Setting Targets

Product Documentation

View Original

On a corridor, you can set and edit the values of subassembly target objects, such as surfaces, alignments, and profiles.

Targets are required when the geometry of one or more of an assembly’s subassemblies requires corresponding surface, offset, or elevation targets for defining that geometry.

A few subassemblies even use pipe networks as target objects. When a corridor contains subassemblies that use targets, the object names of the intended target objects must be mapped from the subassembly definition to the corresponding drawing objects. This task is referred to as setting targets or mapping targets.

Note

If targets required for the corridor are not set, messages are displayed in the Event Viewer, indicating that target objects are not found. To display the Event Viewer, click View tab Palettes panel Event Viewer . For more information about the event viewer, see The Civil 3D Event Viewer Vista.

For example, a subassembly ‘SideSlope’ parameter is used to define roadside grading, starting from the edge of shoulder, and sloping at a specified grade, until it intercepts with an existing ground surface. In the subassembly, references to the target surface are made by calling a surface object named ‘TargetDTM.’ However, when you create the corridor, and apply the subassembly to a corridor definition, there may not be a surface named ‘TargetDTM’, and there may be multiple ground surfaces. Therefore, after the assembly is applied to the corridor, you need to map the target name (TargetDTM) to an actual surface object name.

Typically, subassembly parameters that can use a target object to define a width or an offset can use the following types of objects to define that width or offset: alignments, polylines, feature lines, or survey figures.

Similarly, subassembly parameters that can use a target object to define an elevation can use the following types of objects to define that elevation: profiles, 3D polylines, feature lines, or survey figures.

Subassemblies that can use a target object to define a surface can only use a surface object to define that surface.

As previously mentioned, a few subassemblies allow you to use pipe network objects as targets, such as the TrenchPipe subassemblies.

The following table summarizes these capabilities:

Target Type Object types that can be used as targets
widths or offsets alignments, polylines, feature lines, or survey figures
elevations profiles, 3D polylines, feature lines, or survey figures
surfaces surfaces
pipe networks pipe networks

The Help topic for each subassembly lists the parameters in the subassembly that can be associated with a target object.

Best Practice

It is generally considered a best practice to set region targets after creating the regions. For example, while creating regions, leave the targets set to “None”, and proceed with creating the regions. After the regions are created, set the targets on the regions. This reduces the processing load because processing the assembly insertion points (during region creation), and processing the setting of the assembly targets, are two separate operations instead of one.

Tutorial: Creating a Corridor with a Transition Lane

To set targets using the ribbon

  1. In the drawing, select the corridor.
  2. Click Corridor tabModify Region panelEdit Targets.
  3. In the drawing, select a region to edit.
  4. In the Target Mapping dialog box, set the surface, offset, and elevation targets in the corresponding Object Name fields.
  5. Click OK to close the Target Mapping dialog box.
  6. Click Apply.
  1. Select a corridor in the drawing.
  2. Click Corridor tabModify Corridor Sections panelSection Editor.
  3. On the Section Editor RibbonStation Selection panel, select a station that is in the region you want to change.

    In the Select a Station list, indicates that a station is associated with a region.

  4. In section editor, select the assembly. Hover the cursor over the grip for the subassembly you want to edit targets. Click the type of target that you want to edit.
    NoteIf multiple subassemblies share a grip, then Edit Shared Targets is displayed. If you select Edit Shared Targets, the Target Mapping Dialog Box is displayed.
  5. In the drawing, select the object to target. Press Enter.
  6. Specify the target object from the dialog box that is displayed.

    For more information, see Set Width or Offset Target Dialog Box, Set Slope or Elevation Target Dialog Box, Pick a Surface Dialog Box, or Select Object(s) Dialog Box.

To set targets using the Corridor Properties dialog box

  1. In the drawing, click the corridor, then right-click and click Corridor Properties.
  2. In the Corridor Properties dialog box, click the Parameters tab.
  3. Do one of the following:
    • To view or map all targets required by the corridor, click Set All Targets.
    • To view or map the targets for a specific baseline or assembly, click the Target field for that baseline or assembly.
  4. In the Target Mapping dialog box, set the surface, offset, and elevation targets in the corresponding Object Name fields.
  5. Click OK to close the Target Mapping dialog box.
  6. Click Apply.

To select a surface to target

  1. In the Target Mapping dialog box, do one of the following:
    • To select surfaces individually, click the Object Name field next to the corresponding surface in the Target column.
    • To select all surfaces at once, click <Click Here To Set All> in the Object Name field. This is useful for mapping TargetDTM's that are referenced by multiple subassemblies used in the corridor through multiple assembly regions. For example, all side slope subassemblies typically need to be mapped to the same existing ground surface.
  2. In the Pick a Surface dialog box, select the surface from the list or click and select the surface in the drawing.
  3. Click OK to close the Pick a Surface dialog box.

To select a width or offset to target

  1. In the Target Mapping dialog box, click the Object Name field next to the corresponding width or offset target name in the Target column.
  2. To target an alignment:
    • In the Select Object Type To Target list of the Set Width Or Offset Target dialog box, select Alignment.
    • Select an alignment from the Alignment list, or click and select an alignment in the drawing, to add to the list.
    • Click Add >> to add an alignment to the Selected Entities to Target list.
  3. To target a feature line, survey figure or polyline:
    • In the Select Object Type To Target of the Set Width Or Offset Target dialog box select Feature Lines, Survey Figures and Polylines.
    • Click Select By Layer to import all named targets on any layer selected in the Select By Layer, dialog box or click Select From Drawing to select entities in the drawing.
    • Click to remove any excess entities from the Selected Entities To Target list.
    • If there are two or more targets in the Selected Entities To Target list, select Target To Nearest Offset or Target To Farthest Offset for Selection Choice If Multiple Targets Are Found.
  4. Click OK to close the Set Width Or Offset Target dialog box.
Note

If you select more than one target object, **Varies** is displayed in the Object Name field.

To select a slope or elevation to target

  1. In the Target Mapping dialog box, click the Object Name field next to the corresponding slope or elevation target name in the Target column.
  2. To target a profile:
    • In the Set Slope Or Elevation Target dialog box, in the Select Object Type To Target list, select Profiles.
    • Select from the Select An Alignment list, or click and select an alignment in the drawing.
    • Select from the Select Profiles list, or click and in the drawing select a profile to add to the list.
    • Click Add >> to add a profile to the Selected Entities To Target list.
  3. To target a feature line, survey figure or polyline:
    • In the Select Object Type To Target of the Set Slope Or Elevation Target dialog box select, Feature Lines, Survey Figures and Polylines.
    • Click Select By Layer to import all named targets on any layer selected in the Select By Layer dialog box or click Select From Drawing to select entities in the drawing.
    • Click to remove any excess entities from the Selected Entities to Target list.
    • If there are two or more targets in the Selected Entities To Target list, select Target To Nearest Offset or Target To Farthest Offset for Selection Choice If Multiple Targets Are Found.
  4. Click OK to close the Set Slope or Elevation Target dialog box.
Note

If you select more than one target object, **Varies** is displayed in the Object Name field.
