Okay so i was doing my HVAC/sheet metal drafting all smoothly, doing all the hvac and vents. until, suddenly, and with out warning, an instruction from the booklet was so confusing, i momentary cannot find out what to do. this is my questions in which im stuck. 3. The eastern portion of the split is 10″ wide and connects almost immediately to a 10 × 14 transition piece. The 14″ × 6″ duct continues south to a point near the sink in Bathroom #2 where it splits into two portions. 4. The west portion forms a 4″ × 4″ duct that bends west and connects immediately to the wall outlet scheduled as S-B2. This outlet is located in the toe clearance between the washbasins in Bathroom #2. The 4″ × 4″ duct exits from the west side of the outlet and continues west to end in Bathroom #1. The very end of the duct connects to the 4″ × 12″ wall outlet scheduled as S-B1. Like the other bathroom’s outlet, this outlet in Bathroom #1 is positioned in the toe clearance between the washbasins. so far i have no understanding of what it means. what are toe clearances? this my work so far plate 1.dwg so can u give me a brief explanation. anyone that helps gets a virtual cookie.
