I have a set of engineering drawings and I need them turned into precise 3D models ready for manufacturing. The final deliverables must be: • A fully-defined 3D model of each part, built exactly to the dimensions and tolerances shown on the drawings • Clean, watertight STEP (.stp) files suitable for CNC machining and other downstream production processes The geometry has to mirror the drawings one-to-one—no assumptions or artistic liberties. Fillets, chamfers, threads, and any GD&T callouts on the prints should be incorporated so the factory can rely on the files without further edits. Preferred tools are SolidWorks, Inventor, Fusion 360, or any professional CAD platform that exports true STEP data. If you spot missing or conflicting dimensions, flag them before modeling so we can clarify early. Once the STEP files pass a quick fit-check on my side, the job is done.
