To Create a Sketched Coordinate System
When you create a geometry coordinate system in a sketch-based feature, the new coordinate system exists as a regular coordinate system in the Standard application. Using a geometry coordinate system is the only way that a coordinate system created in Sketcher can convey feature-level information outside of Sketcher.
1. Click >
