How do I go about to create a tapered wide flange beam [e.g. 18" high on one end and 6" on the other]? I'm not acquainted with family creation/changing yet, so if that's what I need to do first I think I already found a tutorial on that.
Thanks,
Axel
P.S.: The attached picture is a Sketchup screenshot where I manipulated the Revit beam.
