civil-nx
Registry code: be0c909db30defa5
Tools that build, check and report on a MIDAS CIVIL NX model through the engines of the MIDAS IT Europe plugins. Each tool runs the same code as its plugin, so the plugin's rules and checks — verified against live CIVIL NX — apply.

- Is civil-nx live?
- Yes — it answered the hub's last check (checked 13h ago). It answered 100% of checks over the last 30 days.
- Is civil-nx free to use?
- Partly — some of its tools are open, others need a key or payment.
- What tools does civil-nx have?
- 107 tools: b2p_undo, bridge_reshape_undo, bridge_thermal_read, bridge_thermal_remove, concurrent_forces_setup, concurrent_forces_probe, cs454_moving_loads_read, cs454_moving_loads, ….
- Is civil-nx safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
bridge_thermal_calc open 13h ago
Calculates bridge temperature actions with the Bridge Thermal Loads plugin's own engine: shade air and effective bridge temperatures, the uniform ranges ΔT_N,con / ΔT_N,exp (and bearing ranges), the vertical temperature difference (linear Approach 1 or the non-linear code profile, as depth/temperature points), CS 454 / BS 5400 combined X − Y values, and the simultaneity combinations, each with its clause. Codes: EN 1991-1-5 + UK NA (default) or CEN, CS 454, BS 5400-2:2006 / 1978. Needs no model.

Reads the model the way the Beam to Plate plugin (1.0.6) does and studies every section the chosen beams use, against CIVIL NX's own published properties (/ope/SECTPROP): whether the outline was READ correctly (A/Iyy/Izz vs published) and how far the PLATE model sits from it, the verdict (converts / blocked / not read, with the reason), the plugin's plate-or-solid suggestion with the mesh a solid would need, material slots of composite parts, the model's length/force units, the beams that cannot be converted and why, and an element estimate for the mesh. Choose beams with ONE of elementIds, sections, groups or useCivilSelection (default: every beam). Read-only; on the website it runs as a background job (poll job_status).

Reads the open model the way the Bridge Reshaper plugin (1.0.6) does: the deck (straight, in straight pieces kinked at half-joints or piers, or curved; beam girders, girders meshed as plates, or a spine (single-line) model with its pylons, stays and piers read as substructure; any length unit), its spans, supports and skews (Abutment A, Pier 1…, Abutment B, skew in degrees from square), girder/edge lines, bearings and substructure assemblies, its direction (tightest radius on a curve) and its levels (level at each abutment, grade, cross slope), with a plan drawing. Read-only; on the website it runs as a background job (poll job_status). Use it before bridge_reshape.

