
#Item description. Write down unique identifying properties.&lt;br /&gt;
#Link - direct link that takes one to arrive at description, source, and price (whenever available)&lt;br /&gt;
#AVL - Approved Vendor List - this defines what vendor the item can be purchased from. If a specific Link is provided above, the AVL must also be filled out. This specifies what may be substituted. If it doesn&#039;t matter, write Open/Any. If a specific manufacturer is required, write down that specific manufacturer or distributor. The AVL may also be specified in the negative, such as - do not buy from Manufacturer X.&lt;br /&gt;
#AVL PN - Approved Vendor List Part Number - specify the manufacturer&#039;s or distributor&#039;s part number whenever possible.&lt;br /&gt;
#MOQ - Specify the Minimum Order Quantity&lt;br /&gt;
#Lead Time - time to doorstep - or required from the placement or order to arrival of product at your doorstep. If shipping is not included, specify instructions for how to ship/pick up/deliver the item.&lt;br /&gt;
#Price. Critical element for assessing cost to performance ratios of desired products.&lt;br /&gt;
#Substitution Notes. A description of what other parts would work - based on general properties, characteristics, criteria, or design rationales being made explicit.&lt;br /&gt;
#Other Geographic Sources. Additional entries, corresponding to other geographical locations, may be added on other sheets of the spreadsheet, with the same Item Number. For example, for sources of parts in Chile, a different list of suppliers may be used.&lt;br /&gt;
&lt;br /&gt;
=Quality Assessment=&lt;br /&gt;
To assess the quality of a BOM:&lt;br /&gt;
*A BOM is deemed proper when all parts are explicit and unambiguous, where a link is provided to a purchase source. In absence of a link, a supplier phone number or contact information is sufficient.&lt;br /&gt;
*Given that a stable supply chain is a common risk in manufacturing, Substitution Notes are a useful feature that would allow a builder to reason what is acceptable as a substitute, and what isn&#039;t.&lt;br /&gt;
&lt;br /&gt;
=HowTo=&lt;br /&gt;
#Create a Google Doc spreadsheet for your BOM - use this [[BOM Template]]. Make sure you have included as many of the BOM items in the Introduction above as possible.&lt;br /&gt;
##To create a Google Doc from the [[BOM Template]], click the Edit link below the spreadsheet. You will be taken to the actual template.&lt;br /&gt;
##Go to File-&amp;gt;Make a copy... and make a copy of the template.&lt;br /&gt;
##To embed the Google Doc in a wiki page, see [[Embedding Google Docs in the Wiki]].&lt;br /&gt;
#If you do not use Google Docs, just use the wiki and create a page with the BOM that includes the spreadsheet by using wiki markup.&lt;br /&gt;
#Embed your google doc in a wiki page of your choice. Name the wiki page _______(module) BOM.&lt;br /&gt;
#Embed an [[Editing Link]] to your Google Doc below the Google Doc on that wiki page.&lt;br /&gt;

&lt;div&gt;=Simplified Protocol for a Spreadsheet=&lt;br /&gt;
The critical parts of a BOM are:&lt;br /&gt;
*quantity of part&lt;br /&gt;
*Part description&lt;br /&gt;
*Link to part&lt;br /&gt;
*cost of parts&lt;br /&gt;
*total cost &lt;br /&gt;
&lt;br /&gt;
See example of this at [[Power_Cube_v17.08#BOM]], click edit, and make a copy of this to make your own BOM.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Simplified Protocol for a Visual BOM=&lt;br /&gt;
See example of a visual parts list:&lt;br /&gt;
*This is done with Google Slides, making a table, adding links,and adding images cut and pasted from FreeCAD or from suppliers&#039; websites.&lt;br /&gt;

