From two or three days, I have stuck in one problem about IfcOpenHouse.ifc. My problem is that in a code this file is present but I have not downloaded this file but after download all things correct.

Today I understand a little bit code of “Using the parsing functionality of IfcOpenShell interactively” and “Using IfcOpenShell and pythonOCC to construct new geometry”.
