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
`CutGrade`	cross slope as a ratio (−0.02 = 2 % fall)	0.5	Cut daylight grade (rise/run)
`FillGrade`	cross slope as a ratio (−0.02 = 2 % fall)	0.25	Fill daylight grade
`ForeSlopeGrade`	cross slope as a ratio (−0.02 = 2 % fall)	0.25	Ditch foreslope grade
`ForeSlopeWidth`	number (metres unless the description says otherwise)	1.2	Ditch foreslope width (m)
`BottomWidth`	number (metres unless the description says otherwise)	0.6	Ditch bottom width (m)
`BackSlopeGrade`	cross slope as a ratio (−0.02 = 2 % fall)	0.25	Ditch backslope grade
`BackSlopeWidth`	number (metres unless the description says otherwise)	1.2	Ditch backslope width (m)
`MaxRun`	number (metres unless the description says otherwise)	30	Max daylight run (m)
`RoundingOption`	whole number / mode selector	0	0 = sharp catch, 1 = round it
`RoundingBy`	whole number / mode selector	0	0 = by arc length, 1 = by radius
`RoundingParameter`	number (metres unless the description says otherwise)	1.5	Arc length or radius (m)
`PlaceMaterial`	whole number / mode selector	3	3 = no lining
`SlopeLimit1`	cross slope as a ratio (−0.02 = 2 % fall)	1	First limit (rise/run)
`MaterialThickness1`	number (metres unless the description says otherwise)	0.3	Lining thickness past limit 1 (m)
`SlopeLimit2`	cross slope as a ratio (−0.02 = 2 % fall)	0.5	Second limit
`MaterialThickness2`	number (metres unless the description says otherwise)	0.15	Lining thickness past limit 2 (m)
`SlopeLimit3`	cross slope as a ratio (−0.02 = 2 % fall)	0.25	Third limit
`MaterialThickness3`	number (metres unless the description says otherwise)	0.1	Lining thickness past limit 3 (m)
`MaterialName1`	text	Rip Rap	Material named on the band past limit 1
`MaterialName2`	text	Rip Rap	Material named on the band past limit 2
`MaterialName3`	text	Rip Rap	Material named on the band past limit 3

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`	Hinge	placed at the attachment point (an absolute offset/elevation)	—	`0 / 0`
`DLF` conditional	Daylight_Fill	walk out at a slope until the target surface is met (daylight)	P0	`-FillGrade / Side*MaxRun`
`PF` conditional	Ditch_In	offset + elevation delta from the reference point	P0	`SideForeSlopeWidth / -ForeSlopeGradeForeSlopeWidth`
`PB` conditional	Ditch_Out	offset + elevation delta from the reference point	PF	`Side*BottomWidth / 0`
`PBS` conditional	—	offset + elevation delta from the reference point	PB	`SideBackSlopeWidth / BackSlopeGradeBackSlopeWidth`
`DLC` conditional	Daylight_Cut	walk out at a slope until the target surface is met (daylight)	PBS	`CutGrade / Side*MaxRun`
`RCG` conditional	—	horizontal delta, elevation taken from the target surface	DLC	`Side*abs(PBS.Offset-PB.Offset) / 0`
`RC_p1` conditional	Daylight,Slope_Link	placed at the attachment point (an absolute offset/elevation)	—	`DLC.Offset-(DLC.Offset-PBS.Offset)/RCL1RCPA / DLC.Y-(DLC.Y-PBS.Y)/RCL1RCPA`
`RC_p2` conditional	Daylight,Slope_Link	placed at the attachment point (an absolute offset/elevation)	—	`DLC.Offset+(RCG.Offset-DLC.Offset)/RCL2RCPB / DLC.Y+(RCG.Y-DLC.Y)/RCL2RCPB`
`ML1` conditional	—	offset + elevation delta from the reference point	PBS	`0 / 0-MT`
`ML2` conditional	—	offset + elevation delta from the reference point	DLC	`0 / 0-MT`
