5.6.4 Column Offset Measurement

If it is possible to measure circumscription point (P1) of column directly, the distance to the center of the column (P0), coordinate and direction angle can be calculated by measured circumscription points (P2) and (P3).

The direction angle of the center of the column is 1/2 of total direction angle of circumscription points

(P2) and (P3).
