I’ve had success using Thomas Anagnostou’s Gear Generator script to draw spur gears, but drawing a bevel gear has me stumped. I’ve generated the curve easily enough, but extruding the curve to generate the surface has me wondering. Maybe it’s this slow machine that doesn’t allow the object to be drawn in what seems to me to be a reasonable amount of time.
I generated a surface using sweep 2 rails above the curve to serve as a boundary to extrude the curve to and an angled line to serve as a path from the quad of the pitch circle through 135 deg to the Z axis intercept. I chose Surface>Extrude Curve Along Curve and used the line just drawn as the path along which to extrude to the boundary. I selected the path curve near start ( Solid=Yes DeleteInput=No SubCurve=No SplitAtTangents=No ). The last thing I saw on the command line was: ‘Splitting… Press Esc to cancel’. Rhino is locked up (Not Responding) so I thought I’d take a break for a sanity check. Is there a better way to draw a bevel gear? I saw Ian’s post about A new involute gear generator but I think I’ll try to get Gear Generator figured out first.
Thanks in advance.
Edit: I just now tried Surface>Extrude Surface To Point (To Boundary). That seems to work much better.
