Parameters

Defaults are the metric values the palette inserts. Every parameter can be driven by an expression or a target.

Parameter	Type	Default	Meaning
`OverlayDepth`	number (metres unless the description says otherwise)	0.2	Overlay thickness (m)
`CrownOffset`	number (metres unless the description says otherwise)	0	Crown offset from the attach (m)
`LeftDefaultSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Left design cross slope
`RightDefaultSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Right design cross slope
`LeftOutsideEdgeOfExistingLane`	number (metres unless the description says otherwise)	3.6	Left existing lane outside edge (m)
`RightOutsideEdgeOfExistingLane`	number (metres unless the description says otherwise)	3.6	Right existing lane outside edge (m)
`LeftMinLevelDepth`	number (metres unless the description says otherwise)	0.3	Left levelling course (m)
`RightMinLevelDepth`	number (metres unless the description says otherwise)	0.3	Right levelling course (m)
`LeftMinMillDepth`	number (metres unless the description says otherwise)	0.1	Left mill back up from the levelling line (m)
`RightMinMillDepth`	number (metres unless the description says otherwise)	0.1	Right mill back up from the levelling line (m)
`LeftSlopeTolerance`	cross slope as a ratio (−0.02 = 2 % fall)	0.005	Left existing-slope tolerance
`RightSlopeTolerance`	cross slope as a ratio (−0.02 = 2 % fall)	0.005	Right existing-slope tolerance

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
`C`	Crown	placed at the attachment point (an absolute offset/elevation)	—	`CrownOffset / 0`
`L`	EOV	offset + elevation delta from the reference point	C	`0-LeftOutsideEdgeOfExistingLane / LeftDefaultSlope*abs(LeftOutsideEdgeOfExistingLane)`
`R`	EOV	offset + elevation delta from the reference point	C	`RightOutsideEdgeOfExistingLane / RightDefaultSlope*abs(RightOutsideEdgeOfExistingLane)`
`CO`	Crown_Overlay	offset + elevation delta from the reference point	C	`0 / 0-OverlayDepth`
`LO`	EOV_Overlay	offset + elevation delta from the reference point	L	`0 / 0-OverlayDepth`
`RO`	EOV_Overlay	offset + elevation delta from the reference point	R	`0 / 0-OverlayDepth`
`CL`	Crown_Milling	offset + elevation delta from the reference point	CO	`0 / 0-((LeftMinLevelDepth+RightMinLevelDepth)/2)`
`LL`	EOV_Milling_Outer	offset + elevation delta from the reference point	LO	`0 / 0-((LeftMinLevelDepth+RightMinLevelDepth)/2)`
`RL`	EOV_Milling_Outer	offset + elevation delta from the reference point	RO	`0 / 0-((LeftMinLevelDepth+RightMinLevelDepth)/2)`
`CM`	—	offset + elevation delta from the reference point	CL	`0 / ((LeftMinMillDepth+RightMinMillDepth)/2)`
`LM`	—	offset + elevation delta from the reference point	LL	`0 / ((LeftMinMillDepth+RightMinMillDepth)/2)`
`RM`	—	offset + elevation delta from the reference point	RL	`0 / ((LeftMinMillDepth+RightMinMillDepth)/2)`
