Trades & Professional Tools
Choose your industry first, then open a calculator built around the measurements, materials, machines, and intermediate outputs that work actually uses. The catalog now includes construction, service, welding, digital fabrication and laser, automotive, surveying, and heavy-equipment workflows. Local code, qualified procedures, machine data, test criteria, product limits, and site decisions remain explicit professional inputs.
