It is possible to create a site plan quite quickly by exporting a Location design into the Terrain module. However, there are some limitations as illustrated in the example below.

This example can be done using these example files:

1. Create a location design of the bridge section. (see bridge.dsnx)

  • Make sure the abutment elevations are correct
  • Choose appropriate grades, and curves
  • Assign the Bridge (no cut/fill) template to the bridge station range.
