I have a mechanical invention that is ready for its US patent application and I need a clean, accurate 3-dimensional CAD drawing created in AutoCAD. The figure must meet USPTO standards for line weight, clarity, and labeling so that it can be inserted directly into the specification without extra editing on my end. You will start from my rough sketches and written notes (I’ll share them once we begin), translate every feature into a detailed 3D model, then generate the views typically required for patent filing—perspective, exploded (if useful), and any sectional or detail views needed to show the novel elements. Deliverables: • Native AutoCAD .dwg of the full 3D model • High-resolution PDFs (black-and-white) of each figure sized for USPTO submission • A quick reference image sheet so I can review and request minor tweaks before we finalize If you have experience preparing mechanical drawings specifically for patents, let me know; otherwise, solid AutoCAD skills and attention to USPTO line-art conventions are essential. I’m ready to move forward as soon as I see a portfolio sample that proves you can hit this level of precision.
