Pitch circles in a meshing relationship cause the helical gears to be rotated and positioned at an angle of meshing.

Whenever there is a combination of pitch circles touching each other, multiple combinations can be converted to helical gears in a single operation.

The sketch plane for drawing pitch circles is not limited to the XY plane. Pitch circles drawn on any plane can be converted.

Each spur gear is created as a separate component. Therefore, it is possible to set up motion links between helical gears.
