Asked: a document manager like a paid PDM, without that price (#1058; again #1129: "shouldn't have to pay to manage my own files"). Built (vault-09 2026-11-06, in /lab; docs/0.9-sessions/vault-09.md): the Documents panel over a project folder in CadCraft (View > More > Documents..., or DOCUMENTS), PartCraft and BimCraft (File > Documents...), and so in SuperCad Studio, which hosts them. Check out and in with a lock file two people respect, revision letters (A.1, A.2, A, B.1; ASME skip), states (work in progress, for review, released, obsolete) with the revision table and a revision block on the sheet, history of who did what, where-used and BOM (PartCraft assemblies, xrefs, IFC links), approver list and four eyes (LC.8 merged), title-block fields VAULT.REV/STATE/DATE/APPROVER, read-only guard on Save, cloud folders in Studio (server built). Walkthrough: help topic "Documents and revisions (the vault)" in the three apps. Tested: lib/vault 141, UI 68, bridge 15, cloud 22, TWO REAL PROCESSES on one folder and on a cloud folder 86 (24 of 24 simultaneous check-outs, one winner each), walkthrough buttons 82; real pages 26+26+45 and Super 15; lock_ops.rs 4 under rustc. Found and fixed: BimCraft did not mount in Super. Not built: the sheet set's index does not show each sheet's revision; Open copy and Compare only in CadCraft; the approver is a typed name; no cloud folder in a web tab (Studio first); the commands in desktop-shell are not cargo-compiled (Windows Studio 0.9 build). Real shared-folder check with two people: SU.1058-HAND.

FeatureSU.1112 Link to SU.1112Comment on SU.1112 Live in every app: see each other's cursors and names while co-editing

Asked (#1112, Oct 28): collaboration where people see each other's cursors, so working in teams is easier. CadCraft's Live already shows other people's cursors and selections (live.js presence). Do: the same presence layer in the other apps' Live sessions (cursor, name colour, selection), reusing the CadCraft code through the shared Live library. Relates to DC.27 and EG.41. **Implementation started 2026-11-02** (0.9 pick #7, second five, hardest first; session `live-cursors-09`, log docs/0.9-sessions/live-cursors-09.md). Status moves to Partly built or Built only when the code is reachable and tested (rule 49). **Built 2026-11-02** (session `live-cursors-09`, log docs/0.9-sessions/live-cursors-09.md): one shared presence layer (assets/js/live-presence.js, synced by tools/shell/sync.mjs) with a thin adapter in each app's live.js; BimCraft, ModelCraft, TakeoffCraft, CivilCraft, DetailCraft and PartCraft now show cursors, names in the person's color and selections; CadCraft and MarkupCraft keep their own views on the same palette. Tested with two real pages per app (tools/live-apps-test/browser-apps.mjs) and test-presence.mjs.

Asked (#1192, Nov 3): add UK steel member sizes for UB, UC, PFC, EA, UEA, CHS, SHS, RHS. Built in /lab: 976 sizes from the Steel for Life Blue Book (hot finished and cold formed hollow sections apart) in the shared section table, in DetailCraft's profile lists, CadCraft's Standard panel, PartCraft weldments and BimCraft's rolled-shape check. Sizes typed as on drawings work (305x165x40 UB, L100x100x10). DetailCraft now handles unequal angles: both legs in IFC in and out and NC files, a mirror turns the piece end for end. Not checked yet by a UK fabricator; NC files for UEA not run on a machine.

FeatureSU.961 Link to SU.961Comment on SU.961 Sprockets for roller chain by standard (the missing third of #961)

