markschum, thanks for the box. I get the same result. No parts and no surface. May I ask about the surface? The obj includes the surface names, as "usemtl ...". Does modeling software interpret this as:

• "make that surface"

or does it interpret it as - "search for the xxx.mtl file and read the values out of that one"?

Anyhow I will now go back to another LW version and try with that one.
