Adding Boundaries to a Corridor Surface

Product Documentation

View Original

Use the Boundaries tab of the Corridor Properties dialog box, or the Create Boundary From Corridor command on the Create Design panel of the Home tab, to create corridor boundaries.

In the Boundaries tab, you can create the boundaries using the following options:

  • Add Automatically, when there is a single baseline, based on point codes to which feature lines are assigned
  • Corridor Extents As Outer Boundary, when there are multiple baselines, based on feature lines or surface link codes
  • Add Interactively, by selecting feature lines in the drawing
  • Add From Polygon, using a closed polygon that forms the boundary

When selecting the feature lines from which to create the boundary, first select the bottom end of one feature line, followed by the top end of its pair.

For example, select the bottom outside edge of a lane followed by the top outside edge of a lane to create a boundary that encompasses both lanes:

If you are creating the corridor boundary using a polygon, you can create the required polygon by exporting corridor feature lines as polylines, and then join them to create the required polygon.

For more information about converting feature lines to polylines, see Exporting Corridor Data.

Note

The Add Automatically option to add boundaries Automatically is not available if more than one baseline is used in the corridor. In that case, select Corridor Extents As Outer Boundary, to automatically add a boundary for each corridor surface.

To automatically create outer boundaries

  1. In the drawing, click the corridor, then right-click and click Corridor Properties.

    You can also access this functionality from the ribbon by clicking Corridor tabModify Corridor panelCorridor Surfaces..

  2. Click the Boundaries tab.
  3. Right-click the corridor surface to which you want to add a mask.
    • To automatically add a boundary to a corridor with a single baseline, click Add Automatically <code name>.
      Note

      Only point codes that form a pair of feature lines in the corridor are listed, for example daylight and ETW.

    • To automatically add a boundary to a corridor with multiple baselines, click Corridor Extents As Outer Boundary.

    The boundary is added to the corridor surface where you can modify its name, style usage and type. For information, see Editing a Corridor Mask.

To interactively add a boundary to a corridor surface

  1. In the drawing, click the corridor, then right-click and click Corridor Properties.

    You can also access this functionality from the ribbon by clicking Corridor tabModify Corridor panelCorridor Surfaces.

  2. Click the Boundaries tab.
  3. Right-click the corridor surface to which you want to add a boundary. Click Add Interactively.
    Note

    A corridor surface must exist before you can add a corridor boundary. For information about creating a corridor surface, see Creating and Editing Corridor Surfaces.

  4. In the drawing, click a corridor feature line that will form one side of the boundary. If you make an ambiguous selection, the Select A Feature Line dialog box is displayed. Select a feature line from the list.
  5. In the drawing, click the corridor feature line that will form the other side of the boundary. If you make an ambiguous selection, the Select A Feature Line dialog box is displayed. Select a feature line from the list.
  6. When you finish selecting the feature lines, press Enter.
  7. In the Boundaries tab grid, expand the corridor surface to display the boundary.
  8. Click Use Type. Select the type of boundary, either: Render Only, Hide Boundary, or Outside Boundary.
  9. Click Apply.

To create outer boundaries using a closed polygon

  1. In the drawing, click the corridor, then right-click and click Corridor Properties.

    You can also access this functionality from the ribbon by clicking Corridor tabModify Corridor panelCorridor Surfaces..

  2. Click the Boundaries tab.
  3. Right-click the corridor surface to which you want to add a mask. Click Add From Polygon.
  4. In the drawing window, click the closed polygon you want to use to define the boundaries of the corridor surface.

  5. The boundary is added to the corridor surface where you can modify its name, render style, and type. For more information, see Editing a Corridor Boundary.

Note

If you create an invalid boundary, you will be prompted to continue (and correct the error), to save the invalid boundary (which can be corrected later), or to cancel the boundary creation.

To create a polyline boundary from a corridor

  1. Click Home tabCreate Design panelCreate Boundary From Corridor.
  2. Click a corridor in the drawing, or press Enter to select a corridor in the Select A Corridor dialog box.

    A closed polyline is created as the outer boundary of the corridor. This closed polyline can then be used to create a surface boundary, using the Add From Polygon command.
