Group: |
32) Station Os Tan |
Methodology | |
| Command: | 33 |
| Alpha Alias: | List PlusOsTan |
| Description: | Prints offset distances perpendicular to any tangent and station values from the initial point |
| Data Format: | 33 From To Point# {[Point#].. } ; |
| Problem: | Given a computed centerline tangent alignment. Compute plus and offsets to points along the tangent from the initial point. |
| Solution: | 33 7 11 139 -142 ; |
Data Description
| Command | 33 | Prints plus and offset distances to specified points along a given tangent.
The 33 command is typically used to check the offset distances from objects such as fence posts or iron pipes, etc., to a computed property line. Note: Previous versions of iPOGO used a -1 flag to repeat the 33 command for the next tangent sequence. This created a situation where point ranges could not be implemented in the older versions. This version of iPOGO does not support the -1 flag for repeating tangent sections since it is easier to start a new 33 command. This allows iPOGO to now support point ranges in the 33 command. Since the 33 command calculates plus values and not stations, the 300 command for continuation of alignment stationing has not been implemented here. All old command files should be modified correctly when imported by iPOGO, but should be verified by the user for accurate conversion to the new version. In addition, prior versions of iPOGO implemented the 33 command as 33,1. The ,1 served no purpose and has been dropped from this version. |
| From | 7 | Number of the initial point on the tangent. |
| To | 11 | Number of the endpoint on the tangent. |
| Point#
{[Point#].. } | 139, -142 | Points near the tangent line to compute plus and offset distance values. |
| End Command | ; | All commands end with a semi-colon. |
