Intersection: Distance - Distance
This function enables you to calculate
the intersection point(s) of two circles.
The circles are defined by a the
centre point and the radius.
Enter the point 1 of the first circle or
press NEWOC (F5) to measure a
new point. Enter the optional Parallel
Offset and the radius (Distance).
Enter the values for the second circle.
Instead of entering the values manu-
ally you may calculate them from two
existing points by pressing INV (F2).
Press COMP (F1) to start the
computation.
Easting, Northing and Height of the
first intersection point are displayed.
The first intersection point is the point
left of the line P1-P2. To display the
second intersection point press
OTHER (F3).
Enter a Point Id, change the Height if
neccessary and press STORE (F1)
will bring you back to the COGO\
Intersection menu.
Alternatively press STAKE (F5) to
switch to the stakeout screen and use
the coordinates directly for stakeout.
Input:
P1 - Centre point of 1. circle (E, N, h)
r1 - Radius
P2 - Centre point of 2. circle (E, N, h)
r2 - Radius
Output:
P3 - 1. Intersection point (E, N, h)
P4 - 2. Intersection point (E, N, h)
