| Command: | 1 |
| Alpha Alias: | Locate Dir |
| Description: | Computes consecutive points by bearing and distance |
| Data Format: | 1 Set From Bearing Distance {[Bearing Distance] ...}; |
| Problem: | Given point 20 found on a line bearing North 65°06'50" East, set point 21 at a distance of 85.4 feet. Set point 22 from 21 in direction of South 73°24'12'' East at a distance of 75 feet. |
| Solution: |
1 21 20 -1 65 6 50 85.4 -2 73 24 12 75.0 ; |
Data Description
Command
| 1
(or Locate Dir)
| Computes points by bearing and distance from an existing point. Computes and stores each pair of coordinates and their point number as the command processes.
Continuously computes points using the last computed point and a new bearing and distance.
|
Set
| 21
| Point number to be assigned to the first set of coordinates you want to compute.
|
From
| 20
| Previously stored point number from which the coordinates are to be computed.
|
Bearing
| -1 65 6 50
| Direction of the line on which the point is to be computed. Bearings may be entered using point definition.
|
Distance
| 85.4
| length of the line from the known point to the point which is to be computed.
|
{[Bearing
Distance]...}
| -2 73 24 12
75.0
| Repeating feature of this command. Subsequent points will be set from the last point computed and based on the bearing and distance specified. The subsequent point numbers are automatically assigned and ordered as designated by the Set point. If the Set point is entered as a positive number, the subsequent points will be numbered in increasing order. If you enter a negative number, the following points will be numbered in decreasing order.
