Parameters

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

`DitchBottomThickness`	number (metres unless the description says otherwise)	0.5	Bottom lining thickness (m)
`IncreasedWallThickness`	number (metres unless the description says otherwise)	0.6	Extra inside-wall thickness at the bottom (m)
`InsideTaperedFaceDepth`	number (metres unless the description says otherwise)	2	Depth of the tapered inside face (m)
`InsideWallThickness`	number (metres unless the description says otherwise)	0.45	Inside wall thickness at top (m)
`DitchBottomWidth`	number (metres unless the description says otherwise)	2	Ditch bottom width (m)
`OutsideTaperedFaceWidth`	number (metres unless the description says otherwise)	0.6	Outside wall tapered face width (m)
`DitchDepth`	number (metres unless the description says otherwise)	2	Ditch depth (m)
`OutsideWallThickness`	number (metres unless the description says otherwise)	0.45	Outside wall thickness at top (m)
`InsideBenchWidth`	number (metres unless the description says otherwise)	1.5	Inside bench width (m)
`InsideBenchSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.04	Inside bench slope
`InsideBackslopeWidth`	number (metres unless the description says otherwise)	1	Inside backslope width (m)
`InsideBackslope`	cross slope as a ratio (−0.02 = 2 % fall)	1	Inside backslope (rise/run)
`InsideHingePointDepth`	number (metres unless the description says otherwise)	0	Inside hinge point depth (m)
`OutsideHingePointDepth`	number (metres unless the description says otherwise)	1	Outside hinge point depth (m)
`OutsideBackslopeWidth`	number (metres unless the description says otherwise)	1	Outside backslope width (m)
`OutsideBackslope`	cross slope as a ratio (−0.02 = 2 % fall)	1	Outside backslope (rise/run)
`OutsideBenchWidth`	number (metres unless the description says otherwise)	3	Outside bench width (m)
`OutsideBenchSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.04	Outside bench slope

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
`P10`	Ditch_In	placed at the attachment point (an absolute offset/elevation)	—	`0 / 0`
`P11`	—	offset + elevation delta from the reference point	P10	`SideInsideBackslopeWidth / -InsideBackslopeWidthabs(InsideBackslope)`
`P15`	—	offset + elevation delta from the reference point	P11	`SideInsideBenchWidth / -InsideBenchWidthabs(InsideBenchSlope)`
`P1`	Ditch_Back	offset + elevation delta from the reference point	P15	`SideInsideHingePointDepthIncreasedWallThickness/InsideTaperedFaceDepth / InsideHingePointDepth`
`P2`	Ditch_Face	offset + elevation delta from the reference point	P1	`Side*InsideWallThickness / 0`
`P3`	—	offset + elevation delta from the reference point	P2	`0 / -DitchDepth`
`P4`	—	offset + elevation delta from the reference point	P3	`Side*DitchBottomWidth / 0`
`P5`	Ditch_Face	offset + elevation delta from the reference point	P4	`Side*OutsideTaperedFaceWidth / DitchDepth`
`P6`	Ditch_Back	offset + elevation delta from the reference point	P5	`Side*OutsideWallThickness / 0`
`P7`	—	offset + elevation delta from the reference point	P1	`-Side*IncreasedWallThickness / -InsideTaperedFaceDepth`
`P8`	—	offset + elevation delta from the reference point	P7	`0 / -DitchBottomThickness`
`P9`	—	offset + elevation delta from the reference point	P6	`0 / -(InsideTaperedFaceDepth+DitchBottomThickness)`
`P12`	—	offset + elevation delta from the reference point	P6	`0 / -OutsideHingePointDepth`
`P13`	—	offset + elevation delta from the reference point	P12	`SideOutsideBenchWidth / OutsideBenchWidthabs(OutsideBenchSlope)`
`P14`	Ditch_Out	offset + elevation delta from the reference point	P13	`Sideif(OutsideBenchWidth<=0,0,OutsideBackslopeWidth) / if(OutsideBenchWidth<=0,0,OutsideBackslopeWidthabs(OutsideBackslope))`
