IFC-Export from Revit 2022 to DeSite

[TKulikovaDCCV2]

Hello, I have a question regarding IFC-Export from Revit 2022 to DeSite (collision detection software). 

After the export of in-placed families I have multiple reports from DeSite, that some of the the exported volumes are not closed. Also, the volumes in Desite are different to those I have in Revit. What could be the cause of this problem?

Thank you in advance

Try adding these settings on in export. Without knowing it, it looks like a volume that your viewer calculates

Thank you for reply!

Unfortunatly, it didn't help. I've tried to export with different property sets, but I still have reports in DeSite that the volume is not closed...
