I’ve run into a minor wall when it comes to cutting holes in things in Blender. I want to make a hole in the side of a cylinder, like a note hole on a flute, for instance. When I try, however, I get outward deformation, like this:
Those screenshots were taken of an 8-sided cylinder using 3 layers of subsurf. The hole was simply where I deleted a single face from the side. I’ve tried creasing and sharpening the edge with an edge split modifier and Mark Sharp, but neither seem to stop the deformation. Any movement of the adjacent vertices or edges just results in more deformation. I just want the roundness of the cylinder to continue uninterrupted, just with a hole in it. Does anyone know how to do this?
