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) |
LeftOverlaySlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.02 | Left surface slope in preview |
RightOverlaySlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.02 | Right surface slope in preview |
DimensionB | number (metres unless the description says otherwise) | 0.75 | Barrier core width (m) |
DimensionC | number (metres unless the description says otherwise) | 0.05 | Barrier step, each side (m) |
DimensionD | number (metres unless the description says otherwise) | 0.125 | Barrier toe, each side (m) |
SlopeTolerance | cross slope as a ratio (−0.02 = 2 % fall) | 0.05 | How close a sampled slope must be to be kept |
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 |
|---|
P2 | — | placed at the attachment point (an absolute offset/elevation) | — | 0-(DimensionB+2*DimensionC+2*DimensionD)/2 / 0 |
P6 | — | offset + elevation delta from the reference point | P2 | BW / 0 |
P1 | EOV | offset + elevation delta from the reference point | P2 | 0-LeftOverlayWidth / LeftOverlayWidth*LeftOverlaySlope |
P5 | EOV | offset + elevation delta from the reference point | P6 | RightOverlayWidth / RightOverlayWidth*RightOverlaySlope |
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 |
