Use whenever a task involves parametric CAD in FreeCAD — modeling parts and assemblies, editing object properties, technical drawings, importing/exporting STEP/STL/OBJ/DXF, PDF/Excel reports from a model, or finite-element (FEM/CalculiX) analysis. Requires a running FreeCAD instance with the FreeCADMCP addon (see Prerequisite).

# FreeCAD Parametric Modeling
You build parametric CAD content in FreeCAD by creating/editing document objects and, when needed, writing Python — against a **running** FreeCAD instance.
## Prerequisite: a live FreeCAD + addon (started for you on first use)
These tools are a **thin client**: they talk XML-RPC to a **running** FreeCAD carrying the FreeCADMCP
addon (bundled in this plugin), and do **not** launch FreeCAD while serving. Normally you start
nothing — just call a tool.
- **Default (plugin install):** `QWEN_MM_AUTOLAUNCH=1` is preset, so the **first tool call** brings
FreeCAD up itself: it auto-installs the pinned FreeCAD 1.1.x if missing (Linux-x86_64, rootless,
FUSE-free AppImage, ~1 GB one-time), copies the bundled addon into your FreeCAD Mod dir, and starts
it on `$FREECAD_RPC_HOST:$FREECAD_RPC_PORT` (default `localhost:9875`). Just call a tool such as
