To Create a Coordinate System
1. Click > . The Coordinate System dialog box opens.
2. Select up to three placement references in the graphics window. References can be surfaces, planes, edges, axes, curves, datum points, vertices, or a coordinate system.
3. Click OK to create the new coordinate system with the default orientation, or click the Orientation tab to orient the new coordinate system.
| If you have selected a vertex as an origin reference, a default orientation is not provided, and you must manually orient your coordinate system. |
