| Geometry | 7 points, 6 links, 1 shapes |
| Targets | 4 (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 |
|---|
LeftEdgeOffset | number (metres unless the description says otherwise) | -3.6 | Left edge of the existing pavement (m) |
RightEdgeOffset | number (metres unless the description says otherwise) | 3.6 | Right edge of the existing pavement (m) |
CrownHeight | number (metres unless the description says otherwise) | 0.1 | Crown lift above the edge midpoint (m) |
MinSlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.01 | Flattest cross slope allowed |
MaxSlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.03 | Steepest cross slope allowed |
OverlayDepth | number (metres unless the description says otherwise) | 0.1 | Overlay thickness (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 |
P1 | ETW | offset + elevation delta from the reference point | P0 | LX / LY |
P3 | ETW | offset + elevation delta from the reference point | P0 | RX / RY |
P2 | Crown | offset + elevation delta from the reference point | P0 | (LX+RX)/2 / CY |
P4 | ETW_Overlay | offset + elevation delta from the reference point | P1 | 0 / 0-OverlayDepth |
P5 | Crown_Overlay | offset + elevation delta from the reference point | P2 | 0 / 0-OverlayDepth |
P6 | ETW_Overlay | offset + elevation delta from the reference point | P3 | 0 / 0-OverlayDepth |
