==Action Plan==

* Recruit software developer to analyze FreeCAD and build with/upon their work. Short-term Objective: Get Assembly Module Working.
* Document FreeCAD source code in github repository.
* Document FreeCAD's code structure. (some preliminary work available at https://github.com/qingfengxia/FreeCAD_Mod_Dev_Guide)

=OSE FreeCAD Documentation=

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]]

[[File:FreeCAD-3.pdf]]

This document covers the following topics:

* Views
* Workshops
* Sizing a Primitive Part
* Positioning a Part
* Making a Cut
* Combining Parts
* Rotating a Part
* Extrusion

See also, FreeCAD Documentation and Tutorials [http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Main_Page].

=OSE FreeCAD Requirements=
For OSE to use FreeCAD for all of its design needs, these are the functions required. Do these exist? Please comment.

*Freehand drawing of shapes and extrusion (like Sketchup).[[Image:check.png]]
*Adding parameters to all of the shapes, so they can be modified. [[Image:check.png]]
*Modifying all parameters in 3D parametrically (typing in lengths) [[Image:check.png]]
*Modifying all parameters in 3D with the mouse (such as dragging corners, edges, and faces)

[https://github.com/ickby Response from FreeCAD developer ickby]: "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"

*Adding parameters in 3D parametrically (boolean operations)? [[Image:check.png]]
*Adding parameters in 3D by drawing them and extruding (mouse-based boolean operations)
*Adding parameters to shapes in 3D parametrically (such as drawing in new objects parametrically)?
*Adding parameters to shapes in 3D manually (such as drawing in new objects with a mounse)?
*For multiple objects, moving them with the mouse to arrange, mate, align them.

[https://github.com/ickby Response from FreeCAD developer ickby]: "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."

*Grouping and ungrouping objects into assemblies?

[https://github.com/ickby Response from FreeCAD developer ickby]: "not yet but will be possible with upcoming assembly workbench"

*Maintaining parametric nature of grouped objects?

[https://github.com/ickby Response from FreeCAD developer ickby]: "not yet, but will be possible with the upcoming assembly workbench"

Now for interoperability with other CAD packages:

*Importing multiple new objects into a drawing - one at a time?

[https://github.com/ickby Response from FreeCAD developer ickby]: 'currently you can only import whole files, not individual objects from a file'

*Importing multiple objects into a model - all at one time? [[Image:check.png]]
*Importing new objects while passing the parametric values into FreeCAD, such as with a STEP file?

=Contributors and Users=
From Kostas:
*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
*Werner Mayer is the most active developer in terms of commits, he is just awesome, I don'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.
*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.
*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.
*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.
*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.
*tanderson69 is very good in OpenCascade, so he can work on difficult tasks that have to do with the CAD geometry kernel.
*Daniel Falck is the person to contact for CAM integration.
*Kostas - sketcher module.

See [[FreeCAD Scripts]] for the list of top 10 instructionals that are needed.

==Action Plan==

* Recruit software developer to analyze FreeCAD and build with/upon their work. Short-term Objective: Get Assembly Module Working.
* Document FreeCAD source code in github repository.
* Document FreeCAD's code structure. (some preliminary work available at https://github.com/qingfengxia/FreeCAD_Mod_Dev_Guide)

=OSE FreeCAD Documentation=

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]]

[[File:FreeCAD-3.pdf]]

This document covers the following topics:

* Views
* Workshops
* Sizing a Primitive Part
* Positioning a Part
* Making a Cut
* Combining Parts
* Rotating a Part
* Extrusion

See also, FreeCAD Documentation and Tutorials [http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Main_Page].

=OSE FreeCAD Requirements=
For OSE to use FreeCAD for all of its design needs, these are the functions required. Do these exist? Please comment.

*Freehand drawing of shapes and extrusion (like Sketchup).[[Image:check.png]]
*Adding parameters to all of the shapes, so they can be modified. [[Image:check.png]]
*Modifying all parameters in 3D parametrically (typing in lengths) [[Image:check.png]]
*Modifying all parameters in 3D with the mouse (such as dragging corners, edges, and faces)

[https://github.com/ickby Response from FreeCAD developer ickby]: "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"

*Adding parameters in 3D parametrically (boolean operations)? [[Image:check.png]]
*Adding parameters in 3D by drawing them and extruding (mouse-based boolean operations)
*Adding parameters to shapes in 3D parametrically (such as drawing in new objects parametrically)?
*Adding parameters to shapes in 3D manually (such as drawing in new objects with a mounse)?
*For multiple objects, moving them with the mouse to arrange, mate, align them.

[https://github.com/ickby Response from FreeCAD developer ickby]: "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."

*Grouping and ungrouping objects into assemblies?

[https://github.com/ickby Response from FreeCAD developer ickby]: "not yet but will be possible with upcoming assembly workbench"

*Maintaining parametric nature of grouped objects?

[https://github.com/ickby Response from FreeCAD developer ickby]: "not yet, but will be possible with the upcoming assembly workbench"

Now for interoperability with other CAD packages:

*Importing multiple new objects into a drawing - one at a time?

