This is bit of a solid modeling or inspection question, which way do you model gears/worms for the most accurate output? We are outputting gears for CMM inspection programs and I am a little confused in my typical modeling style as to which way would produce a more accurate gear profile for inspection. Do you model the gear profile parallel/perpendicular with the cylinder axis or do you use a plane to draw the profile perpendicular to your line of helix before using a cut-sweep to remove material from the main body.
I'm having a brain-fart or logical argument issue either way, any insight would be helpful.
