I’ve followed a rapid tutorial for building 3D models with SketchUp. I’m able to make, save, edit a simple 3D model. But this doesn’t seem enough to edit the .skp files the Helios4 team published for the Helios4 Mini-Case (link).
All I want is to adjust them for the Raspberry Pi dimensions. But it seems that I can’t edit (move/delete holes, make circles, rectangles, …).
Do you have any idea why?
Can you tell me how to edit those?
