Methodology Number 1 of 3 | |
| Command: | 1E9 |
| Alpha Alias: | DIS |
| Description: | Defines a distance by point numbers and correction factor |
| Data Format: | 1E9 Point# {Radius-Pt} Point# {Set-Back} Correction (other variations include 2E9 through 8E9 and positive or negative values) |
| Problem: | Given point numbers 1, 2 and 30; set point number 31, from point number 30, at the same distance as between points 1 and 2 as shown below. Then segment the line from 30 to 31 into 3 equal length lines. |
| Solution: | 1 31 30 -2 45 20 12 1E9 1 2 0
-9E9 -3E9 30 31 0
1E9 31 32 0 ; |
Data Description
| Sub-Command | 1E9 | Non repeating sub-command used to compute the straight line distance between any two previously defined points. Used within other commands or sub-commands which request a value for distance. Applies correction factors as described below.
Sub-command 1E9 always computes a positive value. When a negative value is desired, precede the 1E9 sub-command with a minus sign as in -1E9. There are several variations of this sub-command. Use the 1E9 sub-command to recall the distance between previously computed points. Use the 2E9 sub-command to recall the distance and divide by 2. Use the 3E9 sub-command to recall the distance and divide 3, etc., to a maximum of 8E9. This division or segment correction is applied to the final reduced distance. There are no alpha aliases for the 2E9 through the 8E9 sub-commands. |
| Point# | 1 | Previously computed point. A minimum of two point numbers must be entered in the 1E9 sub-command to calculate the distance between them. |
| {Radius-Pt} | | Optional radius point number if you are defining a curve. Append .1 to this number to indicate it as the radius point. This value must be preceded by the Point of Curvature and followed by the Point of Tangency for the curve. See Methodology 2. |
| Point# | 2 | Previously computed point. A minimum of two point numbers must be entered in the 1E9 sub-command to calculate the distance between them. |
| {Set-Back} | | Optional set back distance of the desired length in feet. Add E9 to this value to indicate a set back distance.
Example: Enter 30E9 to indicate a 30-foot set back. See Methodology 3. |
| Correction | 0 | Desired distance correction. If no correction in the computed distance is required, enter 0 (zero). A positive correction will add to the computed distance. A negative value will subtract from the computed distance. |
| No End of
Sub-Command | | No End of SubCommand needed for the 1E9 or the variations. |

Now for some fun stuff!
(or... try documenting this with CAD for posterity!)
Notice that there are only 4 computing commands
that follow.
Intersect a PI holding lines 1-2 and 31-30
3 100 1 1 2 31 31 30 ;
Compute a 30' right of way curve using PI 100
and the distance from 33 to 30 plus 10' for the radius
11 30 10 1 100 30 1e9 30 33 10 0 ;
Now intersect an offset point that is located left
of the line 1 to 2 equal to the radius distance of
the curve minus 10 feet, and right of the line 30 to
100 equal to the distance from 1 to 2
3.1 200 1 1 2 -1e9 10 11 -10 30 30 100 1e9 1 2 0 ;
Now compute a 30' right of way curve using PI 100
and point 200 and the tangent distance from PC 11
to PI 100
11 30 20 1 100 200 0 1e9 11 100 0 ;
With 4 'simple' commands, you have just computed a
wye in a road intersection that is predicated on a
known distance between two points. You can relocate
any point at the top of this file and the entire
alignment and all the radiuses will be recomputed
automatically!

Data Description
| Command | 1E9 | Non repeating sub-command used within other commands or sub-commands to compute the straight line distance between any two previously defined points. Applies correction factors as described below.
Sub-command 1E9 always computes a positive value. When a negative value is desired, precede the 1E9 sub-command with a minus sign as in -1E9. There are several variations of this sub-command. Use the 1E9 sub-command to recall the distance between previously computed points. Use the 2E9 sub-command to recall the distance and divide by 2. Use the 3E9 sub-command to recall the distance and divide 3, etc., to a maximum of 8E9. This division or segment correction is applied to the final reduced distance. |
| Point# | 221 | Previously computed point. A minimum of two point numbers must be entered in the 1E9 sub-command to calculate the distance between them. |
| {Radius-Pt} | 100.1 | Optional radius point number if you are defining a curve. Append .1 to this number to indicate it as the radius point. This value must be preceded by the Point of Curvature and followed by the Point of Tangency for the curve. |
| Point# | 106 | Previously computed point. A minimum of two point numbers must be entered in the 1E9 sub-command to calculate the distance between them. |
| {Set-Back} | | Optional set back distance of the desired length in feet. Add E9 to this value to indicate a set back distance.
Example: Enter 30E9 to indicate a 30-foot set back. See Methodology 3. |
| Correction | -80 | Desired distance correction. If no correction in the computed distance is required, enter 0 (zero). A positive correction will add to the computed distance. A negative value will subtract from the computed distance. |

Sub-Command | | No End of Sub-Command needed for the 1E9 or the variations. |
