Hey everyone. I’m really new to SketchUp. I’m really into it and have been using it for 3D printing. I have a project where I’m going to use some threaded rod to drive the below gear. The gear below is exactly what I need. All I have to do is punch a hexagon shape hole in the center so that I can place a threaded nut in there. But that’s the problem, this is an imported STL file and it’s not acting like any other design I’ve created in SketchUp.
I cannot figure out how to punch a hole through this design. Any help would be greatly appreciated.
