I must be doing something fundamentally wrong. On the attached model, no matter what I do, I cannot make the very small extrusions, (holes), penetrate all the way through the side plates. Frustratingly, I managed to achieve it one plate, but cannot remember how I went about it!
In addition, where I have placed the text, the rectangular shape with a rounded end should be a recess, but no matter what I try, it just won’t happen. Boolean difference and make a hole are what I have tried.
Have I gone about modelling the whole thing incorrectly. HULL - Copy (2).3dm (10.1 MB)
Any help would be appreciated please.
