Domain	Road
Civil 3D equivalent	`DaylightRockCut`

Conditional geometry	15 of the points are created inside a branch — which ones appear depends on the parameters and the target surface
Targets	2 (surface / offset / elevation targets this subassembly can be linked to)

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
`CutSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.5	Cut daylight grade, no rock (rise/run)
`FillSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.25	Fill daylight grade
`ForeSlopeSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.25	Ditch foreslope grade
`DitchDepth`	number (metres unless the description says otherwise)	1.2	Ditch depth (m)
`BottomWidth`	number (metres unless the description says otherwise)	0.6	Ditch bottom width (m)
`BackSlopeSlope`	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)
`RockCut1DepthLimit`	number (metres unless the description says otherwise)	2.7	Max rock depth for slope 1 (m)
`RockCut1Slope`	cross slope as a ratio (−0.02 = 2 % fall)	0.25	Rock cut grade within the limit
`RockCut2Slope`	cross slope as a ratio (−0.02 = 2 % fall)	1	Rock cut grade beyond the limit
`EGStrippingWidth`	number (metres unless the description says otherwise)	1.5	Stripping bench width on the rock (m)
`DaylightLinkSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.5	Daylight grade above the rock
`OmitDaylightLink`	on / off	off	1 = no daylight wing
`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)

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`
`PF` conditional	Ditch_In	offset + elevation delta from the reference point	P0	`Side*(DitchDepth/ForeSlopeSlope) / -DitchDepth`
`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 / BackSlopeWidthBackSlopeSlope`
`RP` conditional	—	horizontal delta, elevation taken from the target surface	PBS	`0 / 0`
`R` conditional	—	walk out at a slope until the target surface is met (daylight)	PBS	`RockCut1Slope / Side*60`
`R` conditional	—	walk out at a slope until the target surface is met (daylight)	PBS	`RockCut2Slope / Side*60`
`S` conditional	Daylight_Strip	offset + elevation delta from the reference point	R	`Side*(if(RockSurface.IsValid, EGStrippingWidth, 0)) / 0`
`DL` conditional	Daylight,Daylight_Cut	walk out at a slope until the target surface is met (daylight)	S	`if(RockSurface.IsValid, DaylightLinkSlope, CutSlope) / Side*30`
`GDRC` conditional	—	horizontal delta, elevation taken from the target surface	DL	`Side*abs(DL.Offset-S.Offset) / 0`
`RDRC_p1` conditional	Daylight	placed at the attachment point (an absolute offset/elevation)	—	`DL.Offset-(DL.Offset-S.Offset)/RDRCL1RDRCPA / DL.Y-(DL.Y-S.Y)/RDRCL1RDRCPA`
`RDRC_p2` conditional	Daylight	placed at the attachment point (an absolute offset/elevation)	—	`DL.Offset+(GDRC.Offset-DL.Offset)/RDRCL2RDRCPB / DL.Y+(GDRC.Y-DL.Y)/RDRCL2RDRCPB`
`DL` conditional	Daylight,Daylight_Fill	walk out at a slope until the target surface is met (daylight)	P0	`-FillSlope / Side*30`
`GDRF` conditional	—	horizontal delta, elevation taken from the target surface	DL	`Side*abs(DL.Offset-P0.Offset) / 0`
`RDRF_p1` conditional	Daylight	placed at the attachment point (an absolute offset/elevation)	—	`DL.Offset-(DL.Offset-P0.Offset)/RDRFL1RDRFPA / DL.Y-(DL.Y-P0.Y)/RDRFL1RDRFPA`
`RDRF_p2` conditional	Daylight	placed at the attachment point (an absolute offset/elevation)	—	`DL.Offset+(GDRF.Offset-DL.Offset)/RDRFL2RDRFPB / DL.Y+(GDRF.Y-DL.Y)/RDRFL2RDRFPB`
