Make boolean objects editable

Open smr02 opened this issue 1 year ago • 6 comments

I've created a beam from the BlenderBIM demo project with a void and imported it to FreeCAD.

In the screenshot you can see how the Void/opening shows as a very small cube in FreeCAD. Attached the IFC file.

A heads up that for these types of openings you should typically not use "openings", you should instead use boolean difference voids.

@Moult, right. I'm still trying to figure out my workflow. I guess, FreeCAD can't display a boolean difference void yet? Can it create them?

yorikvanhavre is AFK.. If you don't hear a response from a week from today please bump this ticket again, @smr02 TIA

Sorry for the delay!

The very small cube is probably due to a workaround we use right now, that creates such a "default" shape to prevent objects to have a null shape (because of a bug in FreeCAD that auto-populates such shapes). But I'll look further into this one...

About boolean ops, indeed you can see the result but not yet edit them. Coming soon ;)
