Thanks for the advice. I think I’m going to need to start from scratch on this project. I basically have 2 squares; say one 2cm and one 3cm. They are 5 cm apart facing each other. I was trying to wrap them to create a rectangular solid shape and then fillet the 5cm corners. I managed to do this but it is not a solid shape and therefore I can’t do any boolean operations on it. I can easily extrude a 3D rectangle but then I am not able to change the sizes of the individual squares unless I explode the shape, but then nothing is connected any more.
If there is a tutorial that I should have watched that covers this, please let me know where I should be studying.
