Intersection
&RJR ,QWHUVHFWLRQ
The Intersection screen computes, and optionally stores, the
coordinates for the intersection of two lines, where the lines are
tangent to existing points. Each line is independently defined by a
known direction or a known length. (See illustration below.)

Point 1 : is an existing point that is tangent to
the first line.
Point 2 : is an existing point that is tangent to
the second line.

$]P RU %UJ : is the length or
direction, respectively, of the specific line.
;
Store point : When checked, is the point name
used when storing the intersection(s) of the two
lines. If two intersections occur, the second
solution is stored using the next consecutive
point name.
6ROYH : will compute the intersecting point, optionally store the point
and display the information in the Map view.