Asked (#961, Oct 24, in Spanish): nesting of parts inside the CAD, standard profile tables as in AutoCAD Mechanical, and sprockets. Checked 2026-11-05: nesting is built and released (PartCraft's Nest flat parts, CadCraft's Nesting add-on; SU.755, NEST-CAD-PATH) and standard steel profiles are built (the shared section tables in CadCraft's Standard panel, PartCraft weldments, DetailCraft; UK sizes in /lab by SU.1192). Built 2026-11-06 (sprockets-data): sprockets are a CadCraft add-on, Roller chain sprockets (id chain, off by default, in the lab): SPROCKET draws the real tooth outline for a chain number and tooth count; CHAINS lists the table; CHAINSOURCES names the catalogues. Table lib/chain/chain-table.json: 38 chains (ANSI 25 to 240, ISO 606 A series 08A to 48A with 085, B series 04B to 48B), pitch, roller, inner width and plate height read from nine public catalogues on 2026-11-06 and kept only where two agree (tools/chain/chain-sources.mjs, build-chain-table.mjs); NOT copied from ISO 606 or ASME B29.1. Left out: ISO 04C, 06C, 36A (one catalogue only) and plate heights the catalogues dispute (null). Found by the real rows: the default tip circle let the swinging roller hit the tip edge at 25 to 28 teeth, now 0.35 p above the pitch circle. Tests: test-chain-table.mjs 3326/0 (every chain draws and seats at 9 to 80 teeth), test-chain.mjs 298/0, add-on test 14/0, browser-chain.mjs 11/0 in /lab/cadcraft, catalogue entry + listing seeded (lab). Limits: the tooth form (2 % seat clearance, 80 degree seat half angle, tip, tooth width) is our generator's, not the standard's, and no sprocket was compared with a catalogue sprocket; CadCraft only (PartCraft, ModelCraft and SuperCad Studio hosts and Library items on the owner's seed go are not done).

FeatureSU.810b Link to SU.810bComment on SU.810b A live link from a .3dm modeller into ModelCraft and PartCraft (one way, a script on the other side)

Asked (#810, Oct 19): a live connection between Rhino models and our apps, perhaps through Grasshopper. Built 2026-11-06, in /lab (log docs/0.9-sessions/3dm-link-09.md; design docs/spikes/SU.810.md). One script, cadcraft_link.py, runs in Rhino (watches the document, pushes after a pause, only what changed) and in a Grasshopper Script component (each solve). It sends .3dm bytes to Studio on this computer; link_push and link_status replace what the link brought last time: one group in ModelCraft (its placement, tag and neighbours stay; pushes within 2 s share an undo step), one import feature in PartCraft (features rebuild; a model that does not close changes nothing and says so). Over 4 MB goes in parts. The saved file keeps the link. Library lib/3dm-link, help live-3dm-link in both apps. Tests: tools/3dm-link/test.mjs 31/0; browser.mjs 38/0 (the real script with rhino3dm's writer, through the reference server and hub relay, into real /lab pages). Never run: real Rhino and real Grasshopper (none here; a stand-in plays their document and events, member names checked against McNeel's docs), Studio's native server, files saved by Rhino itself, SuperCad Studio's mounts. Not built: changes going back the other way, a packaged plug-in.

Discord (a Discord member, Oct 29): "CAMCraft", CAM + factory control + SCADA in the suite. Owner 2026-10-30: an add-on, not an app (eight apps). Pieces already in 0.8: CAM with editable posts in PartCraft (LC.15), send G-code to a machine on the network (EG.40, partly), the flow add-on for layout and simulation (SU.858), soft PLC with ladder / structured text (XE.13, partly), live data over OPC UA, MQTT, Modbus, BACnet (XE.9, IND.12, partly), plant historian (CH.27). The add-on ties them into one place: a machine and cell list (from the flow layout), a job queue that posts and sends programs to each machine, machine state read live (OPC UA, MQTT, MTConnect), an operator screen drawn over the layout with values, alarms and trends, history and simple OEE. Reading first; writing to a running machine or PLC stays off by default, behind a per-device switch and a confirm. Not a safety system and never in a safety chain — help says so.

FeatureFX.56 Link to FX.56Comment on FX.56 Auto-focus panel (Settings › Global) and split tool tiles

Owner 2026-11-05. (1) Auto-focus panel: one engine in the shell (window.ccAutoFocus in assets/js/app-settings.js, CSS in app-shell.css, strings in lang/shell): a panel with several sections opens one and closes the others, a lock beside the caret keeps a section open, remembered per panel; a menu command opens the section it works with; a Settings switch (cc-autofocus, default on) lets people choose how the apps work best. CivilCraft: the left panel (Landscape on) and the Properties panel (groups by heading). The other seven apps adopt it by registering their panels. (2) CivilCraft Landscape ribbon tiles that hold several tools (Grade, Hardscape, Areas, Levels, Irrigation) are split buttons: the icon runs the tool used last, the edge with the arrow opens the menu (civilcraft/a Discord member/split-menu.js); the same pattern is wanted in the other apps. Tested headless: panels, setting on/off, split clicks; Landscape 533/0. Added 2026-11-05: Hardscape, Areas and Levels have their own sections in the Landscape panel (tools + what is drawn); the toolbox (layouts with a tool list) joins the auto-focus panel: its groups close each other, and the toolbox group and the panel section follow each other (shell: ccAutoFocus mode details, app-workspace.js tbxAf; civil link in landscape-ui.js). 2026-11-05 all eight apps: window.ccAutoFocus.auto() folds every app side panel with two or more sections (a section heading or its *-sec-head bar; MarkupCraft details sections; toolbox groups in the toolbox layouts), no per-app code; Settings › Global › Auto-focus panels switches it off. Split tool tiles stay CivilCraft-only until the other apps ask. Command links 2026-11-05: a tool that works with a panel section opens it (app-settings.js LINKS table, one line per rule): CadCraft constraint and parameter commands to Parameters; TakeoffCraft measuring tools to Items and note/cloud/highlight to Markups; ModelCraft Paint to Colors. The other apps have no tool with a section of its own yet; add a rule when one does.

