Design Accelerator still provides 2 types of models but all of them are simplified. The first one has simplified the tooth profile and the second one is just a simple shape representation that we call 2D.

Are you looking for an exact tooth profile or just visual effect like approximate curve would help?
A better approximation is what I was referring to. If you take a look at the attached sample, you will see relatively large regions of interference.
I've used single arc approximations for involute gearing and splines for many years. It is amazing how little variation there is between a simple arc and an involute profile. I was thinking that utilizing arcs for generation of the worm gear profile would provide similar results - "a lot of bang for the buck"
