Intersection
The Intersection screen computes and optionally stores the
coordinates for the intersection of two lines that are tangent to
existing points.
Each line is independently defined by a known direction or a known
length. In the situation where there is more than one possible
solution, each solution is provided and optionally stored.
1. From the Main Menu, select . Cogo ,
Intersection .
2. In the Point 1 field, enter the point name
that is tangent to the first line that
intersects with the other line.
3. Toggle the first button to Distance or
Azm or Brg , depending on if the first line
intersects at a known distance from Point 1,
or at a known direction from Point 1,
respectively.
4. In the same way that you defined the first line, define the second
line tangent to Point 2 in the Second Point section of the screen.
5. If you want to store the intersecting point(s) that are computed
from the routine, check the Store Points checkbox and specify a
point name in the same field. If there is more than one solution,
the additional points will be stored with the next sequential point
name.
6. Tap Solve to compute the intersecting points.
You can view the point’s coordinates by tapping the
Results tab and see a graphical representation of
the intersections by tapping the Map tab.
The map shown here illustrates a situation where two
intersections were computed from a line with a known
length tangent to Point 1 and a line with a known
direction tangent to Point 2.
