C3D TrenchPipe3 — pipe trench with a rock excavation tier

At a glance


Kind	Subassembly (composed into an assembly)
Domain	Miscellaneous
Civil 3D equivalent	`TrenchPipe3`
Geometry	9 points, 8 links, 2 shapes
Targets	1 (surface / offset / elevation targets this subassembly can be linked to)

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
`Sideslope`	cross slope as a ratio (−0.02 = 2 % fall)	0.333333	Trench wall (rise/run)
`Width`	number (metres unless the description says otherwise)	1.8	Trench floor width (m)
`BeddingDepth`	number (metres unless the description says otherwise)	0.15	Bedding under the pipe invert (m)
`PipeNetworkOffset1`	number (metres unless the description says otherwise)	0	Shift from the pipe centreline (m)
`RockDepth`	number (metres unless the description says otherwise)	0.3	Rock taken out below the bedding (m)
`RockWidth`	number (metres unless the description says otherwise)	2.4	Rock excavation width (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`
`T1`	Trench	offset + elevation delta from the reference point	P0	`PX-Side*Width/2 / FY`
`T2`	Trench	offset + elevation delta from the reference point	P0	`PX+Side*Width/2 / FY`
`T3`	Trench	offset + elevation delta from the reference point	T2	`Side*abs(FY)/Sideslope / 0-FY`
`T4`	Trench	offset + elevation delta from the reference point	T1	`0-Side*abs(FY)/Sideslope / 0-FY`
`R1`	—	offset + elevation delta from the reference point	P0	`PX-Side*RockWidth/2 / FY-RockDepth`
`R2`	—	offset + elevation delta from the reference point	P0	`PX+Side*RockWidth/2 / FY-RockDepth`
`R3`	—	offset + elevation delta from the reference point	P0	`PX+Side*RockWidth/2 / FY`
`R4`	—	offset + elevation delta from the reference point	P0	`PX-Side*RockWidth/2 / FY`
