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. :cry:

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.

Toe Clearance ? The kick space at the base of any cabinet, approx 3x3 space at the bottom of the cabinet. When standing at a cabinet your toes would hit the cabinet if the face continued flush to the floor, but at the bottom the cabinet juts in and then down giving you a place for your toes. With heating coming from that space it makes it comfortable while standing in front of the mirror, etc. Chocolate chip for me please.
