CS454 - Moving Load Wizard
cs454_moving_loadsIdempotent
CS 454 assessment live loading with the CS454 - Moving Load Wizard plugin's own engine: notional lanes laid out on the carriageway (line lanes on a grillage, surface lanes on a plate deck), the ALL model 1/2 vehicles up to the chosen level, SV/HB where picked, and the moving load cases with remaining areas — each written and read back. It reads the deck from the model the way the plugin does (reference girder, width, kerb, cross-beam group, skew) unless reference/surface/section.width are given. Without apply it only previews (lanes, vehicles, cases, blockers, planHash). With apply: true it writes, records the run for cs454_moving_loads_undo, and never overwrites lanes, vehicles or cases it did not write.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| apply | No | ||
| lanes | No | Lane options. Main one: picked — the loading models to lay out: M1S (ALL model 1 single), M1C (convoy), M2 (ALL model 2), SV, HB, SVM1S, SVM1C, SVM2, FW (footway), ACC (accidental). Also level, packing, svVehicle… | |
| scope | No | ALL = lanes + vehicles + cases; LANES = lanes only; LOADS = vehicles and cases on the model's existing lanes. | ALL |
| config | No | Advanced: any other plugin configuration field, deep-merged over the defaults. | |
| section | No | Carriageway cross-section, m: width, kerbOffset, markedLanes, hardShoulder, verges, footways, central reserve. width/kerbOffset are read from the deck if omitted. | |
| surface | No | Surface lanes: the alignment. mode GROUP (group), NODES (nodes) or RANGE (range). | |
| laneKind | No | Default: what the model suggests (beams -> LINE, plates -> SURFACE). | |
| readDeck | No | Read reference line, width, kerb offset, cross beams and skew from the deck. | |
| vehicles | No | Vehicle options. levels: assessment levels NORMAL, T26, T18, T7_5, T3, FE1, FE2 (lower levels are stacked in automatically); allModel1, allModel2, limitStates, svType… | |
| reference | No | Line lanes: the reference line. mode RANGE (range: element ids e.g. '1-10'), GROUP (group: structure group name) or NODES (nodes: [ids]). | |
| codeChange | No | Allow setting the moving load code to BS. Changing it from another code DELETES every lane in the model — only with the user's agreement. | |
| laneSource | No | NEW | |
| unitSwitch | No | Allow switching CIVIL NX to kN, m for the write and back afterwards (needed for non-SI models). | |
| writeOptions | No | Lane write options: loadDist LANE|CROSS, groupName (cross-beam group), moving BOTH|FORWARD|BACKWARD, skewStart, skewEnd. | |
| confirmPlanHash | No |
