I think I understand the differences in cache sizes, but I don't understand the differences in geometries and CGAL Polyhedrons -- Sent from: http://forum.openscad.org/

Yes I think that is a clue to the difference in speed but the end result looks the same when shown as a PNG.

I’m on Mac OS Catalina 10.15.7, trying out OpenSCAD snapshot 2020.12.11. I cannot seem to open files into a new tab. My current existing tab always gets replaced by the new file tab. This isn’t making a new window or anything like that. When I do try to open into a new window that works fine. It’s just opening a new file into a new tab that loses the old tab. I see the same tab-replacement behavior when opening scad files from the command-line with the ‘open’ command. - Revar
