Drag & Drop failed - no module named 'ifcopenshell.api.spatial.unassigned_container'

[balrobs]

When I try to move a newly created Wall001 into the "My Storey" container by drag and drop I run into this error:

When I drag and release it over the existing wall (I know this doesn't make sense) I run into a "Access violation"

This is not happening for me here... Maybe try to update your version of ifcopenshell?

[balrobs]

import ifcopenshell
print(ifcopenshell.version)
0.7.0

I will investigate further!

[yorikvanhavre]

Yeah mine is 0.7.0 too, but it has new commits and fixes almost every day 😅

No crash for me here:

I noticed a small bug though, the object is not removed from the Site when dragging it onto the storey, that is fixed with commit 95e87f3

Not sure if that's the origin of your crash, though.. Can you retest?

[balrobs]

Yes, your commit solved the crash on my site!

[yorikvanhavre]

Great! Thanks for confirming!

BTW that files gives errors when opened in IFC++, and also the objects appear black for me when opened in FreeCAD. But not sure what exactly is happening...
