Description
Current
position to
arc
The direction, distance and coordinate differences between a
known point and a given arc can be calculated depending on
the data available. Points with full coordinate triplets, posi-
tion only points and height only points can be used.
Sufficient information must be known to define an arc.
The coordinates of the known points
•
can be taken from the job.
•
can be measured during the COGO calculation.
•
can be entered.

For all point fields, 3D viewer can be used to select the desired point.
To type in coordinates for a known point, open a selectable list. Press
New to
create a point.
----- is displayed for unavailable information, for example Height difference
cannot be calculated if a position only point is used.
