thatopen-core-web-ifc

What problem does it solve?

Directly access the web-ifc engine to parse IFC data, query entities, and extract geometry from ThatOpen components, enabling fine-grained control over the parsing lifecycle and memory management.

Core Features & Use Cases

• Direct low-level IFC access: SetWasmPath, Init, OpenModel, GetLine, GetFlatMesh, StreamAllMeshes, and property helpers.
• Geometry and data extraction: retrieve vertex data, indices, and per-entity transforms with schema-aware type handling.
• Model lifecycle and coordination: support multiple models, coordinate alignment, streaming workflows, and COORDINATE_TO_ORIGIN options.
• Typical use cases include custom IFC viewers, analytics tools, and research pipelines that require deterministic parsing and precise geometry data.

Quick Start

Initialize the IfcAPI by setting the WASM path and calling Init, then load an IFC buffer with OpenModel and begin querying geometry and properties.
