About Standard Point Codes for Subassemblies

A set of standard codes define the display and behavior of the point components used in the Autodesk Civil 3D Corridor Modeling subassemblies.

The following illustration shows the location of the standard point codes on subassemblies defining a divided road with a depressed central reserve and truncated shoulders.

Divided Road with Depressed Central Reserve; Truncated Shoulders

The table following the illustrations provides descriptions of the point codes used in the illustrated assemblies.

The following illustration shows the location of the standard point codes on subassemblies defining a divided road with a depressed central reserve and extended shoulders:

Divided Road with Depressed Central Reserve; Extended Shoulders

The following illustration shows the location of the standard point codes on subassemblies defining an undivided road with a kerb-and-drainage channel. Not all layers are shown.

The table below names and describes the standard point codes used in the example assembly illustrations.
