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)	-0.06	Shoulder cross slope (SE fallback)
`SubbaseSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.06	Subbase bottom 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)	2.37	Daylight width when held (m)
`Pave1Extension`	number (metres unless the description says otherwise)	0	Pave1 reach past the hinge (m)
`Pave2Extension`	number (metres unless the description says otherwise)	0	Pave2 reach past the hinge (m)
`BaseExtension`	number (metres unless the description says otherwise)	0	Base reach past the hinge (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)	0.1	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`
`P10`	—	offset + elevation delta from the reference point	P1	`0 / 0-(Pave1Depth)`
`P9`	—	offset + elevation delta from the reference point	P1	`0 / 0-(Pave1Depth+Pave2Depth)`
`P8`	—	offset + elevation delta from the reference point	P1	`0 / 0-(Pave1Depth+Pave2Depth+BaseDepth)`
`P12`	—	offset + elevation delta from the reference point	P1	`0 / 0-(Pave1Depth+Pave2Depth+BaseDepth+SubbaseDepth)`
`P4`	EPS_Pave1	offset + elevation delta from the reference point	P1	`Side(min(ShoulderWidth+Pave1Extension,(ShoulderWidth+(Pave1Depth)/(ShoulderSlope-DS)))) / 0-(Pave1Depth)+(min(ShoulderWidth+Pave1Extension,(ShoulderWidth+(Pave1Depth)/(ShoulderSlope-DS))))ShoulderSlope`
`P3`	—	offset + elevation delta from the reference point	P1	`Side(min(ShoulderWidth+Pave1Extension,(ShoulderWidth+(Pave1Depth)/(ShoulderSlope-DS)))) / ShoulderWidthShoulderSlope+((min(ShoulderWidth+Pave1Extension,(ShoulderWidth+(Pave1Depth)/(ShoulderSlope-DS))))-ShoulderWidth)*DS`
`P5`	—	offset + elevation delta from the reference point	P1	`Side(min(ShoulderWidth+Pave2Extension,(ShoulderWidth+(Pave1Depth)/(ShoulderSlope-DS)))) / 0-(Pave1Depth)+(min(ShoulderWidth+Pave2Extension,(ShoulderWidth+(Pave1Depth)/(ShoulderSlope-DS))))ShoulderSlope`
`P13`	EPS_Pave2	offset + elevation delta from the reference point	P1	`Side(min(ShoulderWidth+Pave2Extension,(ShoulderWidth+(Pave1Depth+Pave2Depth)/(ShoulderSlope-DS)))) / 0-(Pave1Depth+Pave2Depth)+(min(ShoulderWidth+Pave2Extension,(ShoulderWidth+(Pave1Depth+Pave2Depth)/(ShoulderSlope-DS))))ShoulderSlope`