&lt;br /&gt;
=Full Protocol=&lt;br /&gt;
&lt;br /&gt;
A complete Bill of Materials (BOM) specifies parts/materials/resources needed for a build, and specifies where/how to get them. A formal BOM should include the following for each specified purchase item:&lt;br /&gt;
&lt;br /&gt;
#Item Number&lt;br /&gt;
#Quantity&lt;br /&gt;
#Item description. Write down unique identifying properties.&lt;br /&gt;
#Link - direct link that takes one to arrive at description, source, and price (whenever available)&lt;br /&gt;
#AVL - Approved Vendor List - this defines what vendor the item can be purchased from. If a specific Link is provided above, the AVL must also be filled out. This specifies what may be substituted. If it doesn&#039;t matter, write Open/Any. If a specific manufacturer is required, write down that specific manufacturer or distributor. The AVL may also be specified in the negative, such as - do not buy from Manufacturer X.&lt;br /&gt;
#AVL PN - Approved Vendor List Part Number - specify the manufacturer&#039;s or distributor&#039;s part number whenever possible.&lt;br /&gt;
#MOQ - Specify the Minimum Order Quantity&lt;br /&gt;
#Lead Time - time to doorstep - or required from the placement or order to arrival of product at your doorstep. If shipping is not included, specify instructions for how to ship/pick up/deliver the item.&lt;br /&gt;
#Price. Critical element for assessing cost to performance ratios of desired products.&lt;br /&gt;
#Substitution Notes. A description of what other parts would work - based on general properties, characteristics, criteria, or design rationales being made explicit.&lt;br /&gt;
#Other Geographic Sources. Additional entries, corresponding to other geographical locations, may be added on other sheets of the spreadsheet, with the same Item Number. For example, for sources of parts in Chile, a different list of suppliers may be used.&lt;br /&gt;

&lt;div&gt;OpenFOAM is a open source computational fluid dynamics software, this may be a bit unnecessary at this time, but i thought i would just bring it up for future reference.&lt;br /&gt;
&lt;br /&gt;
Here is a link to their website:&lt;br /&gt;

https://www.openfoam.com&lt;br /&gt;
&lt;br /&gt;
FYI FreeCAD 0.17 has OpenFOAM capability. See https://forum.freecadweb.org/viewtopic.php?style=4&amp;amp;f=18&amp;amp;t=21576&lt;/div&gt;</summary>

&lt;div&gt;== Intro ==&lt;br /&gt;
OSE integrates [[FreeCAD]] in to it&#039;s workflow very profoundly so it makes sense that there be an open collaboration between the 2 projects. This wiki page has been established to help the 2 projects inform each other. &lt;br /&gt;
&lt;br /&gt;
=== Points ===&lt;br /&gt;
* Currently as of this writing, OSE only uses FreeCAD v0.16 stable. This makes sense so that all OSE devs are on the same page and there is no potential backward compatibility conflict. The problem is that many fixes and features have been added since then in FreeCAD v0.17dev &lt;br /&gt;
* FreeCAD has a very powerful python scripting engine. It doesn&#039;t seem that it&#039;s being fully utilized by OSE.&lt;br /&gt;
* There doesn&#039;t seem to be much open communication between OSE and FC communities. &lt;br /&gt;
* FC 0.17dev has introduced more robust Workbenches like PATH and FEM that could be very very cost-effective and helpful for planning/executing OSE projects better.&lt;br /&gt;
* OSE could attract more devs to improve FC and vice-a-versa&lt;br /&gt;
* FC has an ever growing robust [https://github.com/FreeCAD/FreeCAD-addons Addon ecosystem]. Tools like Nurbs, Silk, Flamingo Pype tools etc... could be very useful for OSE. &lt;br /&gt;

