About Space Reference System Assistant

Space Reference System Assistant helps you manage the current space reference system.

The Space Reference System Assistant panel consists of the following options:

Current Space Reference System
Lists the reference plane systems assigned to the Common Geometry Reference and Secondary Geometry References resources in the Data Setup.

The selected reference plane system becomes the current one. It is later used as a reference for modifying 3D grid and measuring space coordinates.

Space Coordinates
Provides coordinates of a point with respect to the current reference plane system.
Important: If the Space Coordinates check box is not selected and you measure the point using the Measure Item command, the selected point is measured in absolute coordinates.
