The Dam subassembly inserts links to create a representation of a dam. A progress profile is present to adjust the dam geometry to reflect the progress.
Attachment
The attachment point is at the center of the dam.

Target Parameters
This section lists the parameters in this subassembly that can be mapped to one or more target objects. For more information, see To Specify Corridor Targets.
|
Parameter |
Description |
Status |
|---|---|---|
| Dam Daylight Surface | Name of the daylighting surface. The following object types can be used as targets for specifying the surface: surfaces. | Required |
| Progress Profile | May be used to show progress of the dam based on the elevation of the elevation target. The following object types can be used as targets for specifying the elevation: profiles, 3D polylines, feature lines, or survey figures. | Optional |
Runtime Logical Assignments
None.
Output Parameters
None.
Behavior
The initial point is set at the attachment point. The outside daylight links are built. The interior structure of the dam is built based on the input parameters. The bottom surface of the dam is based on the Dam Daylight Surface.
If the progress profile is present then shapes are calculated based on the progress elevation. The elevation is applied as a level surface.
Layout Mode Operation
In layout mode, this subassembly displays the dam based on the input parameters given with a height of 20 ft (6 m).
Point, Link, and Shape Codes
