Parameters
Defaults are the metric values the palette inserts. Every parameter can be driven by an expression or a target.
| Parameter | Type | Default | Meaning |
|---|
Width | number (metres unless the description says otherwise) | 9 | Clear carriageway width (m) |
Height | number (metres unless the description says otherwise) | 5.5 | Clear height (m) |
Wall | number (metres unless the description says otherwise) | 0.5 | Lining 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 |
|---|
CL | Crown | placed at the attachment point (an absolute offset/elevation) | — | 0 / 0 |
IBL | Clear | offset + elevation delta from the reference point | CL | -Width/2 / 0 |
IBR | Clear | offset + elevation delta from the reference point | CL | Width/2 / 0 |
ITL | Clear | offset + elevation delta from the reference point | CL | -Width/2 / Height |
ITR | Clear | offset + elevation delta from the reference point | CL | Width/2 / Height |
OBL | Lining | offset + elevation delta from the reference point | CL | -Width/2-Wall / -Wall |
OBR | Lining | offset + elevation delta from the reference point | CL | Width/2+Wall / -Wall |
OTL | Lining | offset + elevation delta from the reference point | CL | -Width/2-Wall / Height+Wall |
OTR | Lining | offset + elevation delta from the reference point | CL | Width/2+Wall / Height+Wall |