Education (Track ED) 2
FeatureED.1 Link to ED.1Comment on ED.1 Live TeamWork: follow the teacher (follow the presenter)

Owner 2026-11-03 (educator kit): "allow students to follow the teacher". Built in a Live TeamWork session (assets/js/live-follow.js, shared by every app that uses the live presence layer; CadCraft and MarkupCraft mount it from their own live UI). A person can choose Follow on another person's name and their view moves with the presenter's: 2D camera centre and zoom (a smaller window zooms out to show all of the leader's view), 3D eye, target, field of view and parallel height, and the sheet, storey or space when the app can open it. The host can press "Ask everyone to follow me"; each joiner can still step away. Following stops by itself when the follower pans, zooms or orbits on their own, and a chip names who they were following and offers to rejoin. The view travels in the existing presence message, newest only, and nothing about it is saved in the file. Not tried in a live session with real students; the educator kit copy can now mention it.

FeatureED.2 Link to ED.2Comment on ED.2 Live TeamWork: class view, the teacher looks in on each student's work

Owner 2026-11-03 (educator kit): "allow instructor to look at student progress". Built as the people list in Live TeamWork (same module, assets/js/live-follow.js): everyone in the session with their colour and name, the tool they are running, the sheet they are on, how many edits this window saw from them and when the last one was, and a Follow button on each, so the teacher can go to a student's view. Names from other people reach the page as text only. NOT built from the first plan: students each working in their own drawing inside a class room, a live thumbnail of each student's work, and "Look in" read-only or "Help" with a separate viewer role. Today the class works in one shared drawing and the teacher sees the class at a glance in the list. Not tried in a live session with real students.

Library 8
FeatureLIB.C1 Link to LIB.C1Comment on LIB.C1 Library collections: the Library is the one home of every object; each app starts from a default collection

Owner 2026-11-05: library as the primary source of all object information; CivilCraft gets a default collection from the Library (its plants and items), usable in every app. Spec docs/0.9-LIBRARY-COLLECTIONS.md. Built: collections tables (migration 124), LibraryCollections, GET /api/v1/library/collections[/<slug>|/app/<app>], bin/library-collection-make.php, test bin/test-library-collections.php (17/0). Next: publish the 421 seed plants (bin/library-import-plants.php, dry run clean), make civilcraft-landscape the CivilCraft default, then CivilCraft Landscape loads it (C.3), places any Library item (C.4), other apps add it (C.5). Parametric Library objects (params + generator) are a separate track. C.2 done 2026-11-05: 421 seed plants published as Library plant items (system author), collection civilcraft-landscape published and set as CivilCraft default; served at /api/v1/library/collections/app/civilcraft. C.3 started 2026-11-05 (in /lab): the Plants section says where its list came from (the civilcraft-landscape collection, count, revision, or the built-in list when the Library is unreachable); Landscape panel sections fold shut and a menu command opens the one it works with (landscape/fold.js). The app still reads plants.csv for the data; reading the collection manifest itself comes next. C.3 done 2026-11-05 (in /lab): CivilCraft Landscape now reads its plants from its default collection (GET /api/v1/library/collections/app/civilcraft/plants.csv; every published plant when no collection is set; the built-in list when the Library cannot be reached). Panel sections: opening one shuts the others unless locked (lock icon by the caret). Landscape tests 533/0, collections 17/0. C.4 (place any Library item) and C.5 (other apps) still planned.

