Normal Module Involute Helical Gear in CATIA V5 (manual input)

This BND TechSource video shows the steps for creating a “template” part for our Normal Module Involute Helical Gear.

This part may be modified by simply changing the parameters of any/all of the following five formulae:
Fw - Face width // length parameter [Fw = input]
z - number of teeth // real parameter [z = input]
Npa - Normal Pressure Angle // angle parameter [Npa = input]
m - module // length parameter [m = input]
Ca - Cylinder helix angle // angle parameter [Ca = input]
