DraftToolbox was founded to provide fast, precise, and completely accessible geometric and dimensional layout calculators for web browsers. Our suite of 17 dedicated tools covers standard architectural framing formulas, mechanical toolroom machining specs, industrial pipefitting offsets, and structural carpentry layouts.
Our ongoing mission is to eliminate multi-step blueprint math mistakes by providing clean, ad-supported calculating interfaces that shop technicians, engineers, and DIY builders can run on any smartphone or tablet directly on the job site.
