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
`InsideWidth`	number (metres unless the description says otherwise)	3.6	Inside lane width (m)
`InsideSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Inside cross slope
`OutsideWidth`	number (metres unless the description says otherwise)	3.6	Outside lane width (m)
`OutsideSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.025	Outside cross slope
`Pave1Depth`	number (metres unless the description says otherwise)	0.025	Pave1 depth (m)
`Pave2Depth`	number (metres unless the description says otherwise)	0.025	Pave2 depth (m)
`BaseDepth`	number (metres unless the description says otherwise)	0.15	Base depth (m)
`SubBaseDepth`	number (metres unless the description says otherwise)	0.3	Sub-base 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
`C0`	Crown	placed at the attachment point (an absolute offset/elevation)	—	`0 / 0`
`B0`	—	offset + elevation delta from the reference point	C0	`SideInsideWidth / InsideWidthInsideSlope`
`E0`	ETW,Lane	offset + elevation delta from the reference point	B0	`SideOutsideWidth / OutsideWidthOutsideSlope`
`C1`	Crown_Pave1	offset + elevation delta from the reference point	C0	`0 / -(Pave1Depth)`
`B1`	—	offset + elevation delta from the reference point	B0	`0 / -(Pave1Depth)`
`E1`	ETW_Pave1	offset + elevation delta from the reference point	E0	`0 / -(Pave1Depth)`
`C2`	Crown_Pave2	offset + elevation delta from the reference point	C0	`0 / -(Pave1Depth+Pave2Depth)`
`B2`	—	offset + elevation delta from the reference point	B0	`0 / -(Pave1Depth+Pave2Depth)`
`E2`	ETW_Pave2	offset + elevation delta from the reference point	E0	`0 / -(Pave1Depth+Pave2Depth)`
`C3`	Crown_Base	offset + elevation delta from the reference point	C0	`0 / -(Pave1Depth+Pave2Depth+BaseDepth)`
`B3`	—	offset + elevation delta from the reference point	B0	`0 / -(Pave1Depth+Pave2Depth+BaseDepth)`
`E3`	ETW_Base	offset + elevation delta from the reference point	E0	`0 / -(Pave1Depth+Pave2Depth+BaseDepth)`
`C4`	Crown_SubBase	offset + elevation delta from the reference point	C0	`0 / -(Pave1Depth+Pave2Depth+BaseDepth+SubBaseDepth)`
`B4`	—	offset + elevation delta from the reference point	B0	`0 / -(Pave1Depth+Pave2Depth+BaseDepth+SubBaseDepth)`
`E4`	ETW_SubBase	offset + elevation delta from the reference point	E0	`0 / -(Pave1Depth+Pave2Depth+BaseDepth+SubBaseDepth)`
