20. OFFSET MEASUREMENT
Find distance and coordinates of the center of the column.
If circumscription point (P1) and two circumscription points (P2, P3) of a column
can be measured directly, the distance to the center of the column (P0),
coordinates and azimuth angle are calculated and displayed.
• The azimuth angle of the center of the column is 1/2 of total azimuth angle of
circumscription points (P2) and (P3).
