In fact such operations are so complex that can't be solved in a sensible time, and for this reasons CAD packages use approximations that in turn makes most 3D models broken (and generate the occasional crash). Google "Surface-to-surface intersection problem" if you want to learn more about this! :) | |

| Feb 5, 2018 at 13:57 | comment | added | Frames Catherine White | What does it mean to "finalize the booleans into a single object"? (I kinda thought render might be the command to do this, if it is what I think it is) PC Proc is Core2 Duo E6750 2.66Ghz on one computer, and i5-6400 2.70GHz on the other. I think the bools are a problem because they are well known to be slow, they show up in almost every google result about rendering speed in every CAD program. | |
