Set Road Cross Sections Define global or per-vertex road cross sectional shapes

Set Surface Road Cross Sections

To access this dialog:

• Using the Create Surface Roads task, generate or select a centerline and, in the Road Parameters control group, select a cross section library and click Edit Points.

The Edit points button displays the Set Road Cross Sections dialog allowing you to select points along the road reference line and assign specific cross sectional shapes to them.

You can assign either a crown or edge (cut or fill) section to selected reference line points in the 3D window. Your road reference line should be visible before you start to use this dialog (you can enable it using the Surface Roads Toolbar).

This dialog works in conjunction with any Default crown and/or edge profile shapes set in the parent Create Surface Roads task.

The Set Road Cross Sections dialog is not required if you wish to apply the same crown and edge profiles to the entire road. In the absence of any per-reference-line-point section settings, the default values will be applied throughout the road when Generate Road is selected.

 

The checkboxes on the left control which values are written to the road reference line points. In addition to the named cross sections, points may be reset to tracking the default cross section IDs, by using the <default> option.

Assigning Cross Sectional Shapes to Centerline Points

Road cross section shapes are assigned to road centerline points by:

1. Displaying the road reference line.
2. Selecting the crown and or edge shapes to be applied to reference line points.
3. Selecting the reference line points to be modified. Points may be selected using the click or box drag mechanism, supporting the use of the <CTRL> key to extend or toggle the existing selection.
   
   Selected (but unchanged) points will be highlighted in red e.g.:
   
   
   
4. Clicking Apply to Selected Points. Modified points will be highlighted in green, e.g.:
   
   
   
   This will append the reference line string object with section ID information.
   
5. Clicking Close to return to the Create Surface Roads dialog.
6. Clicking Generate Road to (re)create the specified output objects.
