At a glance


Kind	Subassembly (composed into an assembly)
Domain	Road
Civil 3D equivalent	`CrownedLane`
Geometry	15 points, 18 links, 4 shapes
Targets	5 (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
`LeftLaneWidth`	number (metres unless the description says otherwise)	3.6	Left lane width (m)
`RightLaneWidth`	number (metres unless the description says otherwise)	3.6	Right lane width (m)
`DefaultLeftSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Left lane cross slope
`DefaultRightSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Right lane cross slope
`BaseLeftSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.03	Left base cross slope
`BaseRightSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.03	Right base cross slope
`Pave1Depth`	number (metres unless the description says otherwise)	0.025	Pave 1 depth (m)
`Pave2Depth`	number (metres unless the description says otherwise)	0.025	Pave 2 depth (m)
`BaseDepth`	number (metres unless the description says otherwise)	0.1	Base depth (m)
`SubBaseDepth`	number (metres unless the description says otherwise)	0.3	Subbase depth (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
`C`	Crown	placed at the attachment point (an absolute offset/elevation)	—	`0 / 0`
`L`	ETW	offset + elevation delta from the reference point	C	`0-LW / LW*LS`
`R`	ETW	offset + elevation delta from the reference point	C	`RW / RW*RS`
`L1`	ETW_Pave1	offset + elevation delta from the reference point	L	`0 / 0-Pave1Depth`
`C1`	Crown_Pave1	offset + elevation delta from the reference point	C	`0 / 0-Pave1Depth`
`R1`	ETW_Pave1	offset + elevation delta from the reference point	R	`0 / 0-Pave1Depth`
`L2`	ETW_Pave2	offset + elevation delta from the reference point	L1	`0 / 0-Pave2Depth`
`C2`	Crown_Pave2	offset + elevation delta from the reference point	C1	`0 / 0-Pave2Depth`
`R2`	ETW_Pave2	offset + elevation delta from the reference point	R1	`0 / 0-Pave2Depth`
`CB`	Crown_Base	offset + elevation delta from the reference point	C2	`BX / 0-BaseDepth`
`LB`	ETW_Base	offset + elevation delta from the reference point	L2	`0 / if(BaseDepth>0,0-BaseDepth+LW*(BaseLeftSlope-LS),0)`
`RB`	ETW_Base	offset + elevation delta from the reference point	R2	`0 / if(BaseDepth>0,0-BaseDepth+RW*(BaseRightSlope-RS),0)`
`LS_`	Lane_Sub	offset + elevation delta from the reference point	LB	`0 / 0-SubBaseDepth`
`CS`	Crown_Sub	offset + elevation delta from the reference point	CB	`0 / 0-SubBaseDepth`
`RS_`	Lane_Sub	offset + elevation delta from the reference point	RB	`0 / 0-SubBaseDepth`
