Openings in floors

[JohnFNordmark]

When we export with 2022.5.2 pre release Revit doesn't export openings in floors correct. We use the IFC 3x2 coordination view.

We noticed that, too. I think this started after 22.4.2, not entirely sure, though. Previously, this behaviour was limited to sloped slabs only.

This looks fixed in the 23.2.3 exporter for openings with straight edges:

Update: "Openings in floors" - Further Information Needed

Hello @JohnFNordmark and @andydandy74,

Thank you for reporting the issue regarding incorrect export of openings in floors from Revit 2022.5.2 to IFC2x3.

We appreciate the updates from @andydandy74 indicating that this might have been addressed in later exporter versions. Indeed, several similar issues related to geometry export have received fixes in recent Revit and IFC Exporter updates.

We have attempted to reproduce this specific behavior on our side with current versions, but we have not been able to consistently reproduce the issue.

Could you please confirm if you are still experiencing this problem with your current Revit and IFC Exporter versions?

If the issue does still reproduce for you, to help us investigate and resolve this more effectively, please provide:

1. A sample Revit file (.rvt) that consistently exhibits this problematic behavior.
2. Detailed, step-by-step instructions on how to reproduce the issue using your provided file, including any specific settings for the floors, openings, or export configuration that might be relevant.

Providing these details will greatly assist us in identifying the root cause and accelerating a fix.

Thank you for your cooperation!
