Modeling in Space
Different approaches
Modeling in assembled position
Often using the same datums for tooling and other purposes (coordinated datums)
Modeling without regard to assembled position
A Mixture of the two
Coordinate Systems
Absolute Coordinate System (ABS in NX)
Work Coordinate System (WCS in NX)
Feature Coordinate Systems
Right Hand Rule
Manipulating the WCS
WCS Dynamics
