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 &RJR , ,QWHUVHFWLRQ .
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 'LVWDQFH or $]P RU %UJ
, 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 6ROYH to compute the intersecting points.
You can view the point’s coordinates by tapping the
5HVXOWV tab and see a graphical representation of
the intersections by tapping the 0DS 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.