Default: found from the model." } }, "additionalProperties": false }arguments 46 linesb2p_undo unknown never probed
Undoes a b2p_convert run from the ledger with the plugin's own Undo: removes the virtual beams, the plates/solids, the rigid links and construction-joint links, the converted loads and the nodes it made, gives the stages and boundary groups back, then puts the beams back with their beam loads, temperatures, releases, offsets, moved nodal loads and structure-group membership, and reads the model back. Resumable: if CIVIL NX refuses some deletes or the connection goes, the call says what is left and calling again with the same runId carries on (also after a background job that stopped). Afterwards (tidy, default on) it also removes the thickness records and the 'B2P mesh' group the run created when nothing uses them — the plugin's own Undo leaves both. Default run: the latest not undone. Previews unless apply: true; on the website the apply runs as a background job.
{ "type": "object", "properties": { "tidy": { "type": "boolean", "default": true, "description": "Also remove the thickness records and mesh group this run created, when unused." }, "apply": { "type": "boolean", "default": false }, "runId": { "type": "string", "description": "Ledger run id; default = the latest b2p_convert run not yet undone." } }, "additionalProperties": false }arguments 19 linesbridge_reshape_undo unknown never probed
Undoes a bridge_reshape run from the ledger with the plugin's own Undo: every row the run overwrote is written back and every row it created is removed, so the model returns exactly. Refuses on a different model, or when the model was edited since the apply (force: true undoes anyway, overwriting those edits). Resumable: a step that fails is reported and calling again retries only what is left. Default run: the latest not undone. Previews unless apply: true; on the website the apply runs as a background job.
{ "type": "object", "properties": { "apply": { "type": "boolean", "default": false }, "force": { "type": "boolean", "default": false, "description": "DESTRUCTIVE: undo even though the model was edited since the apply (those edits are overwritten)." }, "runId": { "type": "string", "description": "Ledger run id; default = the latest bridge_reshape run not yet undone." } }, "additionalProperties": false }arguments 19 linesbridge_thermal_read unknown never probed
Reads the open model the way the Bridge Thermal Loads plugin does: the deck from a structure group, element list or the CIVIL NX selection, grouped into sections (beams by section, plates by thickness), each with the proposed deck type, depths h and D, and its width-against-depth parts per material (read through the shared section library; catalogue sections from CIVIL NX's published properties). Also the units, the initial temperature and any EC1T_ cases already in the model. Read-only.
{ "type": "object", "properties": { "group": { "type": "string", "description": "Structure group holding the deck elements." }, "elementIds": { "type": "array", "items": { "type": "integer" } }, "useSelection": { "type": "boolean", "description": "Use the elements selected in CIVIL NX (when neither group nor elementIds is given)." } }, "additionalProperties": false }arguments 20 linesbridge_thermal_remove unknown never probed
Removes what the Bridge Thermal Loads plugin writes: every load case whose name starts with EC1T_ (also named sets and ones the plugin window wrote) and all temperature loads in them, on any element. Other load cases are not touched. An undo record is kept, so bridge_thermal_undo can put them back. Previews unless apply: true.
{ "type": "object", "properties": { "apply": { "type": "boolean", "default": false } }, "additionalProperties": false }arguments 10 linesconcurrent_forces_setup unknown never probed
Concurrent Force Reporter, step 1. Reads the open CIVIL NX model the way the plugin does when it connects and lists what a concurrent-forces run can use: every load case and combination (all ten LCOM tables) with how MIDAS addresses it, whether it is envelope-valued, and whether it is AVAILABLE — moving load, settlement, response spectrum, ABS and SRSS (anywhere down the combination tree) cannot give a coexistent state and are listed with the reason and the workaround; the items the model has per result source (beam/truss/plate elements, general/elastic links, node reactions/displacements); the key effects available for them (keyEffect ids such as BEAM:Moment-y, REACTION:FZ, ELASTICLINK:Axial, with units); structure groups (element and node ranges, links found on their nodes); construction stages with their step tokens; criteria and output positions; the model's units; whether results are published. Read-only. Use search to narrow a long case list; includeConstituents shows each combination's children.

Concurrent Force Reporter diagnostics. For each result source the plugin reads (beam, truss, plate, general link, elastic link, node reaction, node displacement), asks this CIVIL NX build with one item of that kind which table token answers, the columns it returns and how they map, the output-point tokens, and the result series published. Use it when concurrent_forces reports a missing table, column or series. Read-only.

Read-only: changes nothing in the model. Call it before cs454_moving_loads to see what the CS454 - Moving Load Wizard would do. Returns: existing (the lanes, vehicles, cases and groups already in the model, each marked if an earlier cs454_moving_loads run created it); laneKindSuggestion (LINE for beams, SURFACE for plates); deckRead (reference girder or plate edge, width, kerb offset, cross-beam group, skew — narrowed by deckFilter, reversed by trafficOtherWay); the lanes and cases the given settings would produce; config (the plugin's own settings file — pass it back as configFile); options (valid loadings, vehicles and Irish Rail trains). Takes the same inputs as cs454_moving_loads; the write permissions (codeChange, unitSwitch) only change which blockers are listed.

Start here when the user shares a reinforcement drawing, photo or schedule. Read from it: cover, for each face the layers (number of bars or spacing, and Ø - mm, inches or #US sizes are all accepted), side bars, links (Ø, legs, spacing); then call this tool. It reads one beam section from the open model through the shared MIDAS section library (outline checked against CIVIL NX's published properties), places the bars with the CS 455 plugin's own placement (cover to every edge) and RETURNS A DRAWING of the section with every bar placed - compare it with the user's drawing and correct rebar until they match (ask the user about anything the drawing does not show, e.g. cover). Then cs455_export_calc_sheet gives the report. Also returns what the plugin's engine derives: area, centroid, depth, usable_for_capacity, parts, the bars placed per schedule row (or why a row failed), and the model's concrete grade. Read-only.

