Dear all,

I’m compiling a list of geometrical concepts / paradigms in IFC. Essentially everything that relates to geometry in some way. The purpose is for alignment to other standards. I’d be grateful if you could have a look and let me know your thoughts on comprehensiveness and correctness.

Thanks in advance, Thomas
