This is another one of those topics where I’m surprised I haven’t covered it yet. I’ll be showing you how to cut perfectly circular holes (or perfectly ‘any-shaped’ holes) into a turbosmoothed mesh. It’s less focused on keeping tight geometry, and more focused on the basic idea.
We start by taking a spline shape (in this case a circle) and using the cut tool and snaps toggle (with ‘vertex’ enabled) and we cut the circular hole into the target polygon. Once that’s done, it’s up to you what you want to do with the shape!
P.S. I’m stoked by all the comments people are leaving! Thanks for letting me know what you think, and I’m open to more ideas for Monday Movies!
