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 1 — Workbench inventory & classification. For EVERY module in src/Mod, determine: is it C++/Python/mixed; its build dependencies (read each CMakeLists.txt); whether it's currently built (see live list); its user-facing purpose; and a first-cut viability+effort to enable if missing. Read src/Mod/*/CMakeLists.txt and src/Mod/*/Init(Gui).py imports. Produce one gap entry per MISSING module with concrete enable requirements. This is the master inventory the roadmap is built on.

I'm starting with Dimension 1 by examining each module in src/Mod, checking their CMakeLists.txt and Init/InitGui.py files to identify which ones are missing from the inventory, then I'll create gap entries for those.

Show's Python tree is packaged as a dependency, but numpy and matplotlib aren't available anywhere, which means any module that relies on them—like Draft's utilities, Fem's core functionality, Plot, and BIM—would need numpy compiled for WebAssembly. Let me check whether Draft actually depends on numpy at its core by looking at the imports I found earlier, and it looks like Draft doesn't require it after all, though it does import Part and needs DraftGeomUtils. Now I'm checking what C++ libraries like SMESH, Netgen, and VTK are available in the WebAssembly build tree, since Fem and MeshPart depend on them.

Looking at what's available in the codebase, SMESH is already there in the source tree, which means Fem and MeshPart could potentially be compiled for WebAssembly, though it would require porting SMESH since it depends on OCCT and optionally Netgen. The good news is that Netgen is optional, so it's not a hard blocker. OndselSolver is also in-tree, making Assembly's solver relatively straightforward to build. And libE57Format is already present and being built.

Points is straightforward since libE57Format is already available in the build tree. CAM's libarea is in-tree and buildable. However, several modules hit hard constraints: VTK, PCL, gmsh, netgen, and calculix aren't available for WebA  …

All the missing modules are BUILD_*=OFF, and BUILD_SHOW is ON for the Python tree package, while BIM is confirmed OFF. Now I need to verify the Draft InitGui dependencies—Draft relies on Part and is a critical 2D workbench that shouldn't have any missing module issues.

I'm also checking whether Draft's C++ utilities are lightweight, then examining Draft's app library dependencies and how BIM interconnects with Draft, Arch, Part, Points, and TechDraw. Since BIM is substantial and ifcopenshell brings 82 files with its own C++ dependencies for WebAssembly compilation, I need to quickly review TechDraw's Qt dependencies like QtSvg before finalizing my analysis.

I'm checking whether the ReverseEngineering module's PCL dependency is truly optional or if it's being linked unconditionally — the CMake guards suggest PCL is optional with fallback approximation via OCCT and GSL, but I need to verify that Reen_LIBS doesn't reference PCL variables unconditionally since empty variables would still attempt linking.

Now I'm ready to map out the full gap analysis across all 22 missing modules, categorizing them by viability and effort. For pure-Python modules like Draft and Show, the path forward depends on runtime dependencies and optional external tools — Draft's DXF import works natively but DWG import requires an external ODA converter, making that particu  …