Imports a DXF into the open CIVIL NX model with the Advanced DXF Importer plugin's engine: the same parse, layer mapping, clean-up and write as the plugin. Nodes and elements get new ids above the model's (existing rows are never overwritten); each layer's structure group is created or added to; blank properties become the plugin's DXF default material (C40/50), section (SB 500x300) and thickness (250), created or reused by name. Previews by default (writes nothing): the plan with id ranges, groups, default properties and any unit switch. To write, call again with the same inputs, apply: true and confirmPlanHash; the model is read again and the write refused if the plan changed. The write creates a master group DXF_<file> #<token> first, then the unit change, properties, nodes, elements and groups, then reads everything back to verify. The import journal is recorded so dxf_import_undo can remove exactly what it created, even after a partial failure. Inputs as for dxf_inspect, plus mergeExisting.

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.

Load Combination Contribution Analyzer, step 1. Without name: lists the model's General-tab load combinations (LCOM-GEN) with type (ADD, ENVELOPE, ABS, SRSS), constituent count, whether it is a max/min pair, and whether it can be decomposed (refused: time-history, unknown analysis type, undefined constituents, self-reference, a constituent whose type differs from the case of that name) — plus the result tables the model has items for (BEAM, TRUSS, PLATE, ELASTICLINK, GENLINK, REACTION, DISPLACEMENT) with their components and units, structure groups, construction stages and the model's units. With name: that combination's full tree (nested combinations, factors, kinds), the effective factor of every load case over all Add paths (a case reached down several branches gets the sum of the path products), and the envelopes / ABS / SRSS inside it.

Runs the Model Report plugin's fourteen quality checks on the open CIVIL NX model: duplicate (coincident) nodes, orphan nodes, zero-length and duplicate elements, elements without material/section, unused properties, disconnected regions, support adequacy, load cases with no loads, loads on missing nodes/elements, combinations citing a missing case, elements in no structure group, length outliers and end releases that make a mechanism. Returns each check's result (pass / fail / not applicable / not run), severity, criterion, count and the ids involved, a model summary (counts, units) and what was read from each table. Reads only the tables the checks use (GET only). Read-only; on the website it runs as a job.

Builds the Model Report plugin's 'Model report' for the open CIVIL NX model — cover, contents, materials, sections (with drawings), supports and springs, load cases, combinations and loads, nodes/elements/groups appendix, cross sections, tendons, CIVIL NX pictures, the QC checks and the data sources read — and returns it as download links: html (default), xlsx, docx and/or pdf, in English, French, German, Greek or Polish. Document details (project, client, job no., revision, author, checker, date …) go on the cover. Pictures are rendered by CIVIL NX (POST /view/CAPTURE, the user's own view is left as it is): by default the isometric model view and every figure saved in the model; choose model views, load views, saved figures and beam diagrams with `images` (model_report_images lists them), and the beam diagrams' legend format (exponential/fixed, decimals) there too. Otherwise reads only (GET, plus POST /post/TABLE for tendon coordinates). Runs as a job.

Exports the open CIVIL NX model to IFC with the Model to IFC plugin: real section outlines with voids, smooth tapers, tendons, composite deck slabs, materials, structure groups and stages; in IFC4.3 also the bridge structure (deck, piers, abutments, bearings, alignment); optionally the structural analysis model with loads, combinations, support reactions, and — for the series named in resultSeries — node displacements and member/plate forces; optionally a second file of the deformed shape for one load case or combination. Only reads the model. Returns download links (never the file inline) and the exporter's report (sections, volumes, bridge parts, checks).

Converts the model's point loads (or a coordinate table) into dispersed patch loads with the Point to Patch Convertor's engine and writes them as PATCH_<case> load cases: plate decks get pressures on the plates the patch covers, grillages get UDLs on the members by the lever rule, total force conserved; units converted to the model's. The writer snapshots every row it touches, writes, and reads every item back with a force-equilibrium check. Previews unless apply: true.

