CrossChannel

Attachment

The attachment point is at flowline of the cross channel. This component can be attached to either the left or right side.

Input Parameters

Note: Note: All dimensions are in metres or feet unless otherwise noted. All slopes are in run-over-rise form (for example, 4 : 1) unless indicated as a percent slope with a “%” sign.

Parameter	Description	Type	Default
Side	Specifies which side to place the subassembly.	Left / Right	Right
Channel Composition	Determines if the left, right, or both are built	Both / Left / Right	Both
Base Thickness	Thickness of base under channel	Numeric, positive	0.5 ft 0.15 m
Channel Depth At Flowline	Depth of channel at the flowline	Numeric, positive	0.5 ft 0.15 m
Channel Gradient	Channel gradient	Numeric	8 (%)
Channel Width Left	Channel width left	Numeric, positive	3 ft 0.9 m
Channel Width Right	Channel width right	Numeric	3 ft 0.9 m

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
Edge Level Right	May be used to override the right edge level of the cross channel. The following object types can be used as targets for specifying the level: profiles, 3D polylines, feature lines, or survey figures.	Optional
Edge Level Left	May be used to override the left. The following object types can be used as targets for specifying the level: profiles, 3D polylines, feature lines or survey figures.	Optional
Edge Offset Left	May be used to override the left edge level of the cross channel. The following object types can be used as targets for specifying this offset: alignments, polylines, features lines or survey figures.	Optional
Edge Offset Right	May be used to override the right width of the cross channel. The following object types can be used as targets for specifying this offset: alignments, polylines, features lines or survey figures.	Optional

Runtime Logical Assignments

None.

Output Parameters

None.

Behavior

The channel links are inserted based on the input parameters. The targets may override the outside edge of the cross channel on both the right and left sides. If the base thickness is greater than 0, then the base is built under the cross channel.

Layout Mode Operation

In layout mode, this subassembly displays the cross channel components based on the input parameters given.
