Travel lane + pavement material
At a glance
| |
|---|
| Kind | Subassembly (composed into an assembly) |
| Domain | Road |
| Civil 3D equivalent | BasicLane |
| Geometry | 4 points, 2 links, 1 shapes |
| Targets | 1 (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 |
|---|
Side | +1 right of the baseline, −1 left | Right (+1) | +1 Right / -1 Left |
LaneWidth | number (metres unless the description says otherwise) | 3.5 | Travel lane width (m) |
LaneSlope | cross slope as a ratio (−0.02 = 2 % fall) | -0.02 | Lane cross slope |
PaveDepth | number (metres unless the description says otherwise) | 0.3 | Pavement depth (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 | Crown | placed at the attachment point (an absolute offset/elevation) | — | 0 / 0 |
ETW | ETW | horizontal delta from the reference, elevation from a slope | P0 | Side*LaneWidth / LaneSlope |
P0d | Datum | offset + elevation delta from the reference point | P0 | 0 / -PaveDepth |
ETWd | Datum | offset + elevation delta from the reference point | ETW | 0 / -PaveDepth |
Links
| Link | Code | Between | Role |
|---|
Top | Top | P0 → ETW | drawn |
Datum | Datum | P0d → ETWd | drawn |
