To load and render IFC models in Three.js, use the web-ifc library and @thatopen/components to parse BIM data and stream large files directly into a Three.js scene with spatial hierarchy and property extraction enabled.

You should avoid deprecated web-ifc-three because it introduces licensing pitfalls and lacks active support. Using MIT-licensed web-ifc with @thatopen/components provides a safer, license-aware workflow for rendering IFC files in Three.js.

The best way to stream large IFC files in a web browser is using the web-ifc library to enable streaming, which allows Three.js to load heavy BIM models efficiently while maintaining safe memory management and accessing property metadata.

Yes, you can extract spatial hierarchy and properties from IFC data in Three.js by using @thatopen/components to construct spatial trees that reflect the building hierarchy and read IFC metadata for elements and relationships.

web-ifc is MIT-licensed and safe for commercial BIM applications, but you must be aware of AGPL licensing implications when integrating related packages. This workflow guides you between MIT-licensed web-ifc and AGPL components to ensure compliance.

Limitations of using Three.js for IFC viewer applications include managing memory safely when streaming large BIM files and navigating the licensing complexities of deprecated packages, requiring careful integration of web-ifc and @thatopen/components.