The fast way to add supports, point springs, beam end releases, self-weight, nodal loads, beam UDLs, plate pressures and element temperatures: describe WHERE (structure group, id ranges, a line, a box, a coordinate, or the extreme nodes of a group) and WHAT, and the tool finds the nodes / elements and builds the CONS, CNLD, BMLD and PRES rows itself — no table lookup, no reading NODE / ELEM, no rows to write. Values are in kN and m by default (units: { force, length }) and converted to the model's units; signs follow the global axes (w: -10 with dir GZ = 10 kN/m downward). Missing load cases (STLD), load groups and boundary groups are created. Examples: supports [{ at: { group: "GIRDERS", pick: "xmin" }, type: "pinned" }, { at: { group: "GIRDERS", pick: "xmax" }, type: "roller-x" }]; udl [{ on: { group: "GIRDERS" }, case: "SIDL", w: -12.5 }]; udl with range { axis: "x", from: 10, to: 20 } loads only that stretch; nodalLoads [{ at: { nodes: "101to121by2" }, case: "Wheel", F: [0, 0, -50] }]; pressure [{ on: { group: "DECK" }, case: "Surfacing", p: -2.4 }]; springs [{ at: { group: "PIERS", pick: "zmin" }, k: [1e5, 1e5, 5e5] }]; releases [{ on: { group: "CROSS-BEAMS" }, free: "My Mz" }]; selfWeight [{ case: "SW" }]; temperature [{ on: { group: "DECK" }, case: "T+", uniform: 15, gradientZ: 10 }]. The preview is a summary — counts, ids, and total force per load case to check against the intended load. Apply with apply: true and confirmPlanHash; every row is read back. Undo with civil_write_tables_undo (same ledger). Rules kept for you: CIVIL NX keeps one nodal load per case per node, so loads landing on the same node and case are summed (also with an existing one, with a warning); an existing support on a node is replaced; existing beam loads and pressures are kept and the new ones added.

Exports one or more CIVIL NX tables (each like the preview_result_table arguments, full scope, no sampling) into one Excel workbook built by the exporter plugin: one sheet per table (and per sub-table; split above 1,048,575 rows), unit-labelled headers, numeric cells, and a 'Contents & Export Log' sheet listing each table's request, rows and any failure. format csv gives one CSV file per sheet instead. Returns download links (never the file inline) and a per-table summary; a table that fails is logged and the rest still export. Read-only.

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.

Without id: lists the model's sections (id, name, type, whether Section Designer stores it as outlines) and the next free id. With id: returns the section as outlines in section_preview's input format, in units (default mm). A drawn section (VALUE/GEN, PSC/VALU, COMPOSITE-GEN) comes back with its stored properties; any other type (DB/User shapes, PSC guide-curve sections, steel girders with stiffeners and riveted angles, composite girders, tapered) is rebuilt by the section library and checked against the properties CIVIL NX published, with a note saying what was recovered — edit it and write it back with section_write.

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}'}.

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).

Puts every row a civil_write_tables run touched back as it was before the run: deletes rows it created, restores rows it changed or deleted (a merging table's row is replaced whole). Works on a run that stopped part-way too. Warns where a row changed after the run. What CIVIL NX deleted along with a row (elements on a deleted node, loads on a deleted element) is not part of the run and does not come back. Default: the latest run not yet undone.

Runs the CIVIL NX analysis of the open model (doc/ANAL), so results can be read with the result tools straight after building or changing a model. Replaces the model's results; changes no model data. The model must have been saved to a file at least once (the API cannot analyse an unsaved model): saveFirst: true saves it over its file first. Previews unless apply: true.

Writes a tendon_design result into the open model with the Tendon Designer plugin's writer: the strand material and tendon property (or one already in the model), every tendon profile (TDNA) and its prestress (TDPL) in the prestress load case, one load group per tendon group, and - when a construction stage is named - each group's load group activated in its stage. With improve, the model's own tendons the design was read from are removed first (only while unchanged since). Refused when the model, the girder, or the loads the forces were read from changed, and while checks fail unless allowFailedChecks. The model is re-checked before writing, the journal is kept before the first change, and every row is read back. Previews unless apply: true.

Undoes the latest tendon_write (or the run named), newest first: removes the tendons, prestress, property, material, load case and load groups it created, puts back the model tendons it removed, and takes its load groups out of the construction stages.

