FreeCAD Downloads[edit]

{{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/?title=Download to choose the correct build for your Operating System.


Learning FreeCAD[edit]

Current Work[edit]

Tractor Construction Set Specification for FreeCAD.

Strategy[edit]

Collaborate with open source support institutes such as INRIA to develop FreeCAD to open source product development standards.

Original Specification[edit]

FreeCAD Review[edit]

See FreeCAD Assessment

OSE FreeCAD Needs[edit]

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

Action Plan[edit]

  • 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.

Process for Developing FreeCAD Instructionals[edit]

OSE FreeCAD Documentation[edit]

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 [3].


OSE FreeCAD Requirements[edit]

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 mounse)?
  • 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[edit]

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 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.

  • Yorik van Havre, Daniel Falck, and Brad Collette - Path Workbench
  • Ian Rees - crowdfunded individual working on Drawing Workbench
  • gCAD3D appears to be viable for CAD/CAM - [4]
  • Przemo Firszt, Bernd Hahnebach - CAE workbench
  • Sebastian Hoogen - OpenSCAD workbench
  • FEA, macros - psicofil, Lucio Gomez - [5]

  • 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]
