Coordinate System, Work Coordinate System
Work Coordinate System (WCS) is used to facilitate the construction of geometry in different orientations.
WCS can be manually located and oriented anywhere in model space. WCS is what we will use for construction if we want to determine the orientation and angle features. Axis of the WCS are marked XC, YC, and ZC.
It is possible to have several coordinate systems in the file, but only one can be the work coordinate system (WCS).
