Relationship from Master String to 3D Polyline

 Previous pageReturn to chapter overviewNext page

Purpose

To write a file to illustrate the "near and far" plan distances between a Master String and a 3D Polyline.

Horizontal alignment (white) and 3D Polyline (cyan)

Horizontal alignment (white) and 3D Polyline (cyan)

 

Operation

Pick the 2D Polyline representing the Horizontal Alignment and select the .vtg file.  

Pick the existing 3D Polyline and the dialogue appears :-

 

For typical use the start and end chainages are fixed by the start and end of the 3D Polyline assuming the Master String is longer

The top of the .kdr report file looks like this with the first line in the pair the Master String and the second the 3D Polyline :-

The bottom of the .kdr report file is sorted in offset order to show looks like this with the first line in the pair the Master String and the second the 3D Polyline :-
