Translating IFC geometry between Blender/Bonsai and Three.js requires mapping IFC schema objects and geometry references without mutating the source file. A lossless mapping framework extracts spatial structure and type objects to ensure accurate data transfer across BIM editors and web viewers.

Yes, web-ifc supports IFC4X3 schema mapping and spatial structure traversal when paired with a cross-tool mapping framework. The framework parses IFC4/IFC4X3 schemas to extract and merge property sets, quantities, and type objects while preserving spatial relationships across tools like IfcOpenShell and Three.js.

The best way to merge IFC property sets and quantities from type objects into web viewers is to use a cross-technology mapping framework that extracts and merges data from both occurrence and type levels. This approach preserves spatial structure and relationships for accurate BIM data translation to Three.js or Speckle.

Yes, you can map IFC data to Speckle pipelines without modifying the original IFC file by using a mapping framework that handles geometry referencing and property extraction without mutating the source. The framework reads IFC4/IFC4X3 schemas and generates cross-tool metadata for data pipelines.

IFC property set data gets lost during cross-tool conversion when the mapping process fails to merge property sets and quantities from both occurrence and type objects. A lossless mapping framework parses IFC4/IFC4X3 schemas and extracts type objects to ensure complete data transfer between tools like IfcOpenShell and web-ifc.
