3D Warehouse Layout Model

I have an existing warehouse plan that lives only in my head and a few notes—no CAD files, blueprints, or tidy sketches. I will walk you through the exact dimensions, column positions, doors, and racking zones, and I need you to translate that verbal description into a clean 3-dimensional model...
