Set Point by Distance -- Offset
This function enables you to calculate
a point by using the distance
(chainage) and offset values from a
line. The line is defined by two points.
Enter the first and the second point
of the line or press NEWOC (F5) to
measure new points. Enter the
Distance along the line and the
Perpendicular Distance (Offset).
Enter a negative Distance if the point
lies behind the start point of the line
P1-P2.
Enter a negative Perp. Dist (Offset) if
the point lies on the left hand side of
the line P1-P2.
Instead of entering the values
manually you may calculate them
from two existing points by pressing
INV (F2).
Press COMP (F1) to start the compu-
tation.
Easting, Northing and Height of the
offset point are displayed.
Enter a Point Id, change the Height if
neccessary and press STORE (F1)
will bring you back to the COGO\
Offset menu.
Alternatively press STAKE (F5) to
switch to the stakeout screen and use
the coordinates directly for stakeout.
Input:
P1 - Start point of line (E, N, h)
P2 - End point of line (E, N, h)
d - Distance (Chainage)
o - Offset (Perpendicular Distance)
Output:
P3 - Offset point (E, N, h)
