Lot Grade
C3D LotGrade — two grading planes meeting at a ridge hinge
At a glance
| Kind | Subassembly (composed into an assembly) |
| Domain | Miscellaneous |
| Civil 3D equivalent | LotGrade |
| Geometry | 3 points, 2 links, 0 shapes |
| Targets | 3 (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 |
InsideWidth | number (metres unless the description says otherwise) | 3.6 | Crown to hinge (m, MiddleOffset fallback) |
OutsideWidth | number (metres unless the description says otherwise) | 3.6 | Hinge to lot edge (m, EdgeOffset fallback) |
MinSlope | cross slope as a ratio (−0.02 = 2 % fall) | 0.01 | Minimum grading slope (both faces) |
EdgeHeight | number (metres unless the description says otherwise) | 0 | Lot edge elevation (m, EdgeElevation fallback) |
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 |
|---|---|---|---|---|
P1 | Crown | placed at the attachment point (an absolute offset/elevation) | — | 0 / 0 |
P2 | Hinge | offset + elevation delta from the reference point | P1 | Side*IW / max(IW*MinSlope,EH+OW*MinSlope) |
P3 | ETW | offset + elevation delta from the reference point | P1 | Side*(IW+OW) / EH |
