Modern Goat Shed CAD Design

I’m developing a 120 ft × 70 ft goat shed with a contemporary look and need a complete CAD package to move the project into fabrication. The structure will have a gable roof, steel columns and trusses, a full slatted flooring support system sitting 5 ft above grade, and GI sheet roofing...
