The prompt
Generate a parametric 3D CAD model of a steel access platform with stairs in millimeters based on the following engineering specifications: 1. Support Foundations: 6 concrete pedestals measuring 400mm x 400mm x 250mm high. 2. Main Columns: 6 vertical structural pipes made of 6-inch Schedule 40 (6" Sch 40) steel, positioned directly on top of the pedestals. 3. Upper and Intermediate Platform Frames: The outer perimeter of both platforms must be constructed using C6x8.5 lbs/ft steel channels. The internal structural crossbeams must use C4x5.4 lbs/ft steel channels. 4. Flooring: Lay open steel bar grating across the walking surfaces of both platforms. 5. Access Stairs: Stair stringers made from C6x8.5 lbs/ft steel channels. The stair treads must be constructed from 1 1/2" x 1/4" square steel angles. Maintain all connections as a standard industrial structural assembly.
