How do I make the circular cuts be perpendicular to the surface? As an example, the cuts shown by 'cut-extrude38' tend to be a top plane view extruded cut directly downwards. I need the cuts to be perpendicular to the surface rather than the top plane. I tried using the hole wizard and dimension the hole on the surface but it won't let me dimension it due to various problems. Additionally, I tried projecting the cut onto the surface but that also caused errors. Any help would greatly be appreciated.
