GearTrax acts as a bridge between engineering theory and 3D modeling. It supports a wide array of drive components, including:

Note: Geartrax does not work with SolidWorks Student Edition due to API restrictions.

Unlike generic gears, splines require specific fits (flat root, fillet root). GearTrax 2022 supports ANSI B92.1, DIN 5480, and JIS B1603 standards for spline shafts and hubs.
