Re: Cylinder mock-ups of gears in Inventor?

Another tip, stack two cylinders on top of each other. one with the pitch diameter and one with the outside diameter of the gear. that way you can still check for interferences with other parts. The formulae:

OD = (N+2)/DP
PD = N/DP

OD = outside diameter
N = number of teeth
DP = Diametral Pitch
PD = Pitch Diameter
