Inverse Point - Current Position

The direction, the distance and the coordinate differences between the two known points can
be calculated depending on the data available for the known points. Points with full coordi-
nate triplets, position only points and height only points can be used.
Elements that must be known are
• coordinates of two points.
The coordinates of the known points
• may be taken from the active job.
• may be manually occupied during the COGO calculation.
• may be entered.
