Hi Jessesn, thanks for your answer! Sometimes Sub-select works, but often it just gives me an edge - see pic.
Enclosed a file with just one bevel gear … and maybe there is the cause of the problem: this file with just one gear has 14.7 MB … that seems very much for a small gear to me. It is generated online on evolventdesign.com. I also tried the gear plugin for Rhino, but I can’t get it installed in Rhino 7 Mac.
bevel gear test.3dm (14.1 MB)
Best regards - Jan
