... it makes one, big, all-in-one IfcBuildingElementProxy object... But at least it imports fine in FreeCAD! It is not of big use if it is one huge big object. But FreeCAD can only import what it gets. But the imported geometry looks cool :) and FreeCAD is able to do cuts. At the end it helps ifc. ...

It's a pity FreeCAD adopt the word layers for this kind of funktionality. It's not I don't like the funktionality to group elements it's just the word layer is not convenient for it. The word layer never ever was convenient for just a element property. In whole BIM and ifc world a layer is a part of...

Ah I managed to compile. There was a caps problem, when it tries to link to the carve lib, it uses -lcarve (which looks for a libcarve.a or libcarve.so file) but the compiled carve lib is Release/libCarve.so (big C). So I did a simlink named libcarve.so in the same folder and things worked. Thanks ...

Does this one helps too? https://sourceforge.net/p/ifcopenshell/ ... it=50#fd81

Sure, find attached a circle and oval (they are really comon here in Switzerland) columnd exported using Allplan 2014.0.3

At the moment they are called ???, but if someone has a better idea, I would be grateful. Drawing is...

Yes, they are.

Export works even for sophisticated modells quite well. @Yorik, you don't like columns do you? Since all of them are removed by now the basement floor could be used for soccer or stuff like that.

Thomas has allready adopted ifcopenshell :) It gives a shape for IfcReinforcingBar. >>> import IfcImport >>> import Part >>> i=IfcImport.open("/home/hugo/Documents/projekte--ifc/freecad/IfcReinforcingBar.ifc") >>> ss=IfcImport.create_shape(i.by_id(19269)) >>> s=Part.Shape() >>> s.importBre...
