Design Control

The idea of Design Control in LDT exists in Carlson Civil in a number of places.

Template Control – Templates are assigned to centerlines either in the Process Road Design dialog box, or in the Road Profile Editor dialog.
Slope Control – In Carlson Civil, side slopes are actually part of the Template definition.
Ditches – Ditches are defined within the Design Template as part of the cut/fill treatment.

Transitions – There are four methods to work with Transitions in Carlson Civil.

The first is called a Template Series, in which multiple Templates are assigned to a single Centerline at different stations. Next is a Template transition, in which a single Template is assigned to the entire Centerline and the user edits it at different stations. Next is a Template Point Centerline, in which a secondary Centerline is defined and attached to a point on the Template for specific horizontal control, such as a lane widening. Last is a Template Point Profile, in which an additional Profile is defined and attached to a point on the Template for specific vertical control, like the flow line of a ditch.

Superelevations – The template breakpoints for superelevation pivots are defined within Design Template. The stations for the superelevation transitions are set in the Superelevation Editor command.
