I understand your position, I confess that my focus is being on FreeCAD and therefore, I would like your authorization to be able to continue with your project starting from your code. Do you authorize me? Of course I authorize, feel free to do what you want. I didn't make it available on github du...

I was honestly fascinated by the project and I would certainly like to collaborate by testing... Hi, Thanks for your opinion. As I said before, this was a test of my learning. As BlenderBIM is further along in 4D and 5D development (all in IFC), I don't think it's worth continuing with this WB. Gre...

if you need a quick transitional solution, you could make a simple copy in part before the export and export it. it is enough to get the geometry. Sorry, I do not understand. Use Part WB / Create simple copy? This is not the case, as Arch/Ifc modeling is lost. The issue here is not the solution to ...

I did this test and only par-003 changed.

Other beams also have Axis-z = -1 and do not change.

Yes(structural wall/beam).

I tried but the behavior persisted.

Hi all,

If I recompute the whole document the offending wall also changes position in FreeCAD. Recompute hasn't changed anything here. BTW moving the wall to its correct position solves the problem definitely. Cheers! Yes, I noticed that too. In this (relatively small) project, this change is visible, but ...

Hi all, Before exporting to IFC: print_1.png After export: print_2.png The element indicated in the figure changes position automatically and is exported in this new position (when imported into Blender, it is in the wrong place). And the groups are being exported as IFCBUILDINGELEMENTPROXY and not ...
