IFC Federator

IFC Federator is a focused BIM coordination app for importing multiple IFC models, reviewing them together, and exporting one combined IFC file.

Built for IFC federation workflows, the app helps you bring discipline models together — architecture, structure, MEP, civils and more — before producing a source-preserving combined IFC export.

KEY FEATURES

• Import multiple IFC models
• View models together in a federated 3D scene
• Export multiple same-schema IFCs as one combined IFC file
• Preserve source geometry, GUIDs, placements and property data
• Safely renumber STEP entity labels to avoid source-model collisions
• Review loaded, visible and hidden models
• Fit all models or fit a selected model
• Toggle model visibility
• Reopen exported IFC files for checking
• Generate a secondary CSV coordination report
• Use the AI Coordination Assistant for plain-English guidance based on app-generated model facts

SOURCE-PRESERVING IFC EXPORT

IFC Federator’s V1 combined export is designed to preserve source IFC data rather than remodel it.

The app combines compatible same-schema IFC files into one IFC/SPF file, creating one clean HEADER section and one DATA section while safely renumbering STEP labels and preserving the original IFC entity content.

For safety, mixed-schema export is blocked. For example, IFC2X3 and IFC4 files should not be silently merged into one file.

COORDINATION-FIRST VIEWING

Use the federated viewer to check that models load together, review visibility, fit all models, focus selected models, and inspect basic federation state before export.

The app helps identify common coordination concerns such as model count, schema compatibility, bounds, large coordinate ranges, and export readiness.

AI COORDINATION ASSISTANT

The built-in assistant explains the current federation and export state in plain English. It is grounded in app-generated facts and is not a certified validation result.

Where Apple Intelligence or Foundation Models support is available, the app is ready to use Apple-provided local capabilities. Where unavailable, the assistant uses deterministic local summaries. No external paid AI API is required.

IMPORTANT NOTES

IFC Federator does not automatically rewrite model coordinates, regenerate GUIDs, remodel storeys, or repair source IFC geometry. It is designed for source-preserving IFC federation and export.

For best results, use clean IFC files exported from your BIM authoring tools with compatible schemas and coordinated project origins.
