Use this dialog box to set and edit the mapping of targets in subassemblies to the names of actual objects in the drawing.
The corridor Target Mapping dialog box is modeless so you can keep it open while you do other work. You can pin the dialog box open so it stays expanded, or you can unpin the dialog box so that only the title is displayed when you move your cursor off the dialog box.

Displays the name of the selected corridor for which you are setting targets.
Displays the end station for the baseline in which the selected subassembly exists.




Use this tab to specify offset and elevation targets.

Displays the name of the subassemblies that require the targets. Expand the subassembly collections to display the targets to specify for those subassemblies. You can click
to expand the list of targets for the subassemblies.
Displays the region of the corridor in which the subassembly is in use.
Displays the assembly in use for the corridor.
Displays the side of the assembly that the subassembly is attached to.
Displays the name of the assembly group.
Specifies the offset or width targets. Click in a cell in this column to display the Set Offset Targets controls at the bottom of the dialog box.
Specifies the elevation or slope targets. Click in a cell in this column to display the Set Elevation Targets controls at the bottom of the dialog box.
Use this section of the dialog box to specify the offset/width and elevation/slope targets. The title of this section changes depending on where you have clicked in the dialog box. If you click in a cell in the Offset column, the title is Set Offset Targets. If you click in a cell in the Elevation column, the title is Set Elevation Targets.
to select an object in the drawing. Click
to select the object by layer.
to refine the selection of objects on that layer if needed. Click
to select an object in the drawing. To update the corridor after objects on the layer have changed or have been added, one of the following workflows must be used:
next to the layer name in the Target Mapping dialog box to display the Select Entities dialog box and then selecting the object in the list.
When specifying an offset target, you can use these settings to specify which offset to target if there are two or more targets in the Select Entities To Target list.
Use this tab to specify surface targets.
Displays the name of the subassembly that requires the target.
Displays the baseline of the corridor.
Displays the region of the corridor.
Displays the assembly in use for the corridor.
Displays the side of the assembly that the subassembly is attached to.
Displays the name of the assembly group.

Displays the name of the corridor.
Displays the name of the assembly. If you are viewing the target for an entire corridor, for which there is more than one baseline, ‘**Varies**’ is displayed.
Displays the start station for the assembly’s region or the start station on the corridor baseline. If you are viewing the target for the entire corridor for which there is more than one baseline, ‘**Varies**’ is displayed.
Displays the end station for the assembly’s region or the end station on the corridor baseline. If you are viewing the target for the entire corridor for which there is more than one baseline, ‘**Varies**’ is displayed.
The properties table contains the following columns:
Lists targets that are required by the corridor’s subassemblies, categorized into three groups: Surfaces, Width Or Offset Targets, and Slope Or Elevation Targets.
Opens either the Pick A Surface, Set Width Or Offset Target, Set Slope Or Elevation Target or Select Pipe Network dialog box, where you can select the Autodesk Civil 3D object name to map to the subassembly target.
Displays the name of the subassembly that requires the target.
Displays the name of the assembly group.
