■ Render Only - Used to represent different parts of corridor surface with different materials (when rendering), for example, asphalt and grass. NOTE A Corridor Extents As Outer Boundary command is available for corridors that have multiple baselines, such as a corridor at an intersection. For more information, see the AutoCAD Civil 3D Help topic Adding and Editing Corridor Boundaries. This exercise continues from Exercise 1: Creating Corridor Surfaces (page 483). Create outside boundaries automatically 1 Open Corridor-5b.dwg, which is available in the tutorial drawings folder (page 819). 2 In the drawing, select the corridor. TIP If you have difficulty selecting the corridor in the drawing, go to Toolspace on the Prospector tab. Expand the Corridors collection. Right-click the corridor name and click Select. 3 Click Corridor tab ➤ Modify Corridor panel ➤ Corridor Surfaces . 4 In the Corridor Surfaces dialog box, click the Boundaries tab. Four corridor surfaces are displayed in the boundary table. 5 Select the Corridor - (1) Top surface. Right-click. Click Add Automatically ➤ Daylight. This creates a boundary from the daylight lines that are generated from the daylight point codes in the subassembly. NOTE A Corridor Extents As Outer Boundary command is available for corridors that have multiple baselines, such as a corridor at an intersection. 6 Select the Corridor - (1) Datum surface. Right-click. Click Add Automatically ➤ Daylight. 7 For both boundaries, make sure the Use Type is set to Outside Boundary. The daylight line in the corridor model is created at the points where the design surface matches the existing ground on each side. By selecting Outside Boundary, the surface will be clipped outside the boundary formed by the left and right daylight lines. Exercise 2: Creating Corridor Surface Boundaries | 487
