A free online IFC viewer — and a lot more
Sometimes you just need to open an IFC and look at it. Drop it into ClashControl — no install, no account. Orbit the model in 3D, slice it with section planes, inspect element data, and validate it against an IDS.
And when "just looking" becomes "wait — do these clash?", clash detection and BCF export are right there in the same tab. Most online viewers stop at viewing. This one keeps going.

- Is there a file size limit?
- No hard limit. Practical model size depends on your browser's memory — typical workstation browsers comfortably handle multi-hundred-megabyte IFCs. Larger or federated models can be parsed in the optional localhost engine.
- Does my model upload to a server?
- No. IFC parsing and viewing run fully client-side in your browser. Nothing is uploaded.
- What else can it do beyond viewing?
- Hard and soft clash detection, BCF 2.1 / 3.0 import and export, IDS validation, data quality checks, and a live link to Revit for two-way sync.
