The KerbOffsetPipe subassembly is used to place a kerb and channel with a pipe behind the kerb and channel. A terrace is also placed behind the kerb.
Attachment
The attachment point is at the flange point of the channel.

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 |
|---|---|---|
|
Terrace Width |
May be used to override the terrace width value and tie the terrace width to an offset alignment. The following object types can be used as targets for specifying the width: alignments, polylines, feature lines, or survey figures. | Optional |
|
Terrace Level |
May be used to override the terrace slope and tie the level of the terrace to the level of a profile. The following object types can be used as targets for specifying the level: profiles, 3D polylines, feature lines, or survey figures. | Optional |
|
Pipe Offset |
May be used to override the pipe offset value and tie the pipe to an offset alignment. The following object types can be used as targets for specifying the width: alignments, polylines, feature lines, or survey figures. | Optional |
Runtime Logical Assignments
None.
Output Parameters
None.
Behavior
The subassembly builds a shape for a simple kerb and channel, with the attachment point at the flange of the channel. A pipe is then placed behind the kerb with bedding material. A terrace is then placed behind the pipe bedding material.
Layout Mode Operation
In layout mode, this subassembly displays the kerb-and-channel, pipe, and terrace components based on the input parameters given.
Point, Link, and Shape Codes
