I am trying to fabricate a few parts of my pc using a 3d printer. I was told sketchup was a good software to use. I have watched a few youtube videos, but I’m still not quite sure how to get a cut out to go through a shape. I think I am understanding that using the push/pull tool creates two walls and I’m trying to push one and it stops when it hits the other rather than cutting through it, but I’m not quite sure I understand how to solve the problem yet.
I am essentially trying to create something like the four vertical pieces at the top right of the picture in the link and I can get the top to look right, but I flip the part over to the back and it’s all just flat.
Thanks for any help with my first attempt using the software.
