Importing the attached IFC (created from the file in this topic) causes FreeCAD to hang with a 'list index out of range' error.

It imports fine in my system.

>>> import ifcopenshell

'0.6.0b0'

However, if you use IfcPlusPlus, the two groups of beams are imported in the same place.

I still have the problem after upgrading. Only if I uncheck 'Detect extrusions' (see topic title) can I import the file.

That is correct. But with that file FreeCAD does not hang.

Unchecked "Detect extrusions".

Checked "Detect extrusions". The direction of the extrusion is different. I assume this could be improved.