&lt;br /&gt;
In order to make the Power Cube much more accessible, we can use a smaller engine - 18 hp - which is approximately 1/3 the effective cost of a 27 HP engine. This would allow us to make smaller machines possible, such as an 18hp walk-behind tractor. The lower cost of the 18hp option allows for wider replicability, and may allow operation without a hydraulic cooler in some applications - reducing cost and complexity significantly. Several major improvements include:&lt;br /&gt;
*Design for stable operation with biomass charcoal pellets to move in the direction of renewable energy biofuels that are 10x as efficient as liquid biofuels to produce&lt;br /&gt;
*Design for modularity - allowing for interchangeable hydraulic pumps. To date, we have not been using design-for-interchange (completely modular hydraulic pumps) due to the complexity of pump-to-motor coupling. By creating a smart coupling interface, hydraulic pump modularity is feasible, and is the next logical step. This would allow use of the Power Cube&lt;br /&gt;
*Simplified frame CNC cut from metal sheet, as opposed to angle, as developed for [[D3D]] and as was discovered is easier to fabricate. With 13 IPM [[Welding Travel Speed]] - a frame can be laid up quickly and welded 24&amp;quot;, 12 sides - in 1/2 hour. That is quicker than the standard power cube with angle, where most of the time was spent in setup and squaring. Squaring is automatic in the next case. &lt;br /&gt;
:*Material waste could be significant, but not if each side is cut in 2 pieces, so that 12 frame pieces are first welded into 6 sides, then the assembly is welded into the finished product. This moves steel sheet use efficiency from 30% to about 90% efficient for 2&#039; frames.&lt;br /&gt;
*Focus on even easier access to parts.&lt;br /&gt;
*Remote throttle and starting cable.&lt;br /&gt;
*Pull start for use without battery&lt;br /&gt;
&lt;br /&gt;
Minimum viable product:&lt;br /&gt;
#Engine&lt;br /&gt;
#Pump with quick connects.&lt;br /&gt;
No hydraulic cooler, cooler fan, cooler grate and battery. Good for intermittent use, or coninuous below 75F ambient temperature.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;== FreeCAD FEM Workbench ==&lt;br /&gt;
The FEM Workbench provides modern Finite Element Analysis (FEA) workflow for FreeCAD. The finite element method (FEM) is a numerical method for solving problems of engineering and mathematical physics. It is also referred to as finite element analysis (FEA). Typical problem areas of interest include structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential.&lt;br /&gt;
&lt;br /&gt;
== How to use FEM in FreeCAD ==&lt;br /&gt;

* https://forum.freecadweb.org/viewtopic.php?f=13&amp;amp;t=23547&lt;br /&gt;
 &lt;br /&gt;
== Background ==&lt;br /&gt;
Inspiration for this wiki page came from a thread on the FreeCAD (FC) forums of a user who used FC to model and mill a hose-housing mounted to a wall that broke at his home. Cura said he&#039;d need 526g of filament and ultimately the print 3D print took 28 hours. An FC community member examined the model and wondered what a FEM analysis would show. Along comes an FC FEM enthusiast and runs one. The results are enlightening: [https://forum.freecadweb.org/viewtopic.php?f=24&amp;amp;t=23655v FreeCAD saved the Day ! (hosepipe bracket)] In short he could of used 20% of the original mass which would of rendered ~20% of printing time which means 28hours -&amp;gt; ~6hours.&lt;br /&gt;
&lt;br /&gt;
== FEM discussions ==&lt;br /&gt;
Most of the discussions happening for FEM in FC are in the FEM subforum https://forum.freecadweb.org/viewforum.php?f=18&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
= Automatic capacitive sensing version of CNC Torch Table Height Controller =&lt;br /&gt;
&lt;br /&gt;
This is the automatic height levelling version based on the new TorchHeightCTRL_V.02 pcb. (All Sources on GitHub: [[https://github.com/case06/TorchHeightCTRL]])&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Warning: The phoenix-contact powersupply connector has NOT the same configuration than the connector of the same type on RAMPS-boards !!!&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Dont use the plug of a powersupply that was previously configured for use with a RAMPS-board and has 2 x 12V. The TorchHeightCTRL_V02 board has 1 x 5V and 1 x 12V and will be blown immedately if you give 12V to the 5V line !!!&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Firmware ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Arduino-Code on Github:[[https://github.com/case06/TorchHeightCTRL/blob/master/firmware/torchhc02k/torchhc02k.ino]]&lt;br /&gt;
&lt;br /&gt;
= Manual adjustable version of CNC Torch Table Height Controller =&lt;br /&gt;
&lt;br /&gt;
This is a simple POC-version that allows a manual adjustment of the Z height by turning a jog wheel (see demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]). The wheel can be 3d-printed [https://www.thingiverse.com/thing:17404] and is connected to a rotary encoder of type KY-040.&lt;br /&gt;
&lt;br /&gt;

