Cartesian Coordinate System

Creo Simulate creates a Cartesian coordinate system as follows:

• Uses the origin and the X axis location to define the X axis.

• Defines the Y axis as perpendicular to the X axis and in the plane defined by the origin, the X axis location, and the Y axis location.

• If the Y axis location is not on a line perpendicular to the X axis, Creo Simulate places the positive Y axis in the direction perpendicular to the X axis that is closest to the location you specified.

The Y axis still lies in the same plane in which you placed it:

The positive Z axis is perpendicular to the XY plane with the positive direction determined by the right-hand rule.

Creo Simulate automatically makes the new coordinate system current.
