I have a complete set of legacy CAD files for a small precision-machined assembly that now needs a thorough refresh. Using AutoCAD as the main platform, I want the overall assembly structure rebuilt first, then any knock-on tweaks to individual part dimensions or tolerances handled as they surface during the process. All reference STEP models, PDF prints, and mark-ups are ready for you as a starting point. Here is what I expect back: • A clean, fully-parametric 3D assembly model that reflects the updated design intent • Manufacturing-ready 2D drawings with clear views, call-outs, and revised GD&T where required • Final deliverables supplied in both STEP and native DWG formats (additional PDFs are welcome but not mandatory) Accuracy is critical; these files go straight to prototype machining, so hole locations, fits, and stack-ups must be spot-on. I will share a simple NDA before we start and stay available for quick design reviews to keep momentum high. If you have a solid background in machined components, assemblies, and design-for-manufacture—and you are happy working in AutoCAD—let’s move this update forward.

Hi, I have extensive experience in AutoCAD mechanical design, precision-machined assemblies, and manufacturing documentation. Using your legacy CAD files, STEP models, PDFs, and mark-ups, I can rebuild the assembly structure into a clean, fully parametric model, update individual components as required, and ensure all dimensions, fits, tolerances, and stack-ups accurately reflect the revised design intent for prototype machining. My background includes preparing production-ready 2D drawings with detailed GD&T, machining call-outs, and assembly documentation that manufacturers can confidently work from without further clarification. I understand the importance of accuracy when files move directly into fabrication and can work efficiently through review cycles while maintaining organized DWG and STEP deliverables. Could you please confirm which AutoCAD version the final native files should be delivered in? I look forward to assisting with your project. Best Wishes.
