To continue this tutorial, go to Exercise 2: Creating Corridor Surface Boundaries.GD&T Guide Geometric Dimensioning and Tolerancing The corridor from which the surface was taken is listed in the surface properties definition.

When a corridor is rebuilt, corridor surfaces are updated to reflect any changes in the corridor, and then any edits are applied to the corridor model.

When you change the surface style of a corridor surface using its surface properties, the style is also changed in the Corridor Properties dialog box on the Surfaces tab.

The corridor it is based on is not selected.

When you select a corridor surface, only the surface is selected.

The following features and behaviors are unique to corridor surfaces:

You can work with a corridor surface the same way you do with any surface in the Surfaces collection, including changing its style, adding labels to it, and using it for surface analysis. Notice that the corridor surfaces you created have been added to the Surfaces collection.

In Toolspace, on the Prospector tab, expand the Surfaces collection.

Click OK to create the surfaces and close the Corridor Surfaces dialog box.

Generate the surfaces and examine the results

Repeat the previous procedure to create a Datum surface, using these parameters:

DATUM SURFACE CODE

This action adds the corridor links with the Top code to this surface. This setting is especially critical when an assembly has overlapping subassembly links that, if connected, would result in errors in surface triangulation. This setting specifies that the surface will be built using the links along the top of the assembly.

Change the Overhang Correction setting to Top Links.

Select the Corridor - (1) Top surface by clicking the icon next to its name.

In the Pick Render Material dialog box, select Sitework.Paving - Surfacing.

Click the Render Material cell for the Corridor - (1) Top surface.

In the Pick Corridor Surface Style dialog box, select Border & Contours.

Click the Surface Style cell for the Corridor - (1) Top surface.

Change the surface name to Corridor - (1) Top.

In the Corridor Surfaces dialog box, click Create A Corridor Surface to create an entry in the surfaces table.

Click Corridor tab Modify Corridor panel Corridor Surfaces Find.

Open Corridor-5a.dwg, which is available in the tutorials drawings folder.

The Median surface defines the area between the travel lanes. The Pave surface defines the finished pavement on both travel lanes in the divided highway. This surface is used for calculating cut and fill quantities. This surface represents the grading elevations before pavement materials are applied. The Datum surface tracks the finish grade on unpaved portions, and also the subbase on paved portions, going from the left daylight point to the right daylight point. This surface is used for finish grade modeling. The Top surface tracks the finish grade of the roadway from the left daylight point to the right daylight point on both paved and unpaved portions. In this exercise, you will create Top, Datum, Pave, and Median surfaces from the corridor.
