The profile of a standard gear is controlled by a sets of equation. Once the input parameters are defined, the profile can be generated automatically based on a macro (a sets of equations) or the system will recall the already-drawn 3D/2D file from its library. Many value-added resellers know how.
Nx & catia is a plm complete solution, not just a cad, which include cad, cam, cae, pdm & a collaboration platform. They are the best in developing complicated & new designs. "Drawing" is not just their main focus, because they know they can draw. They focus on how to build the best design in the best way.
