Ifc Export Problem - RVT2023, IfcSlab, IfcSite

[andras.horvathEHM2D]

Dear Group

I have a problem since long time, that IfcSlab and IfcSite will not exported from my modell.

I set the export settigs, I adjusted Floors to  IfcSlab, and my Topografie to IfcSite. But if I export my Flor and Topo, it will be not in my IFC. Thats mean for me, the Export in IFC "By Categorie" doesnt work in the case of Slabs and Topos.

If I set the "Export in IFC" to "yes", it will be es

exported. But I have to set it for all of the slabs... And I dont understand why by categorie doesnt work. 

This problem is only if I work with my laptop. With my desktop pc, it works with the same settings. (Asus TUF A15)

Another Question is, I have a Linked Topografie in the Modell. But It will be not Exported, and it do not have the Parameters I want  (IfcDescription). But I can parametrise the under regions of a topografie, but in case I got always IfcBuildingProxy and not IfcSite...

I would be very happy, if you could help me.

Thank you in advance.

Dear Andras,

It is unclear for me from your question whether you are programming anything yourself.

If not, you might get more help in one of the non-programming forums:

If you are programming yourself, you will find more expertise on IFC-related issues in the IFC discussion forum:

• https://sourceforge.net/p/ifcexporter/discussion/general

I hope this helps one little step forward...

Cheers
