5.7 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 P1
: The slide distance to the first point.
Pt P2
: The slide distance to the second point.
Azi
: Azimuth between station and extend point.
[MEAS]
: To measure the first or second point.
[VIEW]
: To view the measurement result.
[SAVE]
: Save the extension point.
