5.8 LINE & EXTEND ANGLE
The extension function computes extend point
from the base line, calculate the unknown
coordinate from two known points and the
azimuth.
Known:
P1, start point
P2, end point
Azimuth between station C and extend point P
Unknown:
P, Extend point
HA: The current horizontal angle.
VA: The current vertical angle.
Pt 1: The slide distance of P1
Pt 2: The slide distance of P2
Azimuth: Azimuth between station and extend
point.
[Save]: Save the extension point.
