Gears are modeled as full mathematical involutes. Design spur gears, escapements, ratchets, elliptical gears, heck design gears with arbitrary shapes that were imaginary, until you create them.

Seriously cool features like point and click spoke design with hundreds of spoke patterns.

2 1/2D machining and 4th axis machining of gears. Not all gear types support 4th axis if their tooth model isn't compatible with tangential machining.
