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
`InsideLaneWidth`	number (metres unless the description says otherwise)	3.6	Median edge to crown fallback (m)
`DefaultInsideSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.02	Inner lane slope (rising to the crown)
`OutsideLaneWidth`	number (metres unless the description says otherwise)	3.6	Crown to outer edge fallback (m)
`DefaultOutsideSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Outer lane slope
`InsideAdjustment`	number (metres unless the description says otherwise)	0	Inner edge trim (m)
`OutsideAdjustment`	number (metres unless the description says otherwise)	0	Outer edge trim (m)
`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	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
`P0`	—	placed at the attachment point (an absolute offset/elevation)	—	`0 / 0`
`P1`	ETW	offset + elevation delta from the reference point	P0	`SideInsideAdjustment / InsideAdjustmentDefaultInsideSlope`
`P2`	Crown	offset + elevation delta from the reference point	P0	`SideInsideLaneWidth / InsideLaneWidthDefaultInsideSlope`
`P3`	ETW	offset + elevation delta from the reference point	P2	`Side(OutsideLaneWidth-OutsideAdjustment) / (OutsideLaneWidth-OutsideAdjustment)DefaultOutsideSlope`
`P4`	ETW_Pave1	offset + elevation delta from the reference point	P1	`0 / -Pave1Depth`
`P5`	Crown_Pave1	offset + elevation delta from the reference point	P2	`0 / -Pave1Depth`
`P6`	ETW_Pave1	offset + elevation delta from the reference point	P3	`0 / -Pave1Depth`
`P7`	ETW_Pave2	offset + elevation delta from the reference point	P4	`0 / -Pave2Depth`
`P8`	Crown_Pave2	offset + elevation delta from the reference point	P5	`0 / -Pave2Depth`
`P9`	ETW_Pave2	offset + elevation delta from the reference point	P6	`0 / -Pave2Depth`
`P10`	ETW_Base	offset + elevation delta from the reference point	P7	`0 / -BaseDepth`
`P11`	Crown_Base	offset + elevation delta from the reference point	P8	`0 / -BaseDepth`
`P12`	ETW_Base	offset + elevation delta from the reference point	P9	`0 / -BaseDepth`
`P13`	ETW_SubBase	offset + elevation delta from the reference point	P10	`0 / -SubbaseDepth`
`P14`	Crown_SubBase	offset + elevation delta from the reference point	P11	`0 / -SubbaseDepth`
`P15`	ETW_SubBase	offset + elevation delta from the reference point	P12	`0 / -SubbaseDepth`
