auto_structure_groupsCreates 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 charac…
auto_structure_groups_undoReverses an auto_structure_groups run from the ledger: deletes the groups it created and puts every group it added members to back exactly as it was (from the snapshot taken just before the write). Refuses while a construction stage uses one of those groups, because deleting a g…
b2p_surveyReads 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, th…
b2p_convertConverts 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…
b2p_undoUndoes 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 th…
bridge_reshape_readReads 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; a…
bridge_reshapeChanges 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 poin…
bridge_reshape_undoUndoes 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 a…
bridge_thermal_calcCalculates 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 profil…
bridge_thermal_readReads 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-dept…
bridge_thermal_applyCalculates the temperature actions for the deck and writes them with the Bridge Thermal Loads plugin's writer: EC1T_Uniform_Exp/_Con (type T, element or system temperature), EC1T_Diff_Heat/_Cool (type TPG: beam section temperature bands, or a linear gradient for Approach 1 and p…
bridge_thermal_undoUndoes the latest bridge_thermal_apply or bridge_thermal_remove run (or the run named): deletes the EC1T_ cases present now and puts back the EC1T_ cases and loads saved before that run, merged into each element's current loads so other cases are kept. Refused in a different mod…
bridge_thermal_removeRemoves 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_und…
concurrent_forces_setupConcurrent 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…
concurrent_forcesConcurrent 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 resul…
concurrent_forces_probeConcurrent 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 m…

cs_stage_reportMakes the Construction Stage Reporter plugin's own reports of the open model's construction stages and returns download links (never the file inline): the Excel workbook (summary, stage matrices for structure/boundary/load groups, group tables, stage details, composite sections,…
culvert_previewValidates a 2D Culvert project with the plugin's own Eurocode core and returns what it would build: nodes, elements, soil springs, basic load cases (traffic unit cases), the EN 1990 Annex A2 combination counts (ULS, SLS characteristic, quasi-permanent) and the nested CIVIL NX co…
culvert_buildWrites the 2D Culvert model exactly as the plugin's Build: units, user material, sections, frame, soil springs, supports, every basic load case with its loads, and the nested EN 1990 Annex A2 combinations; then reads the loads back and fails if CIVIL NX dropped any. Into the ope…
culvert_build_undoDeletes every row a culvert_build wrote (combinations, loads, load cases, springs, supports, groups, elements, nodes, sections, material) from the ledger's record, and puts back the model's units. A model replaced by newDocument cannot be brought back. Previews unless apply: tru…

dxf_importImports 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 cre…
dxf_import_undoRemoves what one dxf_import created, with the plugin's own removal rules: it refuses unless the import's master group is in the open model; deletes the import's elements, then its nodes, only where they still match the fingerprint taken before writing (anything edited since is k…
ec_combinations_readReads the open model the way the Eurocode Load Combinations plugin does: every static, moving (characteristic/frequent pairs), construction-stage, settlement and response-spectrum case with the action and subtype the plugin proposes, the detected bridge type, the default scope a…

ec_wind_removeRemoves what the Wind Load Calculator plugin writes: every EC1W_ and C454W_ load case, its load group, and their beam/pressure/nodal loads — whether this tool or the plugin window wrote them. Loads anyone else put on the same elements are kept. Previews unless apply: true.
skew_grillageGenerates 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,…

pd6694_ssi_planRead-only: changes nothing in the model. Call it before pd6694_ssi_run, with the same inputs, to check that the PD 6694-1 Annex A soil-structure interaction run can go ahead — it uses the plugin's own planner. Needs abutments[].group (the wall plates' structure group) and ssi.de…
pd6694_ssi_runRuns the PD 6694-1 Annex A iteration with the plugin's own runner: Winkler springs on the walls (multi-linear), repeated analyses until the wall displacements settle, then the two design pressure cases written and the analysis set-up removed — keeping a backup of the model's own…
pd6694_ssi_removeRemoves everything an SSI run left (design pressure cases, spring groups, analysis cases) and restores the model's own springs from the run's backup (the plugin's Remove SSI). Previews unless apply: true.
point_to_patch_dispersalThe Point to Patch Convertor's dispersal for one point load: the code's contact area (or the load-derived one), the spread through surfacing and slab to the mid-plane or neutral axis, the effective patch b_eff × l_eff and its pressure, with the clause. Presets cover EN 1991-2 LM…
point_to_patch_readReads the open model as the Point to Patch Convertor does: whether the deck is plates or a grillage, its levels and groups, the point loads (nodal and beam concentrated) per load case that could be dispersed, any PATCH_ cases already written, and every preset with what it still…
point_to_patch_applyConverts 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 rul…

civil_loads_supportsThe 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 t…
civil_combinations_quickWrites general load combinations from plain factors, e.g. { name: "ULS1", factors: { "SW": 1.35, "SDL": 1.35, "LM1": 1.5 } } — for hand-picked combinations; for the full code set use ec_combinations_apply / cs454_combinations_apply. Each name is looked up: static load cases (ST)…
civil_remove_loadsTakes loads out of the model without touching other load cases: CIVIL NX keeps every case's beam loads, nodal loads, pressures and temperatures of an element or node in ONE row, so a plain delete would take the other cases with it — this tool rewrites each row with the items tha…
