Three-dimensional bodies processing method for computer-aided-design system, involves describing position of each body in global coordinate system through position description of local coordinate system with respect to global system

摘要

The method involves determining a local coordinate system for each body (A, B, C), and setting the origin of the local coordinate system in the geometric balance point of the bodies. Coordination axes (X, Y, Z) of the local coordinate system orient to main inertia axes. The position of each body in a global coordinate system is described through the position description of the local coordinate system with respect to the global coordinate system.
