Parameters

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

Parameter	Type	Default	Meaning
`RailSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0	Cross slope of the whole track (cant)
`GaugeWidth`	number (metres unless the description says otherwise)	1.435	Track gauge (m)
`SleeperWidth`	number (metres unless the description says otherwise)	2.4	Sleeper length across the track (m)
`SleeperHeight`	number (metres unless the description says otherwise)	0.2	Sleeper depth (m)
`BallastWidth`	number (metres unless the description says otherwise)	3.6	Ballast top width (m)
`BallastDepth`	number (metres unless the description says otherwise)	0.3	Ballast depth (m)
`BallastSideSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.5	Ballast side slope (rise/run)
`SubballastWidth`	number (metres unless the description says otherwise)	6.6	Subballast top width (m)
`SubballastDepth`	number (metres unless the description says otherwise)	0.3	Subballast depth (m)
`SubballastSideSlope`	cross slope as a ratio (−0.02 = 2 % fall)	0.5	Subballast side slope (rise/run)

Points

Point codes are what feature lines, styles and quantity take-off match on — they are the contract this subassembly publishes.
