HintLightbulb.png Hint: FreeCAD is open source Computer Aided Design (CAD) software that OSE uses on a regular basis to produce 3D designs, fabrication drawings, exploded part diagrams, and other assets indispensable to the design of physical objects

Basics

  • A FLOSS CAD software
  • It is currently (as of 2020) OSE's official CAD software
  • It is also a part of OSE Linux v1.0 (using FreeCAD 0.16) in OSE's custom Linux distribution

Most Recent Versions

  • "The latest bug fix release 0.18. 4 (16146) "

See 3/7/16 update on OSE FreeCAD Workbenches -

FreeCAD Downloads

HintLightbulb.png Hint: The OSE Linux distribution is a complete distribution which includes all development software for OSE, and FreeCAD is a staple of that stack

See http://www.freecadweb.org/wiki/Download to choose the correct build for your Operating System.

FreeCAD 0.16 AppImage

FreeCAD 0.16 Appimage Notes

Hi Marcin, I just tested my workbench with an Appimage. https://github.com/FreeCAD/FreeCAD/releases/download/0.18.4/FreeCAD_0.18-16146-Linux-Conda_Py3Qt5_glibc2.12-x86_64.AppImage and the recent version https://github.com/rkrenzler/ose-piping-workbench. The workbench works. I assume that PyQt5 could be a reason for the problem. When I started to develop ose-piping-workbench I used the old Version of PyQT then I ported the workbench to the new version. Maybe this is the reason why it worked before but it does not work anymore. Best regards, Ruslan

OSE FreeCAD Needs

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 simple, 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 [3].

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).Check.png
  • Adding parameters to all of the shapes, so they can be modified. Check.png
  • Modifying all parameters in 3D parametrically (typing in lengths) Check.png
  • Modifying all parameters in 3D with the mouse (such as dragging corners, edges, and faces)

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)? 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 mouse)?
  • For multiple objects, moving them with the mouse to arrange, mate, align them.

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?

Response from FreeCAD developer ickby: "not yet but will be possible with upcoming assembly workbench"

  • Maintaining parametric nature of grouped objects?

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?

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? 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 Update: Jurgen has not been active on the project for many years now. Kunda (talk) 13:46, 4 August 2018 (UTC)
  • 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 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. Update: User is dormant Kunda (talk) 13:46, 4 August 2018 (UTC)

*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. Update: he left and returned but hasn't been active at all in the code or community Kunda (talk) 13:46, 4 August 2018 (UTC)

  • 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. 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 publicly. This may change. Kunda (talk) 13:46, 4 August 2018 (UTC)
  • tanderson69 is very good in OpenCascade, so he can work on difficult tasks that have to do with the CAD geometry kernel. Update: Participates on the forum and very sporadically on the code. I believe he is involved in another project.

  • Lars G. - IGES files to house cross sections in architecture - [8]
  • Kwasny - macro example of how to create an Icon in the workbench that allows you to draw a piston ring by clicking on the icon. This way, the macro (a set of commands) was actually turned into a tool - [9]
  • Dan's Open Source Design Tools, with motto to be free from black-box CAx toolchains - [10]
