How did you all get it to compile? When I compile it, I get these errors WARNING: Ignoring unknown module 'alesage' in file test_bug_fix.scad, line 55 <55,/Users/kdt0p/Desktop/test_bug_fix.scad> WARNING: Ignoring unknown module 'ContreAlesage' in file test_bug_fix.scad, line 61 <61,/Users/kdt0p/Desktop/test_bug_fix.scad> WARNING: Ignoring unknown module 'alesage' in file test_bug_fix.scad, line 62 <62,/Users/kdt0p/Desktop/test_bug_fix.scad> WARNING: Ignoring unknown module 'alesage' in file test_bug_fix.scad, line 73 <73,/Users/kdt0p/Desktop/test_bug_fix.scad> WARNING: Ignoring unknown module 'ContreAlesage' in file test_bug_fix.scad, line 79 <79,/Users/kdt0p/Desktop/test_bug_fix.scad> WARNING: Ignoring unknown module 'alesage' in file test_bug_fix.scad, line 80 <80,/Users/kdt0p/Desktop/test_bug_fix.scad> Compiling design (CSG Products generation)... I had to comment out the line " //$fn=120;" or it made my system hang or at least go slow enough that I gave up, with an F5.
