MIDAS CIVIL NX tools (MIDAS IT Europe)

Undoes the latest point_to_patch_apply run (or the run named) with the plugin's cleanup: every PRES / BMLD row the run touched is put back as it was, the PATCH_ cases it removed are restored and the ones it created deleted. Previews unless apply: true.

Reads one table from the open CIVIL NX model the way the exporter's 'Preview this table' does and returns its first rows (default 20, max 200) with unit-labelled headers, any sub-tables (e.g. reaction totals) and the exact POST /post/TABLE Argument sent. Result tables are a quick sample (first 20 nodes/elements, 3 load cases, 2 stage steps) with an estimate of the full row count; model tables are read whole. When no loadCases are given it also lists the model's load-case names (loadCasesInModel). Read-only (GET /db and POST /post/TABLE only). Results need an analysed model.

Lists the CIVIL NX tables the Bulk Tabular Result Exporter plugin can export, with each one's id, MIDAS TABLE_TYPE or /db endpoint, components and the arguments it takes: analysis results (reactions, displacements, beam/truss/plate/solid forces and stresses, links, cables, tendons, modes, composite sections, construction stage tables, 'all columns' for any TABLE_TYPE), calculated pre-process tables, and every model data table (/db/NODE, ELEM, SECT, loads, stages, combinations…). Filter with scope, search or id. Needs no model. Use it to pick the table id for preview_result_table and export_result_tables.

Checks a cross-section's outlines with Section Designer's own rules (closed, not self-crossing, holes inside their outline, no overlaps, materials) and returns a PNG drawing of it — the outlines, numbered input vertices, the centroid and chain dimensions — plus the extents, areas and every vertex. Use it FIRST, and LOOK at the drawing: compare it with the user's sketch (overall width and depth, slab and web thicknesses, haunches, cells) and correct misreads before computing or writing anything. Needs no model. From a sketch: read every dimension and put the outline down as vertices in y (across, right +) and z (up), in the sketch's units (default mm). Holes are separate rings inside their outline; direction of travel does not matter. Rounded corners: fillet on that vertex; arcs between vertices: bulge; round bars or ducts: { circle }. Standard shapes can use a template (i_girder, box_girder) instead of vertices. Two materials (girder + slab): one part each, in construction order, each with its material.

Computes the full CIVIL NX property set of a section with Section Designer's solver: exact area, centroid, second moments, extreme fibres and perimeters from the outlines, and torsion J and shear areas ASY/ASZ from a finite-element mesh refined until all three settle to 0.5 % (converged: true). Composites (two or more parts) give each part alone (STIFF) and each construction stage transformed to the reference material (STIFF_SUM). Results use CIVIL's names (AREA, ASY, ASZ, RXX = J, RYY = Iyy, RZZ = Izz, …) in the section's units. Needs no model. Same section input as section_preview.

Without id: lists the model's sections (id, name, type, whether Section Designer can edit it) and the next free id. With id: returns a drawn section (VALUE/GEN, PSC/VALU, COMPOSITE-GEN) as outlines in section_preview's input format, in units (default mm), with its stored properties — edit it and write it back with section_write.

Writes a section into the open CIVIL NX model exactly as Section Designer's Write button does: VALUE/GEN, PSC/VALU or COMPOSITE-GEN with its computed properties (CIVIL keeps them as sent), in the model's units read at the time of writing, then reads it back and compares every value sent. id defaults to the model's next free section id. Refuses unconverged results. If the id is taken it writes nothing and says by what (and how many elements use it); replacing needs replaceExisting: true — DESTRUCTIVE, only with the user's agreement. Previews unless apply: true with confirmPlanHash. Before applying, show the user the drawing (section_preview) and the properties and get their go-ahead. section_write_undo reverses it. Same section input as section_preview.

Reverses a section_write run from the ledger: deletes the section it created (refused while elements use it), or writes back the section it replaced, then reads back. Default: the latest section_write run not yet undone. Previews unless apply: true.

Generates a bridge deck (beam grillage or plate mesh) with the Skew Grillage Geometry Generator plugin's own engine: skew, unequal girders, plan curvature, multi-span, crossfall and vertical profile, automatic transverse section sizing and structure groups (GIRDERS, CROSS-BEAMS, END-BEAMS for the support-line members, SPAN-n, or DECK for plates). Without apply it only previews (counts, metrics, groups, planHash). With apply: true it writes to CIVIL NX exactly as the plugin does: it refuses a model that already holds geometry unless replaceExisting is set, creates default material/sections/thickness where the ids are missing, and records the run for skew_grillage_undo.

Removes the deck a skew_grillage run wrote (its elements, nodes, new structure groups and any default properties nothing else uses). Refuses while lanes, other groups or other elements still depend on it. Previews unless apply: true.

