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

LeftWidth | number (metres unless the description says otherwise) | 3.6 | Left slab width (m) |
RightWidth | number (metres unless the description says otherwise) | 3.6 | Right slab width (m) |
LeftSlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.02 | Left cross slope (away) |
RightSlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.02 | Right cross slope (away) |
Pave1Depth | number (metres unless the description says otherwise) | 0.025 | Pave1 depth (m) |
Pave2Depth | number (metres unless the description says otherwise) | 0.025 | Pave2 depth (m) |
BaseDepth | number (metres unless the description says otherwise) | 0.1 | Base depth (m) |
SubBaseDepth | number (metres unless the description says otherwise) | 0.3 | Sub-base depth (m) |
DimensionA | number (metres unless the description says otherwise) | 0.81 | Barrier height (m) |
DimensionB | number (metres unless the description says otherwise) | 0.23 | Barrier top width (m) |
DimensionC | number (metres unless the description says otherwise) | 0.05 | Upper-face step (m) |
DimensionD | number (metres unless the description says otherwise) | 0.125 | Lower-face step (m) |
DimensionE | number (metres unless the description says otherwise) | 0.56 | Upper face height (m) |
DimensionF | number (metres unless the description says otherwise) | 0.18 | Lower face height (m) |
