I sometimes design parts that will be converted to stl file and 3D printed. The 3dm model needs to be "water tight" with no naked edges before exportng as a stl file.
I'm designing a part with holes in it. The edges of the hole need to be chamfered. When I chamfer the surfaces I end up with naked edges at the chamfers. Repairing them works in some instances but some can't be repaired.
Am I doing something wrong that causes this? Are there any tricks that will avoid the naked edges?
Any insight or advice would be appreciated!