FeatureSU.747c Link to SU.747cComment on SU.747c NURBS surfaces, step S3: fillets and blends between faces, thickening, a solid written to STEP as one closed shell

Asked (#747, #748, #749, #750, Oct 16): concept-to-prototype NURBS and production-quality surfacing. S1 (curves, untrimmed surfaces, measured G0 to G2) is Built in 0.8; trimmed surfaces, solids from them with union, subtract and intersect, and PartCraft Bake are Built in /lab 0.9 (docs/0.9-sessions/nurbs-09.md). That log lists what is left and says 'Fillets between faces come next'. Plan (lib/nurbs): (1) fillets and blends between two faces, constant then variable radius, deviation from the rolling ball measured; (2) thickening a surface into a solid, self-intersection refused and named; (3) a solid written to STEP as one closed shell, read back; (4) Booleans as nodes. Each result measured against a closed form. Not claimed: class-A surfacing, the other programs' file formats, a result equal to Alias or ICEM Surf. Class-A and equality with Alias/ICEM are never claimed. Completed 2026-11-06: in /lab (ModelCraft, PartCraft, SuperCad Studio's panel through the shared libs): fillet between two faces (constant/variable radius, convex/concave, closed edge; deviation from the rolling ball measured), several edges at once (mitred corners; one sphere patch where three flat square faces meet, radius equal), thicken into a solid, STEP and IGES (186 over closed shell 514) with a solid as one closed shell, read back as a solid, Booleans as nodes in the node editor, help lines. Measured against closed forms (removed volume within 2 % at tol 0.05, goes with the tolerance). Not built: vertex blend for curved faces or unequal radii, fillet between faces that do not meet, inside fillet ending on a slanted or curved face, several inside edges that reliably close (the result line says if not), Booleans/fillets on the surfaces without triangles, IGES not tried in another program. Tests: docs/0.9-sessions/nurbs-s3-09.md.

Asked (#749, Oct 16): managing large, complex assemblies, with Catia named as the reference. PartCraft's stress tests so far are 750 features in one part (D7.51) and closed-loop mates (D7.40); no row measures an assembly of thousands of parts. Do: (1) generate the test assemblies ONCE under testfiles/generated/ (registry testfiles/LARGE-FILES.md, memory 'large-test-files'), from repeated instances of a few parts, not from files typed by hand; (2) measure open, rotate, select, mate-solve and save at each size in the real page, one browser test at a time with nice and timeout; (3) fix what the numbers show, in this order of likelihood: instancing (one mesh, many transforms), level of detail and a lightweight display mode, hiding by visibility sets, mate solving only for what moved, saving without rewriting unchanged parts. Record every before and after number in the log and in the release notes (memory 'test-results-in-release-notes'). Not claimed: Catia's feature set, any size without a measurement. Untested: everything, including the sizes above. assembly-09 2026-11-06: Measured at 1,000, 5,000 and 20,000 copies of three small parts in the real page (headless Chromium on a CPU renderer, never a GPU), before and after; fixed: one draw group per part (40,000 draw calls to 3 at 20,000), a joint turned places only the parts behind it (5.0 s to 65 ms at 20,000), the part list shows its first rows (a click 11 s to 26 ms), boxes while the view moves (Views > Lightweight display keeps them on; a frame 15.7 s to 0.9 s on the CPU renderer), and assemblies open up to 50,000 copies (500 before). A frame in full detail is not faster on the CPU renderer; assemblies of heavy parts and a real GPU are not measured. No claim about any other program. Table and tests: docs/0.9-sessions/assembly-09.md.

Asked (#908: Abaqus, Ansys, SAP2000, STAAD.Pro, ETABS and others; #890 RFEM; #1057 SPACE GASS; #1141 SAP2000): finite elements beyond beams. Built (lib/fem, own code, Apache-2.0): four-node shell (MITC4 or DKQ), ten-node tetrahedron, modal analysis, sparse IC(0)-PCG solver, slabs and shear walls through the frame mesher; known-answer tests with cited derivations (Navier, Lame, Timoshenko, Leissa, Blevins; 60 + 10 + 15 checks). Reachable: the Analysis panel of BimCraft and DetailCraft, block 'Finite elements: natural frequencies': modes, period, effective modal mass, mode drawn on the model, member end releases and rigid floors carried, settings saved with the model, the report carries the table, help written. Deflections, reactions and plate moments of slabs and walls are shown by the frame solver in the same panel (lib/frame plates; lib/fem agrees with it to 1 % in tests). Solid FEM: lib/fem's tet10 solid is the PartCraft add-on 'Solid FEM' with its own panel (SU.908c); PartCraft keeps its own solver (owner 2026-11-06). DKQ is a panel choice; the static solve in the panel stays lib/frame's (one engine, no second copy). Not built: nonlinear, contact, damping, response spectrum, soil models. No claim of equality with any other program.

