I’ve been using the Drilling operation for the first time, and it didn’t seem to work. I tried changing every setting I could find that might affect it, but the best I managed was to just mark the surface. Then I checked the Marking box, and it drilled the hole! Is it me, or are the Marking options reversed, so you have to check it to drill a hole?
marking matches all holes regardless of diameter. when unchecked, the drill operation matches holes to the diameter of the working tool. depending on how faceted the part when exported from CAD, it may not match in some cases.
