I saved my Archicad file as dwg format and imported it in sketchup.
It work perfectly.
but when I push the render button of Vray for sketchup it always get the error message and my vray dont work.
The vray for sketchup works good when I import the dwg file which exported form "Revit".
I prefer Archicad so I wish the Archicad files work nicely with Vray for Sketchup.
Anybody who knows how to solve this problem answer me, Thanks.
