I have an STL file of part of an airway, it’s a fairly complex biological shape but I’ve reduced the triangle count significantly to keep it manageable. I would like to be able to apply a pattern of circular holes to its surface (like a simple polka dot pattern of 2mm holes), but don’t know enough about Rhino to know if that is even possible. I know it is somewhat limited when it comes to modifying STL files. I can manually add a mesh cylinder, manually position it, and then do a boolean subtract operation to cut holes into this thing one at a time, but I am in need of a more automated way of doing this. Does anyone have any ideas as to how I can go about doing that? Is there any other software that might be better?
I’ve attached the STL file of the part, as well as an STL of just the outer surface in case it’s better to work with just that. Thanks in advance, much appreciated!