Reads plate forces (PLATEFORCEUL, element local axes) for one orientation group and the given load cases, rotates them to the reinforcement direction and assesses every position with the plugin's own core (Denton, Wood-Armer, sandwich, Annex LL, CS 455). Returns counts, the worst elements with governing case/position, coverage and every gap (missing results are INCOMPLETE, never a pass). Read-only. Can take minutes on big models (a job on the website).

Calculation only: needs no model and changes nothing. Turns a slab's bar arrangement into the capacities the RC Slab & Shell Assessment routes need, with the plugin's own core. Use it to check a reinforcement layout by hand, or to see the capacities slab_assess will derive when given the same bars; to assess a model's plate forces use slab_assess (slab_explain_location for one element), and for a beam section cs455_assess. Give thickness_mm, fck and at least one face (top / bottom: cover_mm and one layer per bar direction); partial factors default to γc 1.5, γs 1.15, αcc 0.85, fyk 500 MPa. Returns per layer area, d, x, z, moment capacity (kNm/m) and force (kN/m), plus `assess` — ready to pass on: the Denton/Wood-Armer capacity pairs (top/bottom), the four Annex LL steel forces and the covers to the reinforcement centroid.

The working behind one element's utilisation: reads that element's plate forces, picks its governing position and case (or the one given) and re-runs it through the plugin's explain_location — every route, face, utilisation and intermediate quantity (gamma, Wood-Armer branch, sandwich layer forces, Annex LL split). Same inputs as slab_assess plus element. Read-only.

Reads the open model's plates (ELEM/NODE), structure groups, static cases and combinations (all LCOM tables) the way the RC Slab & Shell Assessment plugin does: orientation groups by plate normal (with a suggested in-plane reference direction) and every case with the sense it must be requested by. Read-only; use it before slab_assess.

The Stress Profile Generator's SLS report check (EN 1992-2 §7.2 concrete, EN 1993-2 §7.3 structural steel; normal stress σx at the fibres) over many elements × positions × combinations — or, with source stages, its construction-stage checks (fck(t) from CIVIL NX's concrete age, steel fy/γM0, tendons from CIVIL NX's tendon stresses). Every state is generated and matched with CIVIL NX as in stress_profile; composite parts are checked against their own concrete's fck. LIMITS ARE OPT-IN exactly as in the plugin: with no limit chosen the verdict is NO LIMIT APPLIED; nothing that could not be evaluated passes (INCOMPLETE). Combination categories (characteristic / frequent / quasi-permanent / none) are taken as given, else guessed from the name and reported. Returns the one verdict, the limits used, counts, the governing state, failures, what was not evaluated and why, per combination/stage and per element, and the plugin's SLS CSV as a download link. Read-only.

Creates structure groups with the Construction Stage Wizard plugin's group builder: pick a scope of elements, split it by rules (slice along X/Y/Z into n segments or at cuts, by section, material, element type, thickness, id ranges, existing groups), name them from a template, and resolve clashes with existing groups by policy. Typical use: segments of a deck for staged construction, e.g. rules [{kind:'slice', axis:'X', mode:'count', count:8, cuts:[]}] with naming {template:'Seg_{SLICE}'}. Previews unless apply: true; the write keeps a snapshot for stages_undo.

Restores the rows a stage_groups or construction_stages run changed, from the snapshot taken just before it wrote (the plugin's own restore). Default: the latest run not yet undone. Previews unless apply: true.

Reads what the Stress Profile Generator can show for chosen beam elements: each element's section (type, outline verified, composite parts, tapered), material, length, the load cases / combinations / envelopes CIVIL NX publishes results for (with kind and whether each is one concurrent state), the construction stages with results for that element (and, with stage, that stage's results such as Summation). Also lists the model's combinations with the SLS category the plugin would guess. Read-only; reads results with a few batched /post/TABLE requests. Use it before stress_profile or sls_stress_check.

The Stress Profile Generator's profile for ONE beam element: from CIVIL NX's beam forces and the true section outline it calculates σx (or σx from N / My / Mz, τ from Vz / Vy, von Mises, principal, Tresca) over the section at the chosen positions and loads, and checks every profile against CIVIL NX's own published stresses (effective PSC sections are drawn through CIVIL NX's stress points; composite sections part by part from CIVIL NX's per-part results; envelopes give CIVIL NX's values at the stress points plus the governing member or static part as a profile). Returns per profile: status (ok/unchecked/points/refused) with reasons, forces, extremes and where they occur, CIVIL NX vs calculated at stress points 1–4, per-part σx for composites, and min/max across the section at each depth. With `thermal` it gives the EN 1991-1-5 temperature stresses instead, split into total, restraint, self-equilibrating, uniform and linear parts (Type 3 heating/cooling with 100 mm surfacing, a user ΔT profile, or CIVIL NX's own section temperature; restraint free, full, axial, rotation, or CIVIL NX's forces of a load). Optional csv gives the plugin's CSV export as a download link. Read-only.
