Hi Paul, so I looked over your screenshots again and I think I see your problem - I didn't notice before but it looks like in your screenshot your geometry that was loaded consists entirely of curves and not any surfaces.

Is that correct?


If so then that's your actual problem - in order to write to a mesh file format like LWO or OBJ, you have to have surface data and not only wireframe curve data in the model.


One way you can test this is to try opening the attached sphere.3dm file and then do a Save As to LWO or OBJ formats - does that seem to work ok?