[https://github.com/ickby Response from FreeCAD developer ickby]: 'currently you can only import whole files, not individual objects from a file'

*Importing multiple objects into a model - all at one time? [[Image:check.png]]
*Importing new objects while passing the parametric values into FreeCAD, such as with a STEP file?

Concurrent Engineering

2017-02-16T09:32:54Z

Kkremitzki:

=Definition=
''Concurrent engineering is a work methodology based on the parallelisation of tasks (i.e. performing tasks concurrently), which is sometimes called Simultaneous Engineering or Integrated Product Development (IPD). It refers to an approach used in product development in which functions of design engineering, manufacturing engineering and other functions are integrated to reduce the elapsed time required to bring a new product to the market.'' - Wikipedia

=Concurrent Engineering vs. Waterfall=
[[Image:concurrentvswaterfall.jpg|1000px]]

Kkremitzki:

There is an addon manager for FreeCAD available via a macro (https://github.com/FreeCAD/FreeCAD-addons) or built-in to current 0.17 dev builds. This addon manager allows for easy installation of extensions for FreeCAD and that includes a parts library (https://github.com/FreeCAD/FreeCAD-library).

Has there been any consideration to either (a) creating a GitHub repository to store the approved/master versions of these files which can then be made available in the addon manager or (b) integrating OSE parts into the existing parts library?

==Overview==

[[Image:Well-Drilling Rigpic.png|thumb|400px|Well-Drilling Rig]]

The '''Well Drilling Rig''' enables the construction of [[water]] wells. Water is crucial for human and animal consumption, washing, irrigation, and industrial processes. Access to clean [[drinking water]] is one of the key challenges facing many countries today. Addressing this need with the [[GVCS]] has the potential for far reaching impact.

If this machine plans are changed little to "General Drilling Rig" it can be used also mining purposes,
to drill & blast caves, make bolt holes, drill water and geothermal wells etc. There can be two
changeable drill heads. One for bigger holes (compressed air driven) and second hydraulic driven
(fast) for smaller holes. And modified [[LifeTrac]] may carry them. Modified [[Backhoe]] offer enough
movement for drill head tool.

==Description==
Well drilling can be broken down into three basic phases:

#breaking up the rock/soil in the well column
#removing the cuttings from the well column
#stabilising the well column and preparing it for production.

'''Breaking'''
Breaking of rock/soil to produce cuttings is achieved by a cutting tool, either a rotating drill bit or a raised and dropped 'chisel-like' device; for the ''GVCS well drilling rig'' we will likely employ the rotating bit design as it is a much more common method of well preparation. The bit is rotated by attaching it to the end of a long series of pipes connected together called the drill string, turning the drill string turns the cutting bit.

'''Pumping'''
Once the bit has cut up the rock/dirt it needs to be lifted up out of the well. The most common way of doing this is to pump water/mud down the center of the piping that makes up the drill string, and letting it flow out the end of the bit. By continuously pumping more drilling mud into the well, it eventually fills up and the only place left for the mud to go is to be pushed up to the top of the well and spill over the side, carrying the cuttings along with it. This flow of mud and broken up rock spills over the top of the well and is sent to a small settling pond where the rocks and sand settle out of it. After some time in the settling pond the mud is recycled by the mud pump and pushed back down the well again to pick up and remove more cuttings allowing the well to be contiuously drilled deeper and deeper, stopping only to add new sections of drill string.

'''Stabilizing'''
After the well is drilled to the desired depth it must be finished and put into production. The drill string is withrawn from the well, but the well is left full of water/drilling mud to prevent the sides from caving in until the well is finished. After the drill string is out the casing pipe is slid into the well to prevent caving in of the sides. Once this is done, the drilling mud is removed from the well column leaving it empty. At this point a water bucket or temporary well pump is placed in the well and as much water as possible is drawn up for a test period of 1 to 3 days to clean out any remaining drilling mud and stabilize the aquifer for production. Also during this time the water extraction rate is measured to verify that it is worth continuing to finish the well (poor producing wells may have the casing withdrawn and be re-drilled at a more favorable location). Once the well is shown to be a producing well it is capped with a cement cap, and the water pump is installed making the well operational.

Kkremitzki: /* Worth generalizing? */

What about a wood fired baking oven. There are versions derived from the rocket stove that are quite efficient

== Worth generalizing? ==

The general need here, I think, is food-grade controllable heat delivery. This utility is often combined into an oven and range, and allows for heat processing of agricultural and food products. Perhaps keeping that in mind is worthwhile when it comes time to design this machine.

I also don't think this will be a one-size-fits-all solution. Other machines will enable the manufacture of different types of ovens & ranges, but a general design goal is getting the most useful food processing out of a given amount of fuel. Traditional earthen ovens cook different dishes at different temperatures as the oven cools from its initial firing.

It'd be interesting to combine a given design with a heat transfer model to be able to come up with a temperature over time profile and estimate how much cooking could be done. One possible start to creating that sort of model would involve combining FreeCAD Python scripting to handle a design's geometry, in addition to leveraging the existing work of the <tt>ht</tt> library (https://github.com/CalebBell/ht), a component of Caleb Bell's Chemical Engineering Design Library (ChEDL), an MIT-licensed group of Python libraries.