Reads a DXF with the Advanced DXF Importer plugin's own parser and clean-up and reports what an import would create: the file (version, encoding, entity counts, what is ignored or unsupported), its units, every layer with its entities and mapping, and the clean model — nodes, BEAM/TRUSS/PLATE elements per layer, structure groups, disconnected parts, and the clean-up operations (merged nodes, removed duplicates and zero-length segments, splits at crossings and T-junctions, hanging nodes). Needs no CIVIL NX model and changes nothing. Give the drawing as dxfText, dxfBase64 or url (4 MB inline, 25 MB by url). Use it to choose the mapping and settings before dxf_import.

Builds a construction stage sequence with the Construction Stage Wizard plugin's bulk generator and writes it with its stage planner (which keeps composite sections and construction-stage load combinations intact, rewriting and restoring them when CIVIL NX would otherwise delete them). Structure groups are activated in order, groupsPerStage at a time; boundary and load groups (e.g. supports, self weight) ride in the first new stage; an optional temporary group per stage (e.g. a form traveller) is switched on and off with it; an optional final stage closes the sequence. mode 'append' adds after the model's existing stages; 'replace' replaces them all.

Creates one structure group per section, per material, or per section + material pair, with the Auto Structure Groups plugin's own engine: it reads every element's section and material, names each group from the prefix and the section/material names (cleaned and cut to 40 characters, as in the plugin; elements with no section/material go to <prefix>UNASSIGNED), largest group first. Optional: include each group's nodes, skip groups with fewer than minElements elements, or write only the groups named in groups. A name that already exists is skipped unless existing: 'overwrite' — and then this run's members are ADDED to that group (CIVIL NX merges a write into an existing group; it never removes members). Previews unless apply: true with confirmPlanHash; the plugin's writer re-reads db/GRUP, writes in batches and checks the read-back. auto_structure_groups_undo reverses it.

Converts beam elements into a plate (or solid) mesh of their cross-section with the Beam to Plate plugin's own engine (1.0.6): every section CIVIL NX gives geometry for (rolled/fabricated steel, PSC, boxes, composite, tapered groups, VALUE, catalogue), solid concrete sections as a grid of plates or as solids, exact beam loads / nodal loads / temperatures moved onto the mesh, haunches, diaphragms, deck slabs joined, rigid links to whatever else meets the beam's nodes (staged per construction stage), virtual beams per row of plates, groups and composite casting stages carried across. Previews by default (totals, volume check, per-section verdict, notes, what is left behind such as tendons or lanes, problems, planHash) and writes nothing. With apply: true and confirmPlanHash it re-reads the model, refuses if the plan changed, and writes the plugin's way: nodes, thicknesses and elements written and read back, then links, loads, groups, stages, virtual beams, and only then the source beams deleted (deleteSourceBeams); a write that fails part way is rolled back by the plugin. The run is recorded for b2p_undo. Lengths are in the model's unit. Use b2p_survey first. Runs as a background job on the website (poll job_status).

Changes the geometry of the bridge in the open model in place, with the Bridge Reshaper plugin's own engine (1.0.6): new span lengths (the deck is stretched - each span keeps its element count), a skew for each support, a new horizontal alignment (straight, segments, fitted points, LandXML/DXF) and new deck levels (flat, grades with parabolic vertical curves, one-way or crowned cross slope). crossMembers 'parallel' (default) moves nodes only - every element, node, load, group, stage and lane keeps its id; 'square' re-meshes the deck with cross members square to the girders running on to the skewed support lines (straight decks of beam girders only, not with new levels). Loads, structure groups, construction stages, lanes, tapered groups and links follow the deck; beam loads in global axes, plane loads and lane end skews are turned with it; piers and abutments follow their supports ('follow' the skew, or 'rigid' keep their shape).

Concurrent Force Reporter, step 2. For a set of items (elements, nodes, links), finds the load state that makes ONE key effect extreme at ONE key item (max, min or absolute max over the selected load cases and combinations, at every output point), then reports every item's results IN THAT SAME STATE — the coexistent forces a bearing, pier cap or connection check needs, not each item's own envelope. If the governing load is an envelope (or an Add containing one), it is resolved recursively to a single deterministic state (a weighted sum of static/stage cases, pinning each envelope to the child that governs at the key item), re-read at that state, and gated against the value MIDAS itself reports; it refuses rather than approximates. Near-ties are reported. Items: items in set syntax — elements 12 or 15to20, nodes N12, general links L12, elastic links EL12 (a range keeps only ids that exist) — and/or structure groups. keyItem must be in the set. Values come back in the units asked for (default the model's); plate results are per unit length. Read-only (only /post/TABLE result reads). Call concurrent_forces_setup first for names and keyEffect ids. Runs as a job on the website.