FeatureTKW.1 Link to TKW.1Comment on TKW.1 Weight and temperature units (kg, lb, t, ton; °C, °F, K, °R)

Asked in support message #1329 (metric in the quick properties, kilograms, Celsius). Owner 2026-11-08: build weight and temperatures, both F and C, into 0.9. Shared table lib/units gets two kinds: mass (mg, g, kg, tonne, oz, lb, ton, long ton; exact factors from the 1959 pound) and temperature (K, °C, °F, °R; offset scales, converted without a detour through kelvin for C and F, negative values read correctly); Settings › Global › Units lists them (en, es-MX, id words). TakeoffCraft: lb, ton, kg and t as typed-quantity units (priced like CY), an optional Temperature on every item typed and shown in °C or °F (Settings › TakeoffCraft: Follow Global / °C / °F), kept in kelvin. bin/test-units.mjs 261/0, bin/test-takeoffcraft.mjs 1210/0. Seen in the real /lab page: browser-weights-temps.mjs 12/12 (unit lists, temperature typed in C and F, display setting, undo). Temperatures are absolute (a difference is not converted). Reports/exports do not carry the item temperature yet. Reply sent 2026-11-08 (support #1329, answered).

Resin printing add-ons (RSN) 9
FeatureRSN.1 Link to RSN.1Comment on RSN.1 Resin slicer core: layers at the printer screen, hollowing, island check, layer preview (add-on slicer-resin)

Built in the lab: add-on slicer-resin over lib/printresin, in the 3D Print card under "Printing with: Resin". Layer pictures at the printer's screen resolution with smooth edges, hollowing with vent holes, floating pieces ringed on the layer preview, time, resin and cost. Free, nothing locked. Printer sizes are the makers' published numbers and the exposure numbers are starting points. Tests: slice 35/0, browser 24/0. Never run on a printer.

FeatureRSN.2 Link to RSN.2Comment on RSN.2 Resin file: Elegoo GOO (add-on printer-resin-goo)

Built in the lab, from Elegoo's published Goo Format Spec V1.2 with no third-party source read. What the spec leaves open is now switchable on the card: byte order (big or little endian; big by default from an unverified secondary report) and checksum (negated sum or plain sum). The spec's own example offset cannot be reached by its field table (the table gives 195,477 bytes, the example 195,255), so the example is read as illustrative. Other gaps are marked SPEC-GAP in rs-goo.js. Read back by our own reader only (86/0). A real Elegoo printer is the check.

FeatureRSN.3 Link to RSN.3Comment on RSN.3 Resin file: SL1 layered-image archive (add-on printer-resin-sl1)

Built in the lab, from public descriptions (Prusa publishes no specification): config.ini and numbered 8-bit PNG layers in a zip. Several keys are marked UNVERIFIED in rs-sl1.js. Read back by our own reader only (38/0). NanoDLP's different layout is not built.

Built in the lab: a 46 x 30 mm test part (square pillars 0.3 to 1.5 mm, round holes 0.4 to 1.5 mm, two bridges) and the same print at five exposures from 70 to 130 percent, one file each, in a zip. Test 10/0 and in the browser test.

FeatureRSN.5 Link to RSN.5Comment on RSN.5 Resin supports and raft: pillars from islands, overhangs and the first layer

Built in the lab inside slicer-resin: the part is lifted on a raft; unsupported areas are sampled on a grid and each gets a pillar to the raft or the part below, fine tip and wider shaft; density light, medium, heavy. New and unproven: pillars do not brace each other, no suction-cup detection. Tests in test-slice.mjs.

FeatureRSN.6 Link to RSN.6Comment on RSN.6 Resin files from Chitubox: CBDDLP and CTB (add-on printer-resin-chitu)

Built in the lab (owner 2026-11-08), clean room: both written from ONE prose document (cbiffle/catibo a Discord member/cbddlp-ctb.adoc, BSD-2-Clause repository; whether that file carries its own licence is for legal to confirm), no GPL code read. CBDDLP in full; CTB for the layout that document describes (version 2, 7-bit pixels), with the document's cipher as an option. Options on the card: edge smoothing levels, projection flag, resolution field type, encryption. The document says it was tested on the Creality LD-002R and files for the older Elegoo Mars; no other printer is named. Later CTB versions are NOT written (see RSN.10). Tests cbddlp 28/0, ctb 25/0, browser 31/0. Never loaded on a printer.

