Can rigid and/or flex run under a beam? Say you have rigid duct running along the centerline of a beam. The flex runs perpendicular from the centerline of the beam and into spaces on either side. The rigid, by being drawn parallel under the beam, is within the 2' zone on either side of the beam. Is this acceptable?
Much of the discussion about beams seems to be about drawing rigid or flex perpendicular to a beam. It sounds silly to ask after reading the program but I'm paranoid at this point.
Rigid ducts fit under beams, in spaces between joists, and in a zone that extends 2 ft on either side of beams and bearing walls in plan view. Rigid ducts do not fit through joists or between the bottom of joists and the ceiling.
I found similar discussion in this thread way back.
