C3D UrbanReplaceCurbGutter1 — rehab curb+gutter tied to the sidewalk mark

At a glance


Kind	Subassembly (composed into an assembly)
Domain	Road
Civil 3D equivalent	`UrbanReplaceCurbGutter1`
Geometry	12 points, 11 links, 2 shapes
Conditional geometry	11 of the points are created inside a branch — which ones appear depends on the parameters and the target surface
Targets	1 (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
`FlangePointOffset`	number (metres unless the description says otherwise)	3	Attach to flange (m)
`MinSodSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.02	Sod slope used by the layout tie
`MaxSodSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.06	Steepest sod tie the clamp allows
`MaxMilling`	number (metres unless the description says otherwise)	0.0625	Deepest cut into the old flange before it is reported
`DesirableLift`	number (metres unless the description says otherwise)	0.0875	Lift of the new flange above the old surface (m)
`DimensionA`	number (metres unless the description says otherwise)	0.175	Flange to curb underside (m)
`DimensionB`	number (metres unless the description says otherwise)	0.4	Flange to flowline (m)
`DimensionC`	number (metres unless the description says otherwise)	0.025	Flowline depression (m)
`DimensionD`	number (metres unless the description says otherwise)	0.15	Curb rise (m)
`DimensionE`	number (metres unless the description says otherwise)	0.2	Flowline to curb back (m)
`DimensionF`	number (metres unless the description says otherwise)	0.15	Curb face width (m)
`DimensionG`	number (metres unless the description says otherwise)	0.325	Curb back drop (m)
`SubbaseDepth`	number (metres unless the description says otherwise)	0.45	Subbase depth at the flange (m)
`SubbaseExt`	number (metres unless the description says otherwise)	0.3	Subbase extension (m)
`SubbaseSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Subbase bottom slope (SE fallback)

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`	—	placed at the attachment point (an absolute offset/elevation)	—	`0 / 0`
`P11` conditional	—	horizontal delta, elevation taken from the target surface	P0	`Side*FlangePointOffset / 0`
`P1` conditional	Flange	offset + elevation delta from the reference point	P0	`SideFlangePointOffset / if(ExistingSurface.IsValid<0.5,SWY-MinSodSlope(abs(SideFlangePointOffset-SWX)-DimensionB-DimensionE)-DimensionD+DimensionC,min(max(P11.Y+DesirableLift-DimensionC+DimensionD,(SWY-(abs(SideFlangePointOffset-SWX)-DimensionB-DimensionE)MaxSodSlope)),(SWY-(abs(SideFlangePointOffset-SWX)-DimensionB-DimensionE)*MinSodSlope))+DimensionC-DimensionD)`
`P2` conditional	Flowline_Gutter	offset + elevation delta from the reference point	P1	`-Side*DimensionB / -DimensionC`
`P3` conditional	Top_Curb	offset + elevation delta from the reference point	P2	`-Side*(DimensionE-DimensionF) / DimensionD`
`P4` conditional	Back_Curb	offset + elevation delta from the reference point	P2	`-Side*DimensionE / DimensionD`
`P5` conditional	—	offset + elevation delta from the reference point	P4	`0 / -DimensionG`
`P6` conditional	—	offset + elevation delta from the reference point	P1	`0 / -DimensionA`
`P7` conditional	—	offset + elevation delta from the reference point	P1	`0 / -SubbaseDepth`
`P9` conditional	—	offset + elevation delta from the reference point	P6	`-Side(DimensionB+DimensionE+SubbaseExt) / (DimensionB+DimensionE+SubbaseExt)(DimensionA-DimensionC+DimensionD-DimensionG)/(DimensionB+DimensionE)`
`P8` conditional	—	offset + elevation delta from the reference point	P7	`0-Side(DimensionB+DimensionE+SubbaseExt-P9.Y/300) / (DimensionB+DimensionE+SubbaseExt-P9.Y/300)SubbaseSlope`
`P10` conditional	—	offset + elevation delta from the reference point	P0	`SWX / SWY`
