That solved the problem Michael. My object was converted from Solidworks to STL first, then imported to MOI. It came in without surfaces, probably lost during the first conversion. I didn't notice because modo, my main 3d app, often displays just in wire mesh view. I realize curves with out surfaces is a different situation. I was able to save out the Sphere you sent in all the formats with mesh options included.

Thanks, for sticking with me on this and seeing it through. This must be a good forum.
