Features

• Model Loading: Load single or federated IFC models with automatic geometry caching
• Data Querying: Extract properties, quantities, materials, classifications, and relationships
• Smart Filtering: Filter elements by attributes, properties, quantities, spatial containment
• Geometry Extraction: Convert IFC geometry to Dynamo meshes and bounding boxes
• Clash Detection: Detect hard clashes, soft clashes, and clearance violations
• AI-Powered Chat: Chat with your IFC model using natural language (requires Google AI API key)
• 3D Visualization: Built-in viewer with highlighting and isolation capabilities
• Schema Knowledge: Query IFC4x3 schema without loading a model

Installation

Option 1: Dynamo Package Manager (Recommended)

1. Open Dynamo
2. Go to Packages > Search for a Package
3. Search for "IFCNodes"
4. Click Install

Option 2: Manual Installation

1. Download the latest release from the Releases page

• Dynamo 2.x or later (tested on 2.19.0)
• Windows 10/11 (64-bit)
• .NET Framework 4.8 or later

Quick Start

1. Add IFCReader.LoadIFCModel to your canvas
2. Connect a file path to load your IFC file
3. Use IFCFilter nodes to select elements
4. Use IFCQuery nodes to extract data
5. Use IFCViewer to visualize results
