The road design elements can be created on a separate layer to facilitate modifications later.
To create the road centerline:
1. 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.
2. Click the tool and create a polyline that represents the road shape.
For more information on polylines, see Criando Polilinhas.
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.
