In this article, we set one of the horizontal alignments as a reference feature and then tie a component of the default template into this reference feature.

Start the Location Module and follow the below steps.

  • Download the attached folder and open the Example.dsnx file​​.

Two horizontal alignments are already created in the file. The Shoulder alignment displays the left shoulder of the road and the Ditch_CL demonstrates the ditch centerline on the left side of the road. We want to tie the ditch elevation in the template into the Ditch_CL alignment.
