GOAL: Produce a CONCRETE roadmap to FULL FreeCAD desktop feature parity for the FreeCAD->WebAssembly port. Be evidence-based: grep/read the actual sources, don't reason from general FreeCAD knowledge alone. Cite file paths. CURRENT STATE (verified working in the browser build): - FreeCAD 26.3.0dev compiled to wasm. Toolchain: emscripten 4.0.12, ASYNCIFY, JS-exceptions, **single-thread (NO pthreads, QT_FEATURE_thread=-1)**, static CPython 3.14, static Qt 6.11.1 (asyncify), static OCCT, static Coin3D. **NO dlopen** — every C-extension is registered via PyImport_AppendInittab in generated src/Main/WasmInittab*.cpp. **NO subprocess/QProcess, NO threads, NO native OS dialogs.** Browser file I/O via upload/download (deploy/index.html). FreeCAD.wasm ~243MB. - 3D viewport RENDERS (offscreen FBO + QPainter blit; Coin3D/OpenGL via WebGL). - **PySide6 FULLY WORKS**: QtCore+QtGui+QtWidgets bindings + shiboken runtime + signals/slots; `from PySide import QtGui` compat shim works; `Gui.getMainWindow()` returns a real PySide6 QMainWindow (shiboken wrapInstance); Python macro scripting drives geometry + GUI. - Workbenches LIVE (7): Part, PartDesign, Sketcher, Surface, Spreadsheet, Material (+None/Start). Measure + Import modules built-in. - Built-in C-extensions (inittab): Import, ImportGui, Materials, MatGui, Measure, MeasureGui, Part, PartGui, PartDesign, PartDesignGui, Sketcher, SketcherGui, Spreadsheet, SpreadsheetGui, StartGui, Surface, SurfaceGui. - MISSING modules (present in src/Mod but NOT built/registered): Draft, BIM, CAM, Fem, Mesh, MeshPart, Points, TechDraw, Assembly, Plot, Show, OpenSCAD, Web, Inspection, ReverseEngineering, Robot, JtReader, Help, AddonManager, Test, Tux, TemplatePyMod. PATHS: - FreeCAD source: /home/magik6k/lcad-wasm/freecad-port/FreeCAD (src/Mod/<WB>, src/Gui, src/App). Each module has CMakeLists.txt, App/ (C++), Gui/ (C++), and often a Python workbench tree (Init.py/InitGui.py + *.py). - wasm build tree: /opt/toolchains/src/freecad-gui-build (CMakeCache.txt, build.ninja, src/Main/WasmInittab*.cpp). - deploy: /home/magik6k/lcad-wasm/freecad-port/deploy (index.html = browser file I/O + boot; *.data = packaged FS). - The module-enablement pipeline already used for the live modules: add C-ext to inittab (RegName=CInitSuffix form via FREECAD_WASM_EXTRA_PY_MODULES + the SHARED->STATIC rewrite in FreeCAD/CMakeLists.txt:91-107), package the module's Python tree onto the wasm FS via file_packager (freecad-mods.data), drop unbuildable OCCT deps, fix dependency gates. - External-tool deps that are a problem in wasm: Fem (calculix/gmsh solvers via subprocess), BIM (ifcopenshell, needs building for wasm + network for downloads), CAM (post-processors), AddonManager (git/network), OpenSCAD (external openscad binary), Web (QtWebEngine — almost certainly not portable). For each thing you assess, classify wasm-viability: WORKS (already), EASY (module-enable pipeline, no hard blocker), MEDIUM (needs a dep built for wasm or a moderate workaround), HARD (needs a wasm-native re-architecture e.g. web worker/fetch/browser API), BLOCKED (fundamentally not portable — say why + what a degraded fallback looks like). Give a rough effort (S/M/L/XL) and cite evidence (CMakeLists deps, Init.py imports, subprocess/QProcess/network usage grep). DIMENSION 5 — Cross-cutting desktop GUI features (beyond workbenches). Assess current wasm state (grep src/Gui) of: undo/redo, cut/copy/paste + clipboard (QClipboard in wasm), drag & drop, the model tree view, property editor, selection view, Python console + report/output view, macro recording & playback (src/Gui/Macro*), the 3D navigation (mouse styles, navigation cube, view cube), measurement/section tools, printing & PDF/PNG export of views, units & preferences dialogs, dark theme/stylesheets, translations/i18n (Qt .qm loading), status bar, dock widgets/layout persistence, keyboard shortcuts. For each say WORKS/PARTIAL/BROKEN in wasm and what's needed. Reference that the 3D viewport already renders. Identify the ones most important for a credible desktop-parity feel.

