Divided Crown Superelevation in Civil 3D
11/19/2025
Paul Storm, a Micrographics Solutions tech, continues his study of how to produce a Divided Crown Roadway design with Superelevation in Civil 3D.
The video includes a quick review of a corrected Assembly (which includes a Marked Point subassembly) and a pair of divided crown two lane roads with paved shoulders.
The core steps of the Superelevation Wizard and the basics of Civil 3D Superelevation Views are also covered.

The AASHTO tables and superelevation values produced by the Superelevation Wizard and employed here work for most 2 and 4 lane Divided Crown highways in most US States.
Use of the appropriate Design Criteria file is also required for passable and acceptable production results.
Note that the reviewed Assembly includes a Marked Point subassembly in the first resolved Group and the proper type of Superelevation and setting values are employed here.
Here's a link to the previous webinar video in the series.

Here's a link to a video from the cadpilot site that addresses the issues and fixes above.
This example from a Jump Kit Sandbox Project dataset and the Templates Only Example Corridors drawing employs slope controlled Offset Profiles but any other design control can be employed for the targeting.
