Simple Noise Barrier

C3D SimpleNoiseBarrier — earth-berm noise wall + optional topsoil band

At a glance


Kind	Subassembly (composed into an assembly)
Domain	Miscellaneous
Civil 3D equivalent	`SimpleNoiseBarrier`
Geometry	9 points, 6 links, 1 shapes
Conditional geometry	4 of the points are created inside a branch — which ones appear depends on the parameters and the target surface

Parameters

Defaults are the metric values the palette inserts. Every parameter can be driven by an expression or a target.

Parameter	Type	Default	Meaning
`Side`	+1 right of the baseline, −1 left	Right (+1)	+1 Right / -1 Left
`TopWidth`	number (metres unless the description says otherwise)	0.9	Berm top width (m)
`Foreslope`	cross slope as a ratio (−0.02 = 2 % fall)	1.5	Front slope (rise/run)
`Backslope`	cross slope as a ratio (−0.02 = 2 % fall)	1.5	Back slope (rise/run)
`Height`	number (metres unless the description says otherwise)	2.7	Berm height (m)
`TopsoilThickness`	number (metres unless the description says otherwise)	0	Lining thickness; 0 = none (m)

Points

Point codes are what feature lines, styles and quantity take-off match on — they are the contract this subassembly publishes.

Point	Code	Placed	From	Expression
`P0`	—	placed at the attachment point (an absolute offset/elevation)	—	`0 / 0`
`P3`	Bench_In	offset + elevation delta from the reference point	P0	`Side*Height/abs(Foreslope) / Height`
`P4`	Bench_Out	offset + elevation delta from the reference point	P3	`Side*TopWidth / 0`
`P1`	RW_Top	offset + elevation delta from the reference point	P3	`Side*TopWidth/2 / 0`
`P2`	RW_Outside	offset + elevation delta from the reference point	P4	`Side*Height/abs(Backslope) / -Height`
`P5` conditional	—	offset + elevation delta from the reference point	P0	`Side*TopsoilThickness/abs(Foreslope) / 0`
`P6` conditional	—	offset + elevation delta from the reference point	P3	`0 / -TopsoilThickness`
`P7` conditional	—	offset + elevation delta from the reference point	P4	`0 / -TopsoilThickness`
`P8` conditional	—	offset + elevation delta from the reference point	P2	`Side*TopsoilThickness/abs(Backslope) / 0`
