IFC Beams not joining

[Patrick M]

I have seen this a lot, and other than saving BREP, which is not ideal for obvious reasons, I have not found a way to resolve complex profile beams exporting to IFC. Is there some burried translator issue? are beams classified as coverings not recognizing actual geometry? what gives?

These two eave/soffit profiles are supposed to be mitered, but show block ended in solibri MV.

You always need to make it a BREP.

All other options are basically useless, because you give up the control to the opening program, which in 99% of all cases will do something different than intended.

What you want, the reusable so called Design Transfer was never actually finished in the spec. I'd never give out IFC files not using BREP.

I've found BREP models in Revit, in particular, to be difficult to snap to and align. I only send BREP in a last ditch attampt to get things right, but expect consultants to snap to dwg or use given dims from pdf, rather than snapping to model faces/edges.
