Hi @ryanhillier38
It seems that objects made from the picture frame material in R6 can’t easily be converted to “ordinary” geometry. The best offer from this thread is to export the geometries as Rhino V2 via export and then re-importing them. I can’t believe there isn’t a better way, @pascal?
At least, it looks as if exporting and re-importing works 
Some of the geometries are a bit messy with lots of small, narrow faces - but all are valid polysurfaces.
