New to Sketchup, I currently am using the pro trial version. I finished making my object, and am ready to export to STL for 3D printing.
I have run into a snag. When trying to use the union tool, it tells me that one or more of the objects is either not a solid or is locked. I downloaded ThomThom’s Solid Inspector 3 and I get the Surface Borders error and it tells me that I have to manually close the mesh.
I’m not sure how to do all of that.
The object is 4 individual objects: the box in the middle, and three domes attached to the sides. I need to join all 4 objects to form one solid object, so I can export to STL for 3D printing.
