Benching

The Benching subassembly inserts links to create a benching. The benching may be created from the inside toe or inside top of the benching. The benching then daylights to a surface.

Attachment

The attachment point is at the inside toe or inside top of the benching. 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
Attach Point	Attach point where the benching will be built from.	Inside Toe / Inside Top	Inside Toe
Benching Height	Height of benching measured from the attachment point.	Numeric	4 ft 1.2 m
Outside Side Slope	Benching slope on the outside of the benching.	Numeric	-2 ( : 1)
Inside Side Slope	Benching slope on the inside of the benching.	Numeric	3 ( : 1)
Top Gradient	Gradient of the top of the benching.	Numeric	2 (%)
Top Width	Top width of the benching.	Numeric, positive	5 ft 1.5 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
Benching Surface	Name of the daylighting surface. The following object types can be used as targets for specifying the surface: surfaces.	Optional

Runtime Logical Assignments

None.

Output Parameters

None.

Behavior

The initial inside link of the benching is created using the entered height and inside side slope. The top of the benching is created using the entered Top Width and Top Gradient. A daylight link is found using the Outside Side Slope.

Layout Mode Operation

In layout mode, this subassembly draws the benching in fill with a link of 5 ft (1.5 m).
