IFC Export option failed

I tried to assign a specific ifc class to a layer (ifc export option) but when I export .ifc file in a bim viewer the ifc class remain a default value (e.g. ifcbuildingelementproxy).
Thank you in advance

Hi @fn_a, can you share the 3dm and ifc file you are generating? (you can send them to visualarq@asuni.com) if you like.
Which versions of Rhino and VisualARQ are you using?

Hi @fsalla,
here you are the file
Rhino 7.6.21127.19001
test impianto elettrico.rar (4.1 MB)

The “By Layer” option is missing for Element objects, in the IfcTag Properties dialog. For that reason, it’s not taking the value assigned in the IFC Export Options dialog. You will need to assign it from the properties panel, in the meantime.

Thank you @fsalla,
I hope you add this feature to the wish list
