Use this tab to specify layers for various objects in Autodesk Civil 3D. For example, you can specify that you want all alignments on layer C-ROAD, all parcels on C-PROP, and so on. You can also specify prefixes and suffixes for the layer names.
If desired, label layers can be controlled through their label style. However, label object groups and single labels are individual AutoCAD entities, and they always reside on a given AutoCAD layer, as with all other objects. Use this tab to specify the <Object name>-Labeling layers which specifies the default layer the labels will be on when initially created.
Note: These settings also impact the following specific label types:
- Note (use the General Note Label setting)
- Line & Curve (use the General Segment Label setting)
- Alignment Station Offset (use the Alignment-Labeling setting)
- Profile View Station Elevation (use the Profile View-Labeling setting)
- Surface Spot Elevation (use the TIN Surface-Labeling setting)
- Section View Offset Elevation (use the Section View-Labeling setting)
Note: For pipes and structures, when indicating the "object name" as the modifier, use the parent network name, not the name of the pipe or structure. For the Sample Line Labeling setting, the modifier will be the Sample Line Group name, not the name of the individual sample lines.
-
Object
-
Lists all object types in Autodesk Civil 3D.
-
Layer
-
Displays the layer on which the object is drawn. Click to open the Layer Selection dialog box.
-
Modifier
-
Specifies whether the layer name includes a text-string modifier, and if so, the location of the modifier:
- None: No modifier.
- Prefix: Modifier is added at the beginning of the layer name.
- Suffix: Modifier is added at the end of the layer name.
-
Value
-
Specifies the text string to use as the modifier. You can enter an asterisk (*) to include the object name as the modifier in the layer name and to put each named object on its own layer. For example, if C-ROAD is the name specified for alignment layers and you add -* as a suffix, an alignment named overpass is created on layer C-ROAD-OVERPASS.
-
Locked
-
Specifies whether layer settings are locked for the drawing to prevent overrides for individual objects.
-
Immediate And Independent Layer On/Off Control Of Display Components
-
Specifies whether object display is controlled by layer visibility.
- Selected: If an object layer is turned off, the visibility of object subcomponents is not affected if the subcomponents are on a different layer. For example, in a situation where an alignment is on layer C-ROAD and the tangents are on layers C-ROAD_LINE and C-ROAD_CURVE, if you turn off the object layer C-ROAD the lines and curves will still display. However the labels will not display because the label object recognizes that the object layer is turned off.
- Cleared: If an object layer is turned off, the object subcomponents are also turned off (or not drawn) even in situations where the subcomponents are on a different layer.
