I am a total noobie so I apologize up front. My neighbor asked if I could 3D print a part for an old car he is restoring as he can’t find a replacement part. Unfortunately, I had to try to design the part and Sketchup was the only tool I could find to do it in. I believe I have the shape correct but it is hollow and for the LIFE of me, I can’t figure out how to make it a solid. Can someone help?
