Hi eric, SketchUp models are made up of polygons only so that's why there is no .skp format import for MoI and only an exporter.

Try using Rhino though, I think it has an importer with an option to convert large planes with holes in it into trimmed surfaces.

Thanks Michael and Pilou ..

Michael .. yes, importing into Rhino as trimmed surfaces worked well.

cheers,
eric
