Creates AutoCAD® Civil 3D® objects for the grading model. A Civil 3D surface can be specified and the grading model's initial elevations set to those of the surface. You can also generate Civil 3D alignments and a top surface for the grading model. Using Civil 3D tools, a corridor can be created using the Civil 3D alignments (including curb & gutter, sidewalk, daylight, etc.) and it can be set to update when the grading model is updated.

Note: This dialog box is only available when TORUS is run within AutoCAD Civil 3D.

Specify the name that is used to associate the Civil 3D grading objects with the current grading model. The grading model's Civil 3D top surface is created using the specified name. The specified name is used as a prefix for creating the Civil 3D alignments.

Generate Civil 3D Grading Objects Section

These buttons allow the Civil 3D grading objects to be created and deleted. When the respective Civil 3D grading objects have not been created yet, the buttons in this section display "Generate" in their names. After the respective Civil 3D grading objects have been created they display "Delete" in their names.

Option	Click to...
Generate Civil 3D Alignments	Generate the corner, crown, ICD, central island, and truck apron grading model alignments as Civil 3D alignments.
Generate Civil 3D Corridor	Generate a Civil 3D corridor from the roundabout and assemblies. The default Civil 3D assemblies can then be edited using AutoCAD Civil 3D tools to customize the corridor.
