I have a set of detailed sketches for a die-cast car model and need the exterior body translated into production-ready CAD. The work is limited to the outer shell — no interior or engine components — but the surfacing must read as a true car body once cast in metal. Your task: Build a clean, parametric 3D model in Unigraphics (NX) or any software that can export production-ready STEP files suitable for die-casting. Accuracy in automotive-grade surfacing is essential — the curves, shut-lines, and panel transitions must look authentic at scale and remain manufacturable for the die-casting process. Deliverables: • Body shape & primary surface definition • Windows, pillars, and exterior trims • Wheels and tires to match the provided sketch dimensions I will supply reference drawings, critical dimensions, and any branding marks at project start. Please keep the CAD model well-organized (clearly named layers / features) so future revisions are straightforward. When handing over the final STEP file, include: • A short note on the unit setup (mm/inches) • Any assumptions made during modeling If you routinely check for draft angles or under-cuts for tooling in NX, please mention that — those insights will speed up review and approval. I’m happy to do one or two milestone reviews to confirm we’re on track before final delivery.
