Coordinate Systems   

Coordinate Systems

Designer has two types of coordinate systems: the global coordinate system, and relative coordinate systems. The global coordinate system is the fixed, default Designer coordinate system (CS) for each new project. The global CS cannot be edited or deleted. A relative CS is one which you create within the global CS, or within another relative CS. Multiple relative CSs can be created. Each Designer CS possesses an X-axis that lies at a right angle to a Y-axis. The origin (0,0) of each CS is located at the intersection of the x- and y-axes.

A relative CS is user-defined, and its origin and orientation can be set relative to an existing object or relative to another existing CS. Relative CSs enable you to draw objects that are positioned relative to other objects. If you modify a relative CS, all objects drawn in that CS will be affected and all objects will change their relative positions accordingly. You can choose to set a relative CS that is offset from an existing CS, rotated from an existing CS, or both offset and rotated from an existing CS.

You can switch between global and relative CSs by changing the active CS. Objects in the active CS possess a color attribute that overrides the default layer color for objects displayed in the layout editor. User-defined CSs are saved with the active project.
