🏗️ IFCflow

A visual node-based tool for working with Industry Foundation Classes (IFC) files

---

📋 Overview

IFC Flow Map provides a graphical interface for viewing, filtering, transforming, and analyzing Building Information Modeling (BIM) data through an intuitive workflow system. Create complex data manipulation pipelines with a simple drag-and-drop interface.

✨ Features

• 🔄 Visual Node-Based Interface - Create workflows by connecting nodes in a flow diagram
• 🏢 IFC File Support - Load and analyze IFC files for BIM data
• 🧩 Multiple Node Types:
  • 📁 IFC Node - Import IFC files
  • 📐 Geometry Node - Extract geometric information
  • 🔍 Filter Node - Filter elements based on properties
  • 🔄 Transform Node - Apply transformations to elements
  • 👁️ Viewer Node - Visualize 3D models
  • 📏 Quantity Node - Extract quantity information
  • 🏷️ Property Node - Work with element properties and property sets
  • 🔖 Classification Node - Manage element classifications
  • 📍 Spatial Node - Perform spatial queries
  • 💾 Export Node - Export data in various formats (CSV, JSON, IFC)
  • 🔗 Relationship Node - Query element relationships
  • 📊 Analysis Node - Perform analyses like clash detection
  • 👀 Watch Node - Monitor element values
  • ⚙️ Parameter Node - Define workflow parameters
• 💾 Workflow Storage - Save and load workflows
• ⚡ Real-time Execution - Execute workflows and see results immediately
• ⌨️ Keyboard Shortcuts - Efficient workflow creation with keyboard shortcuts
• 🔄 Advanced Property Handling - Get, set, add, and remove properties in IFC elements
• 📤 IFC Export - Export modified IFC files with your property changes
• 🧰 IfcOpenShell Integration - Leverage IfcOpenShell 0.8.1 for reliable IFC processing

🚀 Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the application.

📖 How to Use

1. Create a New Workflow - Start with a blank canvas
2. Add Nodes - Drag and drop nodes from the sidebar
3. Connect Nodes - Create connections between node inputs and outputs
4. Load IFC Files - Use an IFC node to import your BIM data
5. Configure Node Properties - Set properties in the properties panel
6. Execute Workflow - Run the workflow to see results
7. Save Your Workflow - Save workflows for later use

🛠️ Working with IFC Properties

1. Get Properties - Use the Property Node with "Get" action to extract properties like "IsExternal" from walls
2. Set Properties - Modify existing properties or add new ones with the "Set" action
3. Connect Property Nodes - Chain property operations by connecting nodes
4. Export Modified IFC - Use the Export Node with "ifc" format to save your changes

📚 Technical Details

• Web-Based Processing - All IFC processing happens client-side using WebAssembly
• IfcOpenShell Integration - Uses IfcOpenShell 0.8.1 via Pyodide for robust IFC handling
• Property Management - Comprehensive property handling across property sets (Psets) and quantities
• JSON-Based IFC Model - Efficient conversion between IFC and JSON for manipulation
