Scale-Accurate 3D Sign Render

I have complete 2D artwork for a sign and now need it transformed into a fully navigable 3D model that matches the real-world piece exactly. Above all, the dimensions and overall scale must be spot-on, as I will be checking measurements once I’m able to orbit, pan and zoom around the model in a free viewer. Because I’ll be showcasing this piece up close, please build it with high detail: sharp edges, crisp bevels, and faithful reproduction of any raised or recessed elements in the artwork. Realistic textures are welcome, but only if they do not compromise measurement accuracy. When you hand it over, I need: • The finished 3D file ready for any no-cost viewer (Sketchfab, Autodesk Viewer, etc.) • A quick test link or set-up notes so I can immediately load, spin and inspect the sign from every angle. • Confirmation that all major measurements match the source drawing. Feel free to propose the best file type for friction-free viewing—FBX, OBJ, or another common format is fine as long as it opens without paid software. Let me know your preferred workflow and the timeframe you need, and we can get started right away.