Load Combination Contribution Analyzer, step 2. Splits one or more load combinations' results at a set of items into the load cases that produced them: for every item, output point (beam I/J and intermediate points, plate nodes and centre), component and max/min, the signed contribution of each case, its share of the gross, and the governing permutation written out with factors multiplied down (e.g. 1.35*Self weight(ST) + 1.5*LM1(MV:max)). Add superposes; an Envelope is resolved to the child that governs at each item (the governing child is counted per envelope); ABS gives |f·R| shares; SRSS energy shares. Moving-load, settlement and response-spectrum cases enter at their max or min end. Construction-stage cases are read at the final stage's last step. Cases are identified by type and name together. EVERY item is recomposed and must match the value CIVIL NX reports for the combination at the same item, part, component and sense — if any does not, the run stops and nothing is reported. Returns per combination: the cases ranked by share of the gross over the run, cases zero everywhere, envelope governing counts, and the critical item (largest |value|) per component and sense with its full breakdown; rows largest |value| first; csv: true stores every row. Tables: BEAM, TRUSS, PLATE (per unit length, local axes), ELASTICLINK, GENLINK, REACTION (supported nodes only — CIVIL NX answers other nodes with a made-up total; zero reaction rows it omits are read as zero), DISPLACEMENT. Items in set syntax (elements 101to148, nodes N1toN20, general links L5, elastic links EL7) and/or structure groups (for node tables: the group's nodes plus the nodes of its elements). Read-only (only /post/TABLE reads). Runs as a job on the website.

Structured reference for writing a CIVIL NX model through the API (civil_write_tables): the material standard names CIVIL NX knows (46 concrete standards), material fields per type, grades known to work, every user section shape with the order of its dimensions (vSIZE), catalogue section examples, plate thickness, beam / truss / plate element rows and plate STYPE codes, support constraint strings, load case / self weight / nodal load / combination rows, creep-shrinkage and strength-gain code options — each with its source: MIDAS IT's open-source midas-civil-python library (MIT), the MIDAS API manual, or behaviour measured on live CIVIL NX. Also every option list in midas-civil-python (148): the 67 static load case types, beam / pressure / plane load options, combination types, the 15 moving-load codes with their standard vehicles (Eurocode LM1–LM4 incl. UK NA SV/SOV, fatigue and rail; Indian road and rail), point springs and elastic links, temperature, tendons and prestress, construction stages, response spectrum / time history, units and result components. The grade lists inside each standard and the steel section catalogues are CIVIL NX's own and published nowhere: the answer says how to confirm one safely. Topics: overview, materials, sections (shape: one shape), thickness, elements, supports, loads, moving_loads, boundaries, temperature, tendons, construction, dynamic, units, results, time_dependent, python; search alone looks through every list and vehicle.

Creates nodes in the open CIVIL NX model from X, Y, Z coordinates with the Node Generator plugin's own engine: every check the plugin window makes (blank or non-numeric coordinates, bad or duplicate ids, ids above 999999, ids that already exist, coincident nodes within a tolerance), its numbering modes and its write rules. Give the points as nodes [{id?, x, y, z}] or as table (text pasted from Excel or a CSV; a header like ID,X,Y,Z is recognised, decimal commas and semicolon CSVs too). Coordinates are in inputUnit (m or mm) plus an optional origin offset, and are converted to the model's length unit. numbering: 'auto' continues after the highest existing node id; 'start' uses start + increment; 'column' keeps the ids given (default when every row has one). An id that already exists blocks the write unless overwrite: true, which MOVES those nodes (and the elements on them). Coincident nodes are reported first; choose coincident: 'skip' or 'create'. Previews unless apply: true with confirmPlanHash; new nodes go by POST (create-only, so a node made since the preview is never overwritten), overwrites by PUT, then db/NODE is read back. create_nodes_undo reverses it.

