Hi everyone,

I have a sloped round duct from which I want to take off rectangular ducts.  I dunno why, but Revit does not understand what I am trying to do.  The main round sloping duct is running horizontally, and the rectangular duct take-offs go up vertically to the finished floor.  I want these rectangular ducts to rise straight up plumb & true, not perpendicular to the main sloping duct.  Revit keeps giving me warnings/errors.

Hope someone can help!
