Next step Define the reference arc.
7.6.2 Defining the Reference Arc
Description The reference arc can be defined by;
• a center point and start point,
• a start point, end point, and radius, or
• by three points.
All points can be either measured, manually entered, or selected from the memory.

All arcs are defined in a clockwise direction and all calculations are made in two dimen-
sions.
Access Select Ref.Arc and then the method to define the arc by:

Centre Pt Point ID of the center point.
Mid Pt Point ID of the mid point.
End Pt Point ID of the end point.
Radius Radius of the arc.
A positive value, for example 100 m, is for a clockwise direction of the
reference arc. A negative value, for example -100 m, is for an anticlock-
wise direction of the reference arc.
