I am generating a face crown gear tooth profile using Grasshopper. The tooth profile is being generated by a loop function that repeats a solid difference command after rotating the crown and pinion each step.
The result looks like this:
I would like to export this solid to Solidworks. Before I export however I would like to create a smooth nurb (?) surface to replace the stepwise result of my solid difference operations.
This surface is pretty processor intensive:
I would like it to be like this (this is an example of a different crown gear):
At first sight it seems to me that should not be very difficult but after hours of trying I just can’t get it to work… but that is probably because I am a Solidworks user with limited Rhino and Grasshopper experience. So the solution can be a Rhino operation and does not necessarily have to be a Grasshopper thing. Although of course that would also be very cool.
I have attached the Rhino file that contains the baked crown gear

For anyone interested I have also attached the Grasshopper code for creating a pinion face gear pair. There are several extremely expensive software suites out there, but after a little coding it seems to be that this (not very tidy script) does the trick.

I would be so grateful if there’s anyone out there that can help me out.
