4. Check the Store Pt 1 checkbox and specify a point number in the
same field if you want the endpoint of the computed line to be
stored.
5. Enter the direction of the left side of the boundary in the last
field. In this example, you should use the power button, and
select Choose from map… and then tap points 2 and 1. The
direction from point 2 to point 1 will then be automatically
entered in the last field.
6. Tap Solve. The final boundary side will be computed and the
data can be viewed by using the Results and Map tabs. If you
selected to store a point in Step 4, the computed point will also be
stored.
Parallel Method
The Parallel Method computes the location of one side of a four-sided
boundary where the computed side is parallel to a stationary side of
the boundary.
Using the same lot as we used above, we will compute the location of
a line in a 1/3-acre boundary that is parallel to line 2-3 and intersects
with line 2-1 and 3-4 as shown here.
1. Tap Cogo , Predetermined Area from the Main Menu.
2. In the upper-left corner, enter the desired
area (1/3 acre in this example) and select
the Parallel radio button.
3. Enter the first point that defines the fixed
side of your four-sided boundary in the
Point 1
field and the second point in the
Point 2
field. (The computed side will be
parallel to the line between these points.)
4. Define the directions of the two sides of the
boundary that will intersect with the
endpoints of the computed line. For this
example, you would tap the power button,
associated with each direction, select Choose From Map… and
then tap points 2 and 1 for the first direction, and 3 and 4 for the
second direction.
