BasicBenchTargetOneElevation

The BasicBenchTargetOneElevation is a simple bench subassembly that inserts links to create cut or fill catch slopes with one bench.

You can define a swale width and depth at the benches as well as target a single surface at the bench point.

Attachment

The attachment point is at the inside edge of the initial cut or fill slope. This component can be attached to either the left or right side.

Input Parameters

Note: All dimensions are in meters 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
Max Daylight Height	The maximum allowable height for the cut and fill daylight link without benching.	Numeric	15.0 ft 4.5 m
Bench Height	The maximum allowable height for a bench before a new bench.	Numeric	10.0 ft 3.0 m
Bench Slope	The slope between benches.	Numeric, positive	1 (: 1)
Bench Grade In	The +/- % slope of the bench. Positive slopes are upward in the direction of increasing offset.	Numeric	4 (%)
Bench Width In	The width of the bench to the bench flowline	Numeric, positive	4 ft 1.2 m
Bench Grade Out	The +/- % slope of the bench. Positive slopes are upward in the direction of increasing offset.	Numeric	4 (%)
Bench Width Out	The width of the bench from the bench flowline.	Numeric	4 ft 1.2 m
Daylight Slope	The daylight slope.	Numeric, positive	2 (: 1)

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
Daylight Surface	Name of the daylighting surface. The following object types can be used as targets for specifying the surface: surfaces.	Required
Elevation Target	May be used to override the bench elevation and tie to a profile. The following object types can be used as targets for specifying this: profiles, 3D polylines, feature lines, or survey figures.	Optional

Runtime Logical Assignments

None.

Output Parameters

None.

Behavior

The initial hinge point is set at the attachment point. The hinge point elevation is checked against the target surface to determine if the section is in the cut or fill condition. The first link is then built to the target elevation or if not, set to the bench height. The bench links are added. The hinge point is reset to the outside edge of the bench and a daylight link is then found.

Layout Mode Operation

In layout mode, this subassembly draws a cut slope with a bench.

Point, Link, and Shape Codes

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.

Point, Link, or Shape	Code	Description
P1 - P5	Top
P5	Daylight	Daylight point, and daylight point for either the cut or fill condition. This only applies to the actual daylight point.
L1 - L4	Top
