amrit3701 / docker-freecad-cli Goto Github PK

Hi,

I'm trying to use your container to generate CAD models.
Since I don't have root permissions on the host system I'm trying to generate the CAD files with ownership set to my user id.

I run the container with the option -u UID:GID. id reports the right IDs for the user.

But when starting python, I get the following output

I have no name!@75d087d8d5b6:/home$ python3.8
Python 3.8.5 (default, Jul 20 2020, 19:48:14)

Initialization of FreeCAD failed:
While initializing FreeCAD the following exception occurred: 'Getting HOME path from system failed!'


Please contact the application's support team for more information.

Traceback (most recent call last):
  File "/.startup.py", line 1, in <module>
    import FreeCAD
ImportError: Failed to load FreeCAD module!

I looked around the forum, but didn't find any solutions.
Do you know of a way to fix this?

Hi @amrit3701 ,
Thanks for your work !
I'm looking for adding a new workbench to the raw Freecad build (sheet metal).
How would you do that ?

I ask because I don't see a 0.21 directory

Obviously it has a dependency on the front end, and we're trying to run headless, so I doubt this is going to be an easy problem to solve.

Any general advice on how to get the union of two meshes in an automated fashion, please? I've tried pymesh. I've tried converting to a Part.Shape with makeShapeFromMesh and calling fuse. Neither approach yeilds a mesh which is valid according to or repairs correctly in FreeCAD. The OpenSCAD workbench in FreeCAD does it nicely, but is now putting up a fight when I try to automate it

We're discussing the importance of having documentation for how to maintain different ways to run/build FreeCAD in FreeCAD/FreeCAD-Bundle#158 (comment). @amrit3701 would you consider documenting what is involved in maintaining docker-freecad-cli ?
