Parameters
Defaults are the metric values the palette inserts. Every parameter can be driven by an expression or a target.
| Parameter | Type | Default | Meaning |
|---|
LeftGutterOffset | number (metres unless the description says otherwise) | -6 | Left Gutter of the existing pavement (m) |
RightGutterOffset | number (metres unless the description says otherwise) | 6 | Right Gutter of the existing pavement (m) |
MinimumOverlayDepth | number (metres unless the description says otherwise) | 0.1 | Overlay depth over the inner points (m) |
InsideMinSlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.01 | Flattest inside slope |
InsideMaxSlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.04 | Steepest inside slope (runtime check) |
OutsideMinSlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.02 | Flattest outside slope (runtime check) |
OutsideMaxSlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.06 | Steepest outside slope (runtime check) |
MaxBreakover | number (metres unless the description says otherwise) | 0.04 | Largest grade break at a quarter point |
MinCrownDeflection | number (metres unless the description says otherwise) | 0.05 | Smallest crown deflection kept |
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 |
EC | — | horizontal delta, elevation taken from the target surface | P0 | (LX+RX)/2 / 0 |
EL | — | horizontal delta, elevation taken from the target surface | P0 | (LX+(LX+RX)/2)/2 / 0 |
ER | — | horizontal delta, elevation taken from the target surface | P0 | (RX+(LX+RX)/2)/2 / 0 |
P3 | Crown | offset + elevation delta from the reference point | P0 | (LX+RX)/2 / if(ExistingSurface.IsValid>0.5,EC.Y+MinimumOverlayDepth,0) |
P2 | LaneBreak | offset + elevation delta from the reference point | P0 | (LX+(LX+RX)/2)/2 / if(ExistingSurface.IsValid>0.5,EL.Y+MinimumOverlayDepth,0-((LX+RX)/2-(LX+(LX+RX)/2)/2)*(0-InsideMinSlope)) |
P4 | LaneBreak | offset + elevation delta from the reference point | P0 | (RX+(LX+RX)/2)/2 / if(ExistingSurface.IsValid>0.5,ER.Y+MinimumOverlayDepth,0-((RX+(LX+RX)/2)/2-(LX+RX)/2)*(0-InsideMinSlope)) |
P1 | ETW | offset + elevation delta from the reference point | P0 | LX / LY |
P5 | ETW | offset + elevation delta from the reference point | P0 | RX / RY |
P6 | ETW_Overlay | offset + elevation delta from the reference point | P1 | 0 / 0 |
P7 | LaneBreak_Overlay | offset + elevation delta from the reference point | P2 | 0 / 0-MinimumOverlayDepth |
P8 | Crown_Overlay | offset + elevation delta from the reference point | P3 | 0 / 0-MinimumOverlayDepth |
P9 | LaneBreak_Overlay | offset + elevation delta from the reference point | P4 | 0 / 0-MinimumOverlayDepth |
P10 | ETW_Overlay | offset + elevation delta from the reference point | P5 | 0 / 0 |
