in my ifc file these values are wrong ... #73=IFCDIRECTION((0.,-5.33066907387547E-16,-1.)); #74=IFCEXTRUDEDAREASOLID(#69,#72,#73,0.2); it would work with #73=IFCDIRECTION((0.,-5.33066907387547E-16,1.)); #74=IFCEXTRUDEDAREASOLID(#69,#72,#73,10.2); but they might not be correct, because may be the pla...

If I export the ifc I only have 2 walls and 2 openings in the ifc. In your ifc are 2 walls, 2 opening, and 2 IfcBuildingElementProxies. The last ones are these huge extrusions.

[*]Surprise to see 2nd extrusion is exagerated - 1000 times of original ? (mm interpreted as m?) Screenshot from 2020-08-02 12-11-41.png attached your ifc in BIMCollabZoom, the correct subtration (typo in your file) are exported as openings (red), but additionaly there are these extrusion with a le...

I have been away a few days ...

If we would follow FEM naming shema we would need to call all the names freetextinput_whatIsTheTextInputFor.py etc

Harmonizing the coding style will cause a lot of merge conflicts for big-effort branches like realthunder's. My ConstraintSolver will be affected noticeably, but not critically, as most of the code is in a new module. So i'm a bit against. If it has to be done, I think sooner is better than later, ...
