IFC Versions in xBim

[GVladislavG]

Hello, xBim team!

I have some questions about supported IFC versions in xBim.

1. Does IFC4 SchemaVersion equal IFC 4.0.2.1? Or some other subversion?
2. Does IFC4x3 SchemaVersion equal IFC 4.3.2.0? Or some other subversion?
3. How about Model View Definition (MVD)? Is there any way to set it?
   Or what MVD does IFC-file, created by xBim, have?

Thanks!

Generally said, we implement the versions published as ISO standards. That is 2.3.0.1, 4.0.2.1 and 4.3.2.0. We don't impose any specific MVD. So, if you use the Toolkit to create the data, you can implement any MVD you like. There are MVD validation tools which you should then make part of your development to make sure you have developed an exporter which complies with specific MVD.
