BasicCurbAndGutter

This subassembly creates a a simple curb and gutter structure at the inside or outside edges of roadway.

This subassembly is one of a group of Getting Started subassemblies used for simple roadway modeling, and for tutorial and training purposes.

Attachment

The attachment point is at the flange point of the gutter or back of the curb.

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
Insertion Point	Specifies insertion point of the curb and gutter as either Gutter Edge or Back of Curb	Boolean	Gutter Edge
Gutter Width	Width from the flange of the gutter to the flowline	Numeric, positive	0.45 m 1.5 ft
Gutter %Slope	% slope of the gutter	Numeric	-6%
Curb Height	Height from the flowline to the top of curb	Numeric, positive	0.225 m 0.75 ft
Curb Width	Width of the top of curb	Numeric, positive	0.15 m 0.5 ft

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.

Target Parameters: None.

Output Parameters

None.

Behavior

The subassembly builds the shape for a simple curb and gutter with the attachment point either at (a) the inside edge of the gutter (or lip), or (b) the back of the curb. The face of the curb is given a small, constant width to make it non-vertical.

Layout Mode Operation

In layout mode, this subassembly draws the curb and gutter shape as specified by the input parameter values.
