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
`WideningWidth`	number (metres unless the description says otherwise)	3.6	New pavement added at the curb (m)
`OverlayWidth`	number (metres unless the description says otherwise)	3.6	Existing pavement covered by the overlay (m)
`Slope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Design 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
`P4`	ETW	placed at the attachment point (an absolute offset/elevation)	—	`0 / 0`
`P1`	—	offset + elevation delta from the reference point	P4	`SideWideningWidth / 0-WideningWidthSlope`
`P0`	—	offset + elevation delta from the reference point	P1	`SideOverlayWidth / 0-OverlayWidthSlope`
`ES1`	—	horizontal delta, elevation taken from the target surface	P1	`0 / 0`
`ES0`	—	horizontal delta, elevation taken from the target surface	P0	`0 / 0`
`P2`	—	offset + elevation delta from the reference point	P1	`Side*D2/3000 / D2`
`P3`	—	offset + elevation delta from the reference point	P0	`0 / D3`
`P5`	ETW_Pave1	offset + elevation delta from the reference point	P4	`0 / 0-Pave1Depth`
`P6`	—	offset + elevation delta from the reference point	P1	`0-Side*Pave1Depth/3000 / 0-Pave1Depth`
`P8`	ETW_Pave2	offset + elevation delta from the reference point	P5	`0 / 0-Pave2Depth`
`P7`	—	offset + elevation delta from the reference point	P6	`0-Side*Pave2Depth/3000 / 0-Pave2Depth`
`P9`	ETW_Base	offset + elevation delta from the reference point	P8	`0 / 0-BaseDepth`
`P10`	—	offset + elevation delta from the reference point	P7	`0-Side*BaseDepth/3000 / 0-BaseDepth`
`P12`	ETW_Sub	offset + elevation delta from the reference point	P9	`0 / 0-SubbaseDepth`
`P11`	—	offset + elevation delta from the reference point	P10	`0-Side*SubbaseDepth/3000 / 0-SubbaseDepth`
