Open IFC Viewer
Open IFC Viewer is a free desktop tool for opening and reviewing IFC building information models.
What Open IFC Viewer is
Open IFC Viewer is a free desktop tool for opening and reviewing IFC building information models. It runs on Windows, macOS, and Linux, and processes files locally without a cloud dependency. Its listed IFC support includes IFC 2x3, 4x0, 4x2 Bridge, and 4x3 Rail. Review tools include 3D navigation, object selection and property inspection, hiding or isolating objects, and section planes. Users can measure distances and angles, detect collisions between model objects, and save collision results in BCF format. Model Validation checks models against IDS and other stated SDAI or IFC requirements, with results that can be filtered and saved as text or HTML. Open files can be exported to PDF, HDF5, and ifcXML, and IFC models can be published to 3D PDF. The viewer also includes a BCF Manager and an embedded IFC MCP Server for a connected AI agent. The guide notes that spaces are not imported by default, two plugins are experimental, and schedule timelines require schedule data in the model.
