change.)
Simple Angle : when selected, this allows you to
enter the deflection angle to rotate the selected points.
Old and New Azimuths : when selected, this allows you to enter an old
and new azimuth, which is used to compute the angle to rotate the

Rotate : is the angle to rotate the selected points around the Rotation
point .
2OG $]LPXWK / 2OG %HDULQJ : is a known direction between any two
points in the current job before they are rotated.
1HZ $]LPXWK
/
1HZ %HDULQJ : is the direction between the same
two points specified above after the rotation.
6ROYH : will perform the rotation on the selected points and change