&amp;lt;/gallery&amp;gt;&lt;br /&gt;
&lt;br /&gt;
- demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Design Rationale==&lt;br /&gt;
&lt;br /&gt;
With this rig it should be possible to manually operate the torch table height by following its slowly moving and regulate the height personally. This can be useful even if in the full version there is a capacitive sensor doing automatically that task, but one may use it then for setting the starting height or use it in other applications where a frequent manual control is an appreciated option.&lt;br /&gt;
&lt;br /&gt;
The rotary encoder gives up to 20 pulses per revolution to an Arduino-Mega, which translates it into a number of motor steps and triggers these by a TB6600-based stepper-driver.  A RAMPS 1.4 may act as a connection layer on top of the Arduino, but can also be omitted. We will show here which pins to wire on the Arduino and on the Ramps as well.&lt;br /&gt;
&lt;br /&gt;
The firmware consist only of a few lines of Arduino-code, which makes it easy to extend and modify.&lt;br /&gt;

|}&lt;br /&gt;
&lt;br /&gt;
== Wiring ==&lt;br /&gt;
&lt;br /&gt;
There are 3 kind of connections:&lt;br /&gt;
&lt;br /&gt;
- Power-supply to Ramps/Arduino&lt;br /&gt;
&lt;br /&gt;
- Rotary Encoder to Ramps/Arduino&lt;br /&gt;
&lt;br /&gt;
- TB6600 to Ramps/Arduino&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&amp;lt;gallery widths=&amp;quot;420&amp;quot; heights=&amp;quot;400&amp;quot; perrow=&amp;quot;2&amp;quot;&amp;gt;&lt;br /&gt;
Os manthc ramps-wiring1.png | Ramps-pins to connect are marked with a blue point&lt;br /&gt;

