* Native file pickers, background opening, drag and drop and recent files Open (models, SolidCraft designs and tagged meshes in one picker), Save, Save As, Write Deck and Recover go through the host's file pickers (rfd in the desktop app, injected as Services so the UI crate stays portable and tests answer them). Files open on a copy of the session in a worker thread and replace it only on success; files dropped on the window or named on the command line open the same way. A recent-files list, an unsaved-changes prompt, Cmd/Ctrl+O/S/Shift+S. Programmatic calls never open a picker: ui.start opens the form.

Help > Samples, the empty viewport's start screen and the Tools > Samples entry open them (asking first over unsaved changes); Solve runs in the background like a file opening and the Results tab comes up. --sample [parts|cantilever|impact] on the command line. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * The Craft-family shell: title bar, workspace ribbon, browser, context panel, timeline The window now follows SolidCraft's and VectorCraft's layout and themes: - title bar with the mark, quick actions (File menu, save, undo, redo, Solve, search, theme, help), the model's document tab and the version; integrated under the macOS traffic lights, own caption buttons and resize zones elsewhere (titlebar.rs); - workspaces (Prepare, Model, Analysis, Results) with their tabs, and panels of icon buttons whose labelled drop-downs list the whole catalogue, coming-soon entries greyed with their milestone; panels collapse, then go into a » menu, when narrow; - the browser: geometry and mesh with eye toggles, definitions with counts, results; - no permanent Commands list: command search (S, Cmd/Ctrl+K) and a command line; - the context panel on the right only with context: the command form, results controls, the selected definition's properties with Edit and Delete; - navigation bar and orientation gizmo in the viewport; the journal timeline at the bottom with undo positions; - SolidCraft's light and dark tokens; craft-ui (IconButton, Tab, WidgetPalette). Menus and the search are view state (ui.set {menu, palette}), so captures show them. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Shell polish, docs and licences Menus painted as the family's (flat File menu with recent files, decks and samples), the legend sized to its text, two-line panel labels inside the ribbon, glyphs the UI font has, offscreen captures without fade-in, ui.start runs in-window file actions (samples, recover, solve) but never a native picker, ui.select. Control protocol, architecture, ROADMAP, AGENTS and ATTRIBUTION updated; THIRD-PARTY-LICENSES.txt with craft-ui and rfd. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Title bar mark from the application icon; fluid steps and domains in the shell The title bar draws the app icon's bracket (assets/app-icon/icon-small.svg's faces) as SolidCraft draws its mark; the window keeps its title-bar flags after the rebase. solve.run solves fluid steps too (solve.fluid); the browser lists fluid domains. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Simplify: cached per-frame data, one command per timeline roll, workspace setters - Icon textures are kept per pixel size (the shell draws several sizes a frame; the cache used to clear on every size change and rasterise again). - Opening a model or recovering one starts from an empty session instead of copying the current one; the replaced session is freed off the window thread. - Element counts, timeline items, search results and the selected definition's properties are cached until what they show changes; timeline tooltips are built on hover; long lists in properties are summarised. - edit.undo and edit.redo take a count: a timeline click is one command. - solve.run dispatches on the step's procedure (no string round trip) and reports its name. - The workspace and tab change together through UiState::select_tab/select_workspace (ui.set {workspace} alone now sticks); no per-frame syncing. - One busy guard, Kind::verbs, a fit flag for background jobs, ModelApp::home_view, the title bar's actions as an enum, dead code removed. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Title bar: Solve and tools at the right end; no traffic-light inset in full screen The owner's feedback on the title bar: Solve, search, theme and help sit at its right end before the version; on macOS the left group (mark, name, quick actions) moves into the traffic lights' room in full screen, where there are none, and back when leaving it. The layout is a pure function (bar_layout) tested for both states, narrow windows and custom caption buttons. ui.fullscreen {on} for agents. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Caps labels in Inter SemiBold egui has no bold weight of its default font, so the ribbon's tabs and panel labels, the workspace switcher and its menu, menu headings, the browser header, the context panel's headers and the Solve label were thin, especially in the light theme. They now use a label font family: Inter SemiBold 4.1 (SIL OFL 1.1, unmodified, fonts/OFL.txt, ATTRIBUTION.md), with egui's fonts as fallback, installed with the theme on the live and offscreen contexts. theme::label_font falls back to the default font until the family is bound (fonts take effect from the next pass), so nothing can panic. Panels widen to their label's longest word.

ModelCraft
An open-source, clean-room CAE modeling application in pure Rust: geometry to analysis-ready finite element models, with robust tetrahedral and hexahedral meshing, solver decks for Abaqus, Nastran and LS-DYNA, and its own linear static and modal solver. Desktop, browser and AI agents drive the same commands.
Status: early. The workspace, quality gates, the FE model, the command engine and the geometry boundary (SolidCraft's kernel and tessellator) are in place; meshing is next. See ROADMAP.md.
Build
cargo xtask ci # fmt, assets, licences, layers, clippy, tests, wasm
cargo xtask test --heavy # the heavy (ignored) tests and the doc tests
cargo run -p modelcraft-cli -- commands # every command and its parameters
cargo run -p modelcraft-cli -- run script.json # run a command script
Rust 1.95 or later, with the wasm32-unknown-unknown target for cargo xtask ci.
