Parameters
Defaults are the metric values the palette inserts. Every parameter can be driven by an expression or a target.
| Parameter | Type | Default | Meaning |
|---|---|---|---|
LaneWidth | number (metres unless the description says otherwise) | 3.65 | Travel lane width (m) |
ShoulderWidth | number (metres unless the description says otherwise) | 3 | Paved shoulder width (m) |
MedianHalf | number (metres unless the description says otherwise) | 2 | Half the centre median (m) |
LaneSlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.02 | Lane cross slope |
ShoulderSlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.04 | Shoulder cross 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 |
|---|---|---|---|---|
CL | Crown | placed at the attachment point (an absolute offset/elevation) | — | 0 / 0 |
MED_R | Median | horizontal delta from the reference, elevation from a slope | CL | MedianHalf / 0 |
ETW_R1 | ETW | horizontal delta from the reference, elevation from a slope | MED_R | LaneWidth / LaneSlope |
ETW_R2 | ETW | horizontal delta from the reference, elevation from a slope | ETW_R1 | LaneWidth / LaneSlope |
EPS_R | EPS | horizontal delta from the reference, elevation from a slope | ETW_R2 | ShoulderWidth / ShoulderSlope |
MED_L | Median | horizontal delta from the reference, elevation from a slope | CL | -MedianHalf / 0 |
ETW_L1 | ETW | horizontal delta from the reference, elevation from a slope | MED_L | -LaneWidth / -LaneSlope |
ETW_L2 | ETW | horizontal delta from the reference, elevation from a slope | ETW_L1 | -LaneWidth / -LaneSlope |
EPS_L | EPS | horizontal delta from the reference, elevation from a slope | ETW_L2 | -ShoulderWidth / -ShoulderSlope |