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.

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.

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).

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.

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.

Creates, changes or deletes rows in any CIVIL NX database table through the MIDAS API — nodes, elements, materials, sections, thicknesses, supports, links, load cases, loads, groups, stages, combinations, anything the API manual lists — so a model can be built from scratch or changed where no plugin tool does it. Look up the table and its fields first with midas_docs_search / midas_docs_read (e.g. "db/ELEM"), and read the current rows with civil_read_table. writes is a list of steps run in order: { table, op: create (POST — new keys only, refused if a key exists) | upsert (PUT — creates or changes; GRUP lists and CNLD/BMLD/PRES/RIGD items MERGE, they are never removed by a PUT) | delete (DESTRUCTIVE — needs allowDestructive; a node takes its elements, an element its loads, a load case its loads), rows: { "<key>": {fields} } | ids: [keys] }. The preview simulates every step over the current model: what each creates, changes (which fields) and deletes; it blocks keys that already exist on create, elements that refer to nodes, materials, sections or thicknesses that do not exist (CIVIL NX accepts a missing section silently), deletes and UNIT / MVCD writes without allowDestructive. Then apply: true with confirmPlanHash writes the steps (stopping at the first refusal), reads every touched row back and reports anything not stored as sent. civil_write_tables_undo puts every touched row back.

Designs the post- or pre-tensioning tendons of a concrete girder in the open model to EN 1992-1-1 with the Tendon Designer plugin's own engine, or reads the model's own tendons and checks them (mode improve, the default when tendons run along the girder). Reads the girder (a structure group, element list or the CIVIL NX selection; for improve it is picked from the tendons), its sections, supports and concrete, and the forces: construction-stage results when the model has stages (stage by stage for improve), else the static load cases named, plus an optional live envelope and ULS envelope combination. The girder is ONE girder line (a group holding several girders is split; girderLine picks one). Composite girders (precast + deck slab) are checked stage by stage (compositeMode) with the slab's own concrete, including the slab top; standard precast beams are pre-tensioned on their published strand positions, with debonded (sleeved) strands set or searched for by debonding, each end's length separately. Then auto-designs the layout (new) or reads the tendons in (improve), and runs every check: stresses at transfer and in service, Magnel, load balancing, losses, ULS bending, cover, spacing, bend radius, anchorage zones. autoResolve tries the smallest change that clears failed checks.

Start here for an EN 1992 section check. Reads one beam section of the open model through the shared MIDAS section library (any CIVIL NX section family; composite deck slabs as separate regions; tapered sections per end), places the bars from the given schedule with the Eurocode Section Checker's own placement and, for a prestressed beam, the tendons - and RETURNS A DRAWING of the section with every bar and tendon. Compare it with the user's drawing and correct rebar / psc.tendons until they match, then call ec2_section_check. Also returns depth, width, area, the bars placed per schedule row (or why a row failed), the concrete class read from the model material and the member type / length the model suggests. An unknown sectionId is answered with the model's beam sections. Read-only.

EN 1992-1-1 / EN 1992-2 check of concrete beam, column, pier and pile sections with the Eurocode Section Checker plugin's own engine. Reads the concurrent force sets at the chosen stations for the chosen combinations (BEAMFORCE for plain combinations; BEAMFORCEVBM for envelopes and moving loads, with the concurrency guard - a combination with no concurrent sets is checked at the corners of its force box, never mixed), then checks every row: ULS biaxial bending with axial force (fibre section), shear Vz and Vy (6.2), torsion (6.3), detailing; SLS stresses (7.2) and crack width (7.3) under characteristic / quasi-permanent rows; columns and piles to 5.8 (slenderness, imperfections, nominal curvature). Prestressed beams (psc): transfer stresses, stage-by-stage stresses with the girder alone and the composite section, ULS with the tendons' strain, shear with prestress, interface shear (6.2.5), decompression and crack width (Table 7.1N / 7.101N). Returns the verdict, the governing row of every check per section, the worst rows and what was not covered. Read-only; a job on the website.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idbe0c909db30defa5.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/be0c909db30defa5/claim.
Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
card completeness
100%
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
spec deviations
0
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
