- src/freecad_mcp/server.py:84-85 (helper)Helper method in FreeCADConnection class that proxies the get_object RPC call to the XML-RPC server.def get_object(self, doc_name: str, obj_name: str) -> dict[str, Any]: return self.server.get_object(doc_name, obj_name)
- Backend RPC server implementation of get_object. Fetches the FreeCAD DocumentObject by name and serializes it using serialize_object.def get_object(self, doc_name, obj_name): doc = FreeCAD.getDocument(doc_name) if doc: return serialize_object(doc.getObject(obj_name)) else: return None
- Serialization helper function used to convert FreeCAD objects to JSON-serializable dicts. (Full function spans multiple lines including recursive serialization.)def serialize_object(obj): if isinstance(obj, list): return [serialize_object(item) for item in obj]
