Solid extrusion not showing on export

I have created a series of paths in autocad, which I then import into rhino and created a solid extrusion. I then need to export this into sketchup, however on doing so, the extruded surfaces don’t appear in sketchup and instead its just the frame of the extrusion. I recall doing this last year and it worked fine, so I’m not sure what I am doing wrong

thanks

Can you try the ConvertExtrusion command on the extrusion in Rhino prior to exporting as skp? I’m wondering if the extrusion object lightweight render mesh is involved. This command will make polysurfaces from your extrusion objects.

Any luck?

that seemed to do it!

thanks
