To load IFC files, initialize the FragmentsManager, configure the IfcLoader with correct WASM paths, and pass a Uint8Array of the IFC bytes to the load function. This ensures safe WASM setup and converts the model into fragments for viewer display.

IfcLoader is a high-level approach for loading models directly into the viewer, while IfcImporter is a low-level tool for server-side processing or web workers. IfcImporter also provides hooks like onIfcImporterInitialized to tailor imported classes.

WASM path configuration errors are fixed by setting manual path setup or using automatic resolution to prevent version mismatches between compiler and runtime. Proper WASM configuration ensures safe imports and reproducible fragment workflows.

Yes, you can read raw IFC data for debugging by using the low-level IfcImporter. This provides optional raw web-ifc access, allowing you to inspect imported classes directly before or without executing the fragmentation workflow.

You convert IFC to fragments by configuring the IfcLoader or IfcImporter and executing the fragmentation workflow. This process transforms IFC data into fragments, producing a cached format that enables fast model reloading in ThatOpen viewers.

Use the IfcImporter for server-side processing, web worker integration, or when you need raw web-ifc access for advanced debugging. Use the high-level IfcLoader for standard component-based workflows to display models directly in the viewer.
