User Coordinate System

User Coordinate System(UCS) is a user defined coordinate space. The user can define multiple coordinate systems and store them using Manage User Coordinate Systems. UCS is always defined with reference to WCS. At any given time, there is only one UCS active. The active UCS can be modified using various UCS Tools.

A user coordinate system consists of the following data:

Property Name	Data Type	Description
Name	Text	Name of object.
Xref Dependent	Bool	Whether or not this object is dependent on an external reference.
Xref Resolved	Bool	Whether or not the process with the external reference is successful.
Origin	3D Point	Origin Point for this User coordinate system.
X-Axis Vector	3D Vector	X-axis for this User Coordinate System.
Y-Axis Vector	3D Vector	Y-axis for this User Coordinate System.

To create user coordinate system see the Manage User Coordinate Systems library.