Now I'm diving into the FreeCAD source code to examine the desktop GUI features and determine whether they're feasible to port to WebAssembly. Let me start searching through the GUI directory to gather concrete evidence about what's actually being used.

I need to dig into the WebAssembly build configuration—specifically what Qt modules are available, whether PrintSupport is included, and what the emscripten platform supports.

Most of these are core GUI features that compile into the main FreeCADGui library, which already works in wasm since the interface renders. The real question is what might break at runtime—clipboard support depends on emscripten's QClipboard implementation, printing needs QtPrintSupport availability, translations rely on loading .qm files from the filesystem, dock persistence uses QSettings which works but storage location is unclear, and the navigation cube should function since the viewport already renders. I'm checking what might actually be problematic in the wasm environment.

I'm checking the Qt WebAssembly implementation details—the build has clipboard, drag-and-drop, settings, translation, and print features compiled in at the Qt level, but the emscripten platform plugin behaves differently at runtime. Let me look into how Qt WASM handles clipboard through the browser's Clipboard API and what the print behavior actually does.

For printing, Qt WASM doesn't support native printer dialogs, but QPrinter can export to PDF which gets written to the in-memory filesystem and can be downloaded. Drag-and-drop works internally within the canvas but has limited support for OS-level interactions. Translations require .qm files on the filesystem, which aren't currently pack  …

I'm discovering that FreeCAD actually does use QClipboard for copying and pasting document objects through a custom MIME type, which means the copy/paste mechanism relies on Qt's clipboard system. On Qt WASM, this custom MIME data gets stored in Qt's internal clipboard rather than the system clipboard, so intra-application copy/paste still works since Qt maintains a local copy. However, cross-application clipboard operations appear to be where the limitations emerge.

I'm also noticing a critical gap: there's no IDBFS persistence set up, so FREECAD_HOME points to a temporary MEMFS path that doesn't survive browser reloads. This means user preferences, dock layouts, and QSettings don't persis  …

So the filesystem is entirely in-memory with no persistence layer — that means all user preferences, dock layouts, macros, and recent files get wiped on every page reload. This is a major gap for achieving desktop parity. I'm looking at where FreeCAD normally stores these settings, which is in the user.cfg file under FREECAD_HOME, and how Qt's WASM implementation handles QSettings...

FreeCAD actually uses its own ParameterManager with XML-based user.cfg rather than relying on QSettings for most preferences, though the dock layout persistence does go through QSettings in the MainWindow. Qt6 WASM automatically backs QSettings with IndexedDB for local storage, so that mechanism should theoreti  …

The NaviCube renders through OpenGL as part of the viewer's decoration layer, and since the viewport already uses an offscreen framebuffer with QPainter blitting, the NaviCube integrates seamlessly into the same scene. For window settings, Qt uses QSettings with vendor and application names, which on Qt WASM maps to the browser's localStorage for persistence.

There's a complication though: Qt WASM mounts IndexedDB-backed storage at the standard config path, so QSettings can persist window layouts, but FreeCAD sets FREECAD_HOME to /freecad/ which is in-memory storage. This creates a mismatch where window settings might persist through Qt's mechanism while FreeCAD's own configuration doesn't.  …

I found that .qm translation files are being compiled into a qrc resource file, so if the Translator loads them from the embedded resources rather than the filesystem, internationalization should work without needing to package files separately. I need to verify this by checking how Translator.cpp accesses the translations. On the other hand, GraphvizView relies on QProcess to execute the `dot` command for the dependency graph feature, which won't work in WebAssembly since subprocess execution isn't available—Graphviz would need to be compiled to wasm to make that feature functional.

I'm also noticing that Assistant.cpp uses QProcess for Qt Assistant integration, which is similarly blocked   …

The translations are embedded in the WASM binary through the qrc resource system, so i18n is working properly—language switching functions as expected. Now I'm gathering enough information to assess Dimension 5 and identify the gaps, then I need to verify how the save image functionality works since it writes to the filesystem and requires a download step.

In WASM, file writes go to MEMFS, so the screenshot dialog and view export both need browser download integration similar to existing file I/O. Macro recording saves .FCMacro files to MEMFS as well, which means saved macros are lost on reload without IDBFS persistence. QProcess is stubbed out on WASM (QT_FEATURE_process is disabled), so t  …
