The Section Lines tool is a road modeling tool inspired by traditional road survey techniques. This button will drop polylines along an axis. Those lines can be used to generate a lightweight CAD model of the road. 


The Section Lines tool only works on the selected polyline(s) and appears in the TOOLS tab.  



Quick Usage Guide

  1. Select the polyline(s).
  2. Go to the TOOLS tab. 
  3. Set the appropriate Along and Across values in the boxes available in the Create group.
  4. Click on Section Lines button in the same group.
  5. Section lines are drawn along the axis and grouped in a new layer in the project view. 


Tool Settings

Before launching the section lines creation process, set the appropriate Along and Across values.


Along value represents the spacing between two successive section lines along the axis. Determine this value on the basis of your survey requirements and the road topography. In addition to section lines determined by the Along value, other section lines will also be drawn at the vertices of the center line. 


Across value represents the length of the section lines. In other terms it's the width of your survey. To easily determine this value, approximately measure the distance between the center line and the boundary of the area to be surveyed (end of pavement, drain ditch...). Double this distance and use it as Across value.
