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)	0.1	Overlay thickness (m)
`LeftOverlayWidth`	number (metres unless the description says otherwise)	2	Overlay reach on the left (m)
`RightOverlayWidth`	number (metres unless the description says otherwise)	2	Overlay reach on the right (m)
`LeftSurfaceSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Left surface slope in preview
`RightSurfaceSlope`	cross slope as a ratio (−0.02 = 2 % fall)	-0.02	Right surface slope in preview
`RightSurfaceDrop`	number (metres unless the description says otherwise)	0	How far the right surface sits below the left (m)
`DimensionA`	number (metres unless the description says otherwise)	0.8	Barrier height (m)
`DimensionB`	number (metres unless the description says otherwise)	0.225	Barrier core width (m)
`DimensionC`	number (metres unless the description says otherwise)	0.05	Sloped face width (m)
`DimensionD`	number (metres unless the description says otherwise)	0.125	Toe width (m)
`DimensionE`	number (metres unless the description says otherwise)	0.55	Height of the sloped face (m)
`DimensionF`	number (metres unless the description says otherwise)	0.175	Toe height (m)
`LeftInsertOffset`	number (metres unless the description says otherwise)	0	Left insert point (m)
`RightInsertOffset`	number (metres unless the description says otherwise)	0	Right insert point (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`	—	placed at the attachment point (an absolute offset/elevation)	—	`0 / 0`
`P2`	—	offset + elevation delta from the reference point	P0	`0-MIR*BLW / 0`
`P6`	EOV_Overlay	offset + elevation delta from the reference point	P2	`0 / 0-abs(RightSurfaceDrop)`
`P1`	EOV	offset + elevation delta from the reference point	P2	`0-MIRLeftOverlayWidth / LeftOverlayWidthLeftSurfaceSlope`
`P5`	EOV	offset + elevation delta from the reference point	P6	`MIRRightOverlayWidth / RightOverlayWidthRightSurfaceSlope`
`P3`	EOV_Overlay	offset + elevation delta from the reference point	P1	`0 / 0-OverlayDepth`
`P4`	—	offset + elevation delta from the reference point	P2	`0 / 0-OverlayDepth`
`P7`	EOV_Overlay	offset + elevation delta from the reference point	P5	`0 / 0-OverlayDepth`
`P8`	—	offset + elevation delta from the reference point	P6	`0 / 0-OverlayDepth`
`P9`	Barrier	offset + elevation delta from the reference point	P2	`0 / H29`
`P10`	Barrier	offset + elevation delta from the reference point	P9	`MIR*DimensionD / DimensionF`
`P11`	Barrier	offset + elevation delta from the reference point	P10	`MIR*DimensionC / DimensionE`
`P12`	Barrier	offset + elevation delta from the reference point	P11	`MIR*DimensionB / 0`
`P13`	Barrier	offset + elevation delta from the reference point	P0	((P12.Y-P0.Y)+if(RightSurfaceDrop>=0,1,-1)(DimensionE/DimensionC)(P12.Offset-P0.Offset)-DimensionA+DimensionE-(P6.Y-P0.Y)-MIRif(RightSurfaceDrop>=0,RightSurfaceSlope,LeftSurfaceSlope)(if(RightSurfaceDrop>=0,1,-1)DimensionD-(P6.Offset-P0.Offset)))/(if(RightSurfaceDrop>=0,1,-1)(DimensionE/DimensionC)+MIRif(RightSurfaceDrop>=0,RightSurfaceSlope,LeftSurfaceSlope)) / (P12.Y-P0.Y)-MIR(DimensionE/DimensionC)((((P12.Y-P0.Y)+if(RightSurfaceDrop>=0,1,-1)(DimensionE/DimensionC)(P12.Offset-P0.Offset)-DimensionA+DimensionE-(P6.Y-P0.Y)-MIRif(RightSurfaceDrop>=0,RightSurfaceSlope,LeftSurfaceSlope)(if(RightSurfaceDrop>=0,1,-1)DimensionD-(P6.Offset-P0.Offset)))/(if(RightSurfaceDrop>=0,1,-1)(DimensionE/DimensionC)+MIRif(RightSurfaceDrop>=0,RightSurfaceSlope,LeftSurfaceSlope)))-(P12.Offset-P0.Offset))
