Activating a Coordinate System
When you set a User-Defined Coordinate System (UCS) as the active axes, operations such as measuring, transforming a model, or defining a viewpoint are applied with respect to these axes.
- From the Analysis menu, select Set User Coordinate System.
The User Coordinate Systems dialog box appears.
- From the Coordinate System list, select the trihedral coordinate system that you want to use.
- Click Set Active.
- Click OK to close the User Coordinate Systems dialog box.
The newly active trihedral coordinate system appears bolder and larger on the model.
Deleting a User Coordinate System
- From the Analysis menu, select Set User Coordinate System.
The User Coordinate Systems dialog box appears.
- From the Coordinate System list, select the trihedral coordinate system that you want to delete.
- Click Delete.
Note: The UCS disappears from the list.
- Click OK to close the User Coordinate Systems dialog box.