&amp;lt;/gallery&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=== Power-supply to Ramps/Arduino ===&lt;br /&gt;
&lt;br /&gt;
1. Ramps:  Connect a 12V/5A-Line to the MSTBA4-Port an the Ramps, by using a phoenix-contact plug. This will provide power for Motor as well as board-power for the Arduino-Mega.&lt;br /&gt;
&lt;br /&gt;
2. Arduino standalone: The Arduino musst be supplied with 5V to 12V. This can be done by the USB-connection to a desktop-pc or by a standard wall-wart ac/dc-adaptor (5V, 2A) for the Mega.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=== RotaryEncoder to Ramps/Arduino ===&lt;br /&gt;
&lt;br /&gt;
The KY-040 RotaryEncoder has 5 Lines: GND, +5V, SW, DT, CLK.  Connect these either to the AUX2 port of the Ramps, or directly to the corresponding digital I/O ports on the Arduino-Mega. &lt;br /&gt;
&lt;br /&gt;
GND --&amp;gt; GND&lt;br /&gt;
&lt;br /&gt;
5V  --&amp;gt; 5V&lt;br /&gt;
&lt;br /&gt;
SW  --&amp;gt; D44&lt;br /&gt;
&lt;br /&gt;
DT  --&amp;gt; D42&lt;br /&gt;
&lt;br /&gt;
CLK --&amp;gt; D40&lt;br /&gt;
&lt;br /&gt;
&amp;lt;gallery widths=&amp;quot;420&amp;quot; heights=&amp;quot;400&amp;quot; perrow=&amp;quot;2&amp;quot;&amp;gt;&lt;br /&gt;
Os_manthc_knob1.jpg | KY-040 RotaryEncoder with 3d-printed jog-wheel&lt;br /&gt;
Os_manthc_knob2.jpg | The pins at the AUX2 port are conected to the rotary encoder&lt;br /&gt;
&amp;lt;/gallery&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== TB6600 to Ramps/Arduino, Motor and Power ===&lt;br /&gt;
&lt;br /&gt;
The TB6600 stepepr driverhas three phoenix contact like connectors, &lt;br /&gt;
&lt;br /&gt;
- one 6-pin to the Ramps&lt;br /&gt;
&lt;br /&gt;
- one 4-pin to the motor&lt;br /&gt;
&lt;br /&gt;
- one 2 pin to power-supply&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The 6-pin connector&#039;&#039;&#039; has the lines ENA-, ENA+, DIR-, DIR+, PUL-, PUL+.&lt;br /&gt;
&lt;br /&gt;
Make a bridge between ENA- and DIR-, together with a second bridge from DIR- to PUL-.  The PUL- contains a second cable which goes towards GND on the Ramps Extruder E0 port. So in total there are 4 wires going either to the Ramps or directly to the Arduino-Mega:&lt;br /&gt;
&lt;br /&gt;
1. Ramps:&lt;br /&gt;
&lt;br /&gt;
ENA+ --&amp;gt; EN&lt;br /&gt;
&lt;br /&gt;
DIR+ --&amp;gt; DIR&lt;br /&gt;
&lt;br /&gt;
PUL+ --&amp;gt; STEP&lt;br /&gt;
&lt;br /&gt;
PUL- --&amp;gt; GND&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
2. Arduino-Mega:&lt;br /&gt;
&lt;br /&gt;
ENA+ --&amp;gt; D24&lt;br /&gt;
&lt;br /&gt;
DIR+ --&amp;gt; D28&lt;br /&gt;
&lt;br /&gt;
PUL+ --&amp;gt; D26&lt;br /&gt;
&lt;br /&gt;
PUL- --&amp;gt; GND&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&amp;lt;gallery widths=&amp;quot;420&amp;quot; heights=&amp;quot;400&amp;quot; perrow=&amp;quot;2&amp;quot;&amp;gt;&lt;br /&gt;
Os_manthc_Tb6600_wiring1.png | upper left corner: 2 white cables make a bridge between ENA-, PUL- DIR-.   The PUL- contains an additional cable (orange) that connects to GND on the Extruder E0 port of the Ramps/Arduino&lt;br /&gt;
Os_manthc_ramps-wiring2.jpg | The pins at the extruder E0 port are connected to the TB6600&lt;br /&gt;
&amp;lt;/gallery&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The 4-pin connector&#039;&#039;&#039; has the lines A+, A-, B+, B-.&lt;br /&gt;
&lt;br /&gt;
In the case of a bipolar stepper motor with 4 wires two of them are the ends of one coil. Connect them like this:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&amp;lt;gallery widths=&amp;quot;420&amp;quot; heights=&amp;quot;400&amp;quot; perrow=&amp;quot;2&amp;quot;&amp;gt;&lt;br /&gt;
Os_manthc_stepper_wiring1.png | &lt;br /&gt;
&amp;lt;/gallery&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
An example for a tested Nema17-stepper with 2A and 59Ncm holding torque is the 17HS19-2004S, see [http://www.omc-stepperonline.com/download/pdf/17HS19-2004S1.pdf], [http://www.omc-stepperonline.com/3d-printer-nema-17-stepper-motor-59ncm84ozin-2a-17hs192004s-p-18.html].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The 2-pin connector&#039;&#039;&#039; has the lines 12V+, 12V-.&lt;br /&gt;
&lt;br /&gt;
Connect these to a power-supply which can deliver at least 5A.  The TB6600 stepper driver is rated for up to 4A and 9-36V DC.  That means you can instead of 12V also connect 24V or more towards it.&lt;br /&gt;

