Mechanical floor plans, duct and piping layouts, equipment schedules, control diagrams, riser diagrams, and isometrics — reading and producing the drawing set a real project actually runs on.
Every calculation in this program — load calcs, duct sizing, hydronic pipe sizing, refrigerant piping — eventually has to land on paper in a form a contractor can actually build from and a reviewer can actually check. This module teaches the drawing types that carry that information: what a mechanical floor plan shows versus what it deliberately leaves to the equipment schedule, why a four-pipe hydronic system needs four real piping runs drawn to every coil, and why an equipment schedule that's internally inconsistent with its own listed conditions is one of the most common submittal-review findings on a real project.
It also teaches the reading order experienced engineers actually use on an unfamiliar set — schedules first, then plans, then layouts, then risers and isometrics, then control diagrams last — and the cross-sheet consistency checks that catch a late design change one sheet picked up and its companion sheet missed.
