Creating the Road Centerline

The road design elements can be created on a separate layer to facilitate modifications later.

To create the road centerline:

If desired, create a new layer for the road by selecting Tools > Organization. The layer scale should be the same as the site model layer scale. Set the site model layer to visible, and select View > Layer Options > Show/Snap Others.
Using the Polyline tool, create a polyline that represents the road shape.

For more information on polylines, see Creating Polylines.

Interior vertices of the polyline must be arc-smoothed (no Bézier or cubic vertices).

Smooth vertices with the Modify > Poly Smoothing > Arc Smoothing command.

The road must be contained within the site model grade limits.
