Revit does not export correct wall opening to IFC

[Johris]

Hi!

We have a problem with wall opening from Revit to IFC. Any ideas or a bug? Maybe @angel_velez  know?

Revit 2020.

IFC 2x3 (Tried IFC4 as well, same result)

Using Revit IFC exporter 20.1.0.2

Attached is a sample file of our Revit model and IFC.

In Revit:

In IFC:

In Revit the opening is made by our Door-family. And it is a correct wall opening in our Revit model. But not when exported to IFC.

FWIW: No problems here.  You sure you are doing it right?  Seems pretty straight-forward.  I can't imagine what you did wrong.

Got help from the support. THe Door-portal family contained several wall openings. It was fine in Revit but not when export. So make sure Door-familys only contain one wall opening.

We are experiencing the same problem The door opening is correct in Revit (right image) but is not existing in the IFC (left side). I am attaching a Revit 2021 project with that door family, and the exported IFC.

I only see 1 opening cut in my family.

What is going on?
