Required Step 2

A temporary bounding box is displayed around the picked geometry, and reference points are displayed in the corners of the box and at the center of each face of the box. A UCS is created in the center of this box (the center of the picked geometry). This UCS is orientated according to the active UCS.

If required, pick any point to set a new UCS origin and/or click the point of the arrow to flip it or the base of the arrow to set a new direction.

The following parameters are displayed:
