What this is and isn't
These are design-intent drawings, not shop drawings, and not a substitute for a Revit family. The dimension set is now taken from the Hamilton MCL cut sheets — ¾″ TFL construction, interior width less 1½″, interior depth less 15/16″, MCLY 4″ base, and the 20″ minimum depth for a hanging rod, which the engine enforces by swapping in coat hooks below it. Heights are quoted as carcass; overall adds the base and the nameplate header. The platform line under each configuration says whether it is an HCS standard size, a custom size inside the 12–24″ / 36–90″ range, or outside the platform entirely.
On the ventilation figure
Face free area is computed from the elevation — open zones over gross face. The base figure is a specified minimum for the vent panel, not a measurement. It is the number a mechanical engineer will ask for, and it exists so the ventilation can be described by what it is rather than by what it might do. Passive stack manages odor and moisture; it does not dry a practice load, and nothing on this page should be quoted as if it does. Duct connection can be accommodated as a quoted special — it is deliberately not a published option.
