Then you know how hard it can be to get everyone to consistently classify model elements. Whether you're using Uniclass, eBKP-H, or your own system, getting teams to properly implement `IfcClassificationReference` is often a pain.\n\nAfter initially thinking about how to fully automating this process, I quickly realized that regulations, responsibilities across disciplines, and accountability requirements make that approach less practical.\n\n## ✨ What This Tool Does\n\nIFC Classifier helps you classify IFC elements without needing expert knowledge of BIM authoring tools. It's designed to make the process simpler and more repeatable.\n\n**Note:** This is a **Work In Progress** and open source under the **AGPL v3** license.\n\n## 🏗️ Architecture Overview\n\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd width=\"70%\"\u003e\n\n### Tech Stack\n![Tech Stack Architecture](docs/assets/IfcClassifier-tech.excalidraw.png)\n\n\u003c/td\u003e\n\u003ctd width=\"30%\"\u003e\n\n\n![Data Flow Diagram](docs/assets/IfcClassifier-flow.excalidraw.png)\n\n\u003c/td\u003e\n\u003c/tr\u003e\n\u003c/table\u003e\n\nThe application follows a modern web architecture with:\n- **Frontend**: Next.js + React with TypeScript for type safety\n- **3D Visualization**: Three.js with React Three Fiber for IFC model rendering\n- **IFC Processing**: web-ifc for parsing and IfcOpenShell via Pyodide/WASM for advanced operations\n- **Styling**: Tailwind CSS with Shadcn/ui components for a consistent design system\n- **Privacy-First**: All processing happens locally in the browser - no data leaves your device\n\n## 🌟 Features\n\n- **🖼️ IFC Viewer:**\n\n  - View IFC models in your browser\n  - Standard navigation (orbit, pan, zoom)\n  - Easy model exploration through spatial tree\n  - Check element properties\n  - Hide/show elements as needed\n\n- **📖 IFC Schema Documentation:**\n\n  - **Real-time schema previews:** Hover over IFC class names to see instant schema information\n  - **Full documentation reader:** Click \"View Schema\" to open comprehensive IFC documentation\n\n- **📚 Classification Systems:**\n\n  - Use ready-made systems:\n    - 🇨🇭 Swiss CRB eBKP-H\n    - 🇬🇧 Uniclass\n  - Or create your own custom system\n  - Assign colors to visualize different classifications\n  - Import or export classification sets as **JSON** or **Excel** files\n\n- **⚙️ Rule-Based Sorting:**\n\n  - Create rules to automatically sort elements\n  - Based on properties like: `IsExternal`, `LoadBearing`, etc.\n  - Example: \"Put all external, non-load bearing walls (except basement) into category C02.01\"\n  - See rule results live on your model\n  - Import rules from JSON or Excel for easy setup\n  - Export rules to JSON or Excel for sharing\n\n- **✍️ Export Your Work:**\n\n  - Save your model with proper `IfcClassificationReference` entities\n  - Use the improved file in other BIM tools\n\n- **🔎 Search \u0026 Filter:**\n\n  - Search across the model tree or entire 3D scene\n  - Cancel long searches and track progress\n  - Quickly hide or unhide found elements\n\n- **📋 Property-Based Classification:**\n\n  - Support for classification codes stored in property sets (Psets)\n  - Automatically map full classifications from existing Psets\n  - Extract classifications from existing property values in the model\n  - Flexible property set name matching with wildcard support\n\n- **🗣️ Multi-Language UI:**\n\n  - English, French, Italian and German built in\n  - Switch languages from the menu or settings panel\n  - Add new translations via simple JSON files\n\n- **🔐 Privacy First:**\n\n  - All processing happens locally in your browser\n  - IFC data never leaves your device\n  - Open DevTools → Network to confirm no IFC file is uploaded\n\n## 🚀 Recent Updates\n\n**July 10, 2025:**\n\n- README update, added architecture overview diagrams\n\n**May 23, 2025:**\n\n- Added comprehensive schema preview and documentation reader for IFC classes\n- Integrated schema preview tooltips and \"View Schema\" links \n\n**May 22, 2025:**\n\n- Added search across the 3D view and model explorer with progress feedback.\n- Implemented automatic mapping of classifications from property sets with wildcard support.\n- Introduced central IFC property caching for faster lookups.\n- Improved language selection menu and settings layout.\n- Refined properties panel and overall UI styling.\n\n**May 21, 2025:**\n\n- Added ability to import rule definitions from Excel (.xlsx) files.\n- Added ability to export rules to Excel for easier sharing.\n\n**May 20, 2025:**\n\n- Enhanced user interface with footer improvements.\n- Added settings for managing rules and default classifications.\n- Implemented IFC GUID display with a copy-to-clipboard feature in the properties panel.\n- Major refactor of classification and IFC model components for better performance and readability.\n- Fixed an issue to preserve model coordinates when loading new IFC files.\n- Improved layout and introduced a rule management menu for easier access.\n- Added functionality to import and export classifications as JSON files.\n- Added favicons for better cross-browser compatibility.\n- Enhanced property extraction and rendering from IFC models.\n\n**May 19, 2025:**\n\n- Introduced 3D selection-based classification, allowing manual assignment of classifications to selected elements.\n- Refactored and cleaned up code in ModelInfo and SpatialTreePanel components.\n- Fixed a bug related to null values for IFC class names in the spatial tree.\n- Added display for material sections and improved IFC model property extraction.\n\n**May 18, 2025:**\n\n- Initial project setup and README creation.\n\n## 💡 Goal\n\nMake IFC classification simple enough that anyone can do it properly.\n\n## 🛠️ Tech Stack\n\n- [Next.js](https://nextjs.org/)\n- [React](https://reactjs.org/)\n- [TypeScript](https://www.typescriptlang.org/)\n- [Three.js](https://threejs.org/) / [@react-three/fiber](https://docs.pmnd.rs/react-three-fiber)\n- [web-ifc](https://github.com/IFCjs/web-ifc)\n- [IfcOpenShell](https://ifcopenshell.org/) via Pyodide/WASM\n- [Tailwind CSS](https://tailwindcss.com/)\n- [Shadcn/ui](https://ui.shadcn.com/)\n- [Radix UI](https://www.radix-ui.com/) -
