By Three Points
To place the ruler or grid by three points:
1. Enter CS_SET.
2. Pick the origin, a point on the x-axis, and a point on the y-axis.
This option changes the axes orientation relative to the current orientation (this may not be the same as the original orientation). To place the ruler or grid by relative orientation:
1. Enter CS_SET RELATIVE.
2. Pick two points that coincide with the new x-axis of the ruler.
Creo Elements/Direct 2D Access changes the cross-hairs to the new orientation.
