FAQ

Is an IFC file uploaded to a server?

Not in the local Viewer/WASM flow. The browser reads the file and the Rust core runs in WASM. The MCP server reads a local path visible to its process.

Maximum file size?

A WASM input session is limited to 128 MiB; the claimed alpha target is up to 100 MB. Native limits are different and do not define the browser SLA.

Does editing a property change 3D geometry?

An ordinary Pset value does not change a mesh. Placement or geometry edits need a supported schema-aware operation and geometry rebuild.

API versus SDK?

An API is the callable surface and DTOs. An SDK packages the API with types, helpers, examples, and documentation. A separately published SDK does not exist yet.

Does MCP call an LLM?

No. It exposes deterministic read-only tools. Any LLM and network orchestration must remain outside the core.

IFC2X3 and IFC4X3 support?

Schema metadata exists, but the 0.2 release SLA is limited to IFC4 ADD2 TC1 IFC-SPF.
