Bem was quicker than me :)
Regarding the doors, windows, etc.. No, such thing is useless (plus it would be a hell to develop it), it's possible to assign those types directly from the BIM environment once you have imported the IFC, if you need. For instance, after importing the IFC, you can save something as "door" and then place it parametrically inside a wall. But that's not the main purpose for me. The purpose is a clean 3D model inside BIM software for producing documentation (especially sections with vectorial shadows), and listing of the elements for calculating surfaces and volumes.

Hi Max,

> Regarding the doors, windows, etc.. No, such thing is useless <....>

Ok, but then what is it that you would be trying to gain by using IFC format rather than one of the other standard CAD formats like 3DM, STEP, IGES and SAT which already transfer surface data without doing any triangulation?

Are none of those formats supported by your BIM software?

Only .STL. Tried it, and it works quite well, also .SKP is even better.
Thank you for the advice, didn't think about it, sorry!
