Hello,
I been using this software for 2 years now and I have never had issues with extruding my objects. But somehow after I was done designing my drawing went to export it to use on a different design and know when you look at the images the look like then been extruded but the are not. Now any new design I try to extrude it’s only pulling up 3 side and leaving the center hollowed out not solid. Can I get some help please.