&lt;div&gt;{{Hint|Note that the FreeCAD 101 Test has been moved to [[Developer Test]]}}&lt;br /&gt;
[[Category:FreeCAD]]&lt;br /&gt;
=Overview=&lt;br /&gt;
&lt;br /&gt;
FreeCAD is a free and opensource program for designing structures, parts, and machines. It is mostly used in architectural and mechanical engineering contexts. OSE uses FreeCAD both for its mechanical design work for the machines in the [[Global Village Construction Set]], and for helping create educational documents for teaching people to build those designs. &lt;br /&gt;
&lt;br /&gt;
As OSE grows, this page will be our junk-drawer &amp;amp; repository of all FreeCAD materials organized under the following scheme: General Resources (manuals, YouTube series, forums); and Task-Specific Tutorials for current projects we have (creating a cube, simplifying files,  exploded parts diagrams, &#039;&#039;etc.&#039;&#039;). This wiki is a sort of live and grow user generated OSE FreeCAD manual. As the list of tasks grow, we can further organize this material.  &lt;br /&gt;
&lt;br /&gt;
*General FreeCAD Resources&lt;br /&gt;
*Task 1: Create Cube (For Developer Test) &lt;br /&gt;
*Task 2: Extract dimensional Drawings &lt;br /&gt;
*Task 3: Simplify Files (for Parts)&lt;br /&gt;
*Task 4: Combine Parts into Final Assemblies&lt;br /&gt;
*Task 5: Extract Isometric Views from Final Assemblies for Exploded Parts Diagrams&lt;br /&gt;
&lt;br /&gt;
=General FreeCAD Resources=&lt;br /&gt;
Here are some general resources for familiarizing yourself with FreeCAD. &lt;br /&gt;
*&#039;&#039;&#039;Manuals:&#039;&#039;&#039; [https://www.gitbook.com/book/yorikvanhavre/a-freecad-manual/details The FreeCAD Manual] by Yorick for a much nicer first contact with program than the [http://www.freecadweb.org/wiki Official FreeCAD Documentation Wiki]. [[FreeCAD Architecture Tutorial]]&lt;br /&gt;
*&#039;&#039;&#039;Forums:&#039;&#039;&#039; [https://forum.freecadweb.org/ General FreeCAD Forum] [https://forum.freecadweb.org/viewforum.php?f=3&amp;amp;sid=b8a27386b60e8f3732887946f40babaa Help on Using FreeCAD]&lt;br /&gt;
*&#039;&#039;&#039;Video Series:&#039;&#039;&#039; Rick Hoefer&#039;s [https://www.youtube.com/playlist?list=PLSLeSKyjWpVYxz7kpTmPfxMAzE6SxIIfV Intro to FreeCAD for 3D Printing series], [https://www.youtube.com/playlist?list=PL-1acotz9dg4Pz5-8RvVGf-AqbnZxhUZ_ FreeCAD for Dummies ], Mindscraper&#039;s [https://www.youtube.com/playlist?list=PLqBJkD97Q9wVGqT3dXcOaQNrS2nfVbE0o FreeCAD Playlist]&lt;br /&gt;
*&#039;&#039;&#039;OSE Introductory Tutorials:&#039;&#039;&#039; &lt;br /&gt;
Note: the following tutorials are dense. Please pause the videos as needed in order to practice the demonstrated lesson. &lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
Tutorial 1.1 Introduces the sketcher workbench in FreeCAD, so you can then create any 3D objects imaginable&lt;br /&gt;
&lt;br /&gt;
&amp;lt;html&amp;gt;&amp;lt;iframe width=&amp;quot;480&amp;quot; height=&amp;quot;270&amp;quot; src=&amp;quot;https://www.youtube.com/embed/RwcFg-anVHE&amp;quot; frameborder=&amp;quot;0&amp;quot; allowfullscreen&amp;gt;&amp;lt;/iframe&amp;gt;&amp;lt;/html&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Tutorial 1.2 Introduces part libraries. Importing parts from libraries and assembling them is a powerful way to do design work. This can get the casual user to powerful design capacity using real geometries.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;html&amp;gt;&amp;lt;iframe width=&amp;quot;480&amp;quot; height=&amp;quot;270&amp;quot; src=&amp;quot;https://www.youtube.com/embed/RLRppdFAtzY&amp;quot; frameborder=&amp;quot;0&amp;quot; allowfullscreen&amp;gt;&amp;lt;/iframe&amp;gt;&amp;lt;/html&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=Task 1: Create Corner Cube (For Developer Test)= &lt;br /&gt;
