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
`ShoulderWidth`	number (metres unless the description says otherwise)	2.4	Shoulder width (m)
`ShoulderSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Shoulder cross slope
`HoldDaylightSlope`	number (metres unless the description says otherwise)	1	1 = hold slope (derive width), 0 = hold width
`DaylightSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.25	Daylight slope when held
`DaylightWidth`	number (metres unless the description says otherwise)	1.62	Daylight width when held (m)
`SubbaseSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Subbase bottom 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)	0.1	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
`P1`	—	placed at the attachment point (an absolute offset/elevation)	—	`0 / 0`
`P2`	EPS	offset + elevation delta from the reference point	P1	`SideShoulderWidth / ShoulderWidthShoulderSlope`
`P3`	—	offset + elevation delta from the reference point	P1	`0 / -Pave1Depth`
`P5`	—	offset + elevation delta from the reference point	P3	`0 / -Pave2Depth`
`P7`	—	offset + elevation delta from the reference point	P5	`0 / -BaseDepth`
`P9`	—	offset + elevation delta from the reference point	P7	`0 / -SubbaseDepth`
`P4`	EPS_Pave1	offset + elevation delta from the reference point	P2	`-SidePave1Depth/(DS-ShoulderSlope) / -Pave1DepthDS/(DS-ShoulderSlope)`
`P6`	EPS_Pave2	offset + elevation delta from the reference point	P4	`-SidePave2Depth/(DS-ShoulderSlope) / -Pave2DepthDS/(DS-ShoulderSlope)`
`P8`	EPS_Base	offset + elevation delta from the reference point	P6	`-SideBaseDepth/(DS-ShoulderSlope) / -BaseDepthDS/(DS-ShoulderSlope)`
`P10`	Daylight_Sub	offset + elevation delta from the reference point	P9	`Side(ShoulderWidth+DW) / (ShoulderWidth+DW)SubbaseSlope`
