How do I get IFC data for quantity takeoff?

Open QTOpro, choose a template or create one, then drop your IFC file. The app extracts IFC data locally and lets you export CSV/XLSX for quantity take‑off and Bill of Quantities.

Can I generate an IFC Bill of Quantities (BoQ) in the browser?

Yes. Use templates to define measurements and metrics, then export results to Excel to produce a Bill of Quantities from IFC data.

Do IFC files get uploaded to servers?

No. QTOpro processes IFC files locally in your browser; no server uploads are required.
