An involute rack's outline, in the sketch's coordinates, as parts.mechanical.gears.rackProfile draws it:
start is where the first tooth's middle sits on the pitch line, angle turns the rack from
running along +x (in degrees), module and teeth size it, and the other numbers shape the teeth
as that method's inputs do, with the same defaults. A gear meshes with its centre its pitch radius
from the pitch line. It is a loop by itself, so it is the only command of its pen or loop. The faces
made of it are named by its id and their part: tip, flank, root, back and side.