FeatureRSN.8 Link to RSN.8Comment on RSN.8 Resin slicing on a worker thread

Built in the lab (2026-11-08). The resin slicer runs on a module worker (lib/printresin/rs-worker.js, started by rs-run.js) so the page stays alive while a big plate is sliced; the worker borrows the print stage's manifold file and ps-slice.js through the URLs the host already gives the filament slicer. The layers come back as run-length data, moved not copied. Cancel ends the worker. A page that cannot start a worker slices on the page as before. Same layers byte for byte as slicing directly (test-worker 14/0; the real-browser run confirms rs-worker.js starts). With FX.140 the drawing is also about 6 times faster. Not tried on a real printer.

FeatureRSN.10 Link to RSN.10Comment on RSN.10 Resin files: Chitubox CTB versions 3, 4 and 5 (in add-on printer-resin-chitu)

Built in the lab (owner 2026-11-08: "build to version 3+"), our own Apache-2.0 code from a written specification (docs/resin-formats/ctb-v3-v5-SPEC.md), by a builder who saw nothing else. Two layouts under one name: plain tables (version 3, 4, 5) and encrypted settings (version 4, 5; AES and SHA-256 through the platform's WebCrypto). Options on the card: layout, version, edge smoothing, projection, layer scrambling. The vendor's disclaimer text is not reproduced (our own 320 bytes: a printer might check it). Which printer needs which layout is not established. The v2 writer's cipher constant is now an option too. Tests ctb3 170/0, incl. the spec's test vectors. Never loaded on a printer.

FeatureRSN.11 Link to RSN.11Comment on RSN.11 Resin files: Anycubic Photon Workshop PWMX and PWS (add-on printer-resin-anycubic)

Built in the lab (owner 2026-11-08), our own Apache-2.0 code from a written specification (docs/resin-formats/anycubic-pwmx-SPEC.md), by a builder who saw nothing else. .pwmx (file version 1, optionally 516) and .pws. Options: mirror the picture, file version, edge smoothing, per-layer flag. Not written: versions 517 and 518 (the newer M5 and M7 families). The spec writer measured two public sample files (a .pws and a .pwmx) and found the real files differ from the reference code in three places; the spec records them. Tests pwmx 91/0, browser 38/0. Never loaded on a printer.

Layouts 1
FeatureRH.1 Link to RH.1Comment on RH.1 Rhino layout, Rhino keys and four views (Top, Perspective, Front, Right)

A built-in layout called Rhino (Settings › Global › Layout) and, as a separate setting, a Rhino key set (Settings › <App> › Menus, keys and mouse), for people who model with curves, surfaces and solids from a command line. Asked on Discord by a first-time visitor: the top, right, front and perspective views as an option, plus Rhino shortcuts. Layout (all eight apps): menus File Edit View Curve Surface Solid Mesh Dimension Transform Tools Analyze Render Panels Help (menubar set=rhino, each command under one menu; the verb decides for mixed groups), tool rows, two columns of tools left, panel right, command line in the status strip. New block `viewports` (layout four), filled only by apps that offer it: ModelCraft shows Top, Perspective, Front and Right at once (viewports-mc.js). One view is active and is the real view (picking, tools, keys unchanged); a click activates another; Zoom extents refits all; Ctrl+M maximizes and restores; leaving the layout gives the single view back. Keys (ModelCraft style `rhino`): typed Rhino command names (Line, Box, Extrude, Move, BooleanUnion, Top, Undo, 4View…) run the closest ModelCraft command; Ctrl+G, Ctrl+Shift+G, Ctrl+H, Ctrl+Alt+H, F9, Ctrl+Shift+E, Ctrl+M; right button turns the view, Shift+right pans. The layout's command line tries these words first (ccInput.typed). Not built: Rhino keys and four views in the other seven apps; Enter to repeat; osnap bar; per-view cameras are not saved in the file; other views draw no axes, guides or selection. Ctrl+H, Ctrl+Alt+H and F9 are from memory of Rhino's defaults: a daily user should check. Test: node bin/test-rhino-layout.mjs.