&#039;&#039;&#039;For the Developer Test complete the following instructions.&#039;&#039;&#039; You will create a corner cube: use the sketcher, part, part design, bolt, and assembly workbenches; and  import, rotate, and align parts; make features on faces; and install bolts. After this, you should be ready to begin to work on basic [[User Contributed Designs]]. (Note: You will later submit a screen-cast video of this process. If you are comfortable with FreeCAD and screen-capturing video, you may video your first attempt. Otherwise, use this as a practice round, and once you learn to make the corner cube, come back to document it.)   &lt;br /&gt;
&lt;br /&gt;
#&#039;&#039;&#039;Review OSE&#039;s Introductory FreeCAD Tutorials 1 &amp;amp; 2 above in the General resources. (Refer to other sources as needed.) Also, review the self-verifying exams videos &amp;amp; comments on the [[Developer Test]] page.&#039;&#039;&#039;&lt;br /&gt;
#&#039;&#039;&#039;Download 8-hole square tubing (without rounded corners) from the [[OSE Part Library]].&#039;&#039;&#039;&lt;br /&gt;
#&#039;&#039;&#039;Use the tubing to create an x-y-z bolted corner cube.&#039;&#039;&#039;&lt;br /&gt;
#&#039;&#039;Record a video of you building the cube, from the beginning, using [[Vokoscreen]]. Please refer to [[Vokoscreen 101]].&#039;&#039;&lt;br /&gt;
#&#039;&#039;&#039;When you are done building the cube, create a 1&amp;quot; bolt and nut using the [[Fastener Workbench in FreeCAD]].&#039;&#039;&#039;&lt;br /&gt;
#&#039;&#039;&#039;Insert one bolt through any of the corners, as if you were actually building the cube - using the [[Assembly Workbench]] in FreeCAD.&#039;&#039;&#039; &lt;br /&gt;
#&#039;&#039;&#039;Tighten the bolt with the nut (just insert the nut onto the bolt).&#039;&#039;&#039;&lt;br /&gt;
#&#039;&#039;&#039;Now take any face on the tubing of the resulting cube - and using Sketcher on that particular face - write your initials on that face. Pocket those initials so that they are cut into the face.&#039;&#039;&#039;&lt;br /&gt;
#&#039;&#039;End video capture&#039;&#039;.&lt;br /&gt;

When you are finished with &#039;&#039;Part 2: Design a Cube in FreeCAD&#039;&#039; go back to the [[Developer Test]] and complete &#039;&#039;Part 3: Document Your Work.&#039;&#039;&lt;br /&gt;

To be completed...&lt;br /&gt;
&lt;br /&gt;
=Task 3: Simplify Files (for Parts)=&lt;br /&gt;
Goals: Redraw certain parts to reduce file size. Among other things OSE is currently working on the [[Lyman Filament Extruder]] for making filament for our 3D printers. We have rich files for each part that is ready to be purchased or printed. However, many of the files are too large to combined with other rich files into an assembly. OSE needs to combine all the parts into an assembly to 1) interact and modify a whole machine or module more easily; and 2) use for visual instructional materials. Please see [[File Simplification]] for reference.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
=Task 4: Create Final Assemblies= &lt;br /&gt;
Now to see the forrest for the trees, we sometimes have to put all of our individual part files together and see how they fit, etc. Once all the parts (stl files) are together in an assembly, we can now use it for modifying the existing design, or for creating educational materials based on the design. &lt;br /&gt;
