This subassembly inserts links for a constant-slope raised median between two points.
Use the MarkPoint subassembly first if the connecting point has not already been marked.
The attachment point may be at either edge of the median finished grade. The marked point must be at the opposite edge.
Note: Subbase dimensions are in meters or feet. Curb-and-gutter dimensions must be given in millimeters or inches.
This section lists the parameters in this subassembly that can be mapped to one or more target objects, such as a surface, alignment, or profile object in a drawing. For more information, see in the AutoCAD Civil 3D User’s Guide Help.
| Parameter | Description | Type |

Superelevation Axis of Rotation |
Indicates whether the subassembly supports the axis of rotation calculation. To view a description of the parameter, in the Properties window, hover the cursor over the parameter. For more information, see Profile Grade Line Adjustments During Superelevation. |
Static (Description) |
The median crown point is calculated by intersecting lines extended between the attachment point and the marked point at the given slopes. If no intersection is found, the median is not inserted. If a non-zero Depth is given, the bottom of the median links are inserted parallel to the top, and vertical links are added to close the shape.
Superelevation Axis of Rotation Support
This subassembly works with all axis of rotation pivot methods.
This subassembly produces a raised crown. Even when it is used in a divided crown roadway, the center of the median will be higher than the median edges.
The following table lists the point, link, and shape codes for this subassembly that have codes assigned to them. Point, link, or shape codes for this subassembly that do not have codes assigned are not included in this table.
