The "Export to IFC" tool only exports the default model, not the active one.

This is a big problem with OR since in most cases, the default model is the 2D. So we have to have the 3D reference turned on for it to export our objects.

We end up with an overpopulated ifc with a lot of 2D unwanted objects..

Our workaround is to creat a second dgn with only a 3D model in it, then reference the 3D models we want to export to ifc. A lot of extra work and extra files..

And if we are talking about DU, if the 2D model is not present along side the 3D, the properties and ItemTypes won't be exported as they should.
