I’m developing a new mechanical component and need precise 3D models created directly in AutoCAD. The work is strictly mechanical design—no electrical or civil cross-overs—so familiarity with standard mechanical tolerances, fits, and industry drawing conventions is essential. My priority is an accurate, parametric 3D model that I can update as dimensions evolve. If you normally build in SolidWorks or CATIA, that’s fine as long as the final files land in AutoCAD format without loss of fidelity; native .dwg is my preferred end point. Deliverables • Fully editable AutoCAD 3D model of the part/assembly • Exported STEP or IGES file for downstream simulation • A short drawing pack (PDF) showing critical dimensions and exploded view I’ll share sketches and reference dimensions once we start, and I’m available for quick calls to clarify any subtle geometry. Let me know your typical turnaround time and the version of AutoCAD you’ll use so we can keep everything compatible.
