![]() ![]() I suspect that that might be due to the fact that I scaled the curve generated by Gear Generator by the ratio of a line drawn between the midpoint of bottom of the dedendum to the midpoint of a line drawn across the space between addenda (sp?) of adjacent teeth of the curves on the pitch circle. So, for some reason Rhino was unable to join curves. Surface join in progress… Press Esc to cancelġ30 surfaces or polysurfaces joined into one open polysurface. Now I’ve got another issue.Īfter creating the surfaces for one tooth (I used extrude to Point, then trimmed what I didn’t want) and using ArrayPolar, I attempted to join the surfaces. Update: That made all the difference in the world, David. ![]() If that’s the case, I would encourage them to message me about it. ![]() Is that correct? That seems to be a much better approach from a system resources standpoint.īTW, anyone reading this who is about to upgrade their system and would like to sell me their old system, I’ll bet that their old system is better than what I’m using now. I gather from your question that I might have better results by creating the surfaces for one tooth and THEN use ArrayPolar and join those. I then created surfaces for all the teeth at the same time. I then joined the adjacent curves that comprise the profile of one tooth, deleted all the other curves comprising the remaining teeth, selected that joined curve (which is both sides of the dedendum of one tooth and the crown of the appendum of the adjacent tooth) and used ArrayPolar on that tooth the desired number of times about the origin in Top view. I then restored the CP to it’s default by using _4View twice. I had to change the Construction Plane in order to add the fillets of the bevel tooth profile. The surfaces for all the teeth at the same time.Īfter GearGen created the curve, I exploded it to separate the curves of the teeth, and added fillets to the dedendum of a tooth profile in a convenient (along an axis) location. 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.Įdit: I just now tried Surface>Extrude Surface To Point (To Boundary). Rhino is locked up (Not Responding) so I thought I’d take a break for a sanity check. The last thing I saw on the command line was: ‘Splitting… Press Esc to cancel’. I selected the path curve near start ( Solid=Yes DeleteInput=No SubCurve=No SplitAtTangents=No ). I chose Surface>Extrude Curve Along Curve and used the line just drawn as the path along which to extrude to the boundary. 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. 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’ve generated the curve easily enough, but extruding the curve to generate the surface has me wondering. I’ve had success using Thomas Anagnostou’s Gear Generator script to draw spur gears, but drawing a bevel gear has me stumped. ![]()
