What is a 'Part'?

MechDesigner definition: A Part is the most basic kinematic-element. Parts move relative to each other. Points in a Part do not move relative to each-other. Joints constrain how Parts move relative to each other.

Kinematic definition: a Part is a Link, a rigid-body, or a solid-body. Any two points within it do not change their relative position.
