This example shows how to create a screw mechanical mate.

// --------------------------------------------------------------------------------
// Preconditions:
// 1. Open public_documents\samples\tutorial\api\MechanicalMates\Gearbox.sldasm.
// 2. Delete Screw2 from the Mates folder of the FeatureManager design tree.
// Postconditions: Inspect the Mates folder in the FeatureManager design tree.
// NOTE: Because the model is used elsewhere, do not save changes.
