I just downloaded a 30 day trial version of advance steel. I loaded in a drawing that I had from Revit, but when the file is imported into CAD, I do not know how to make a change to the beams to show which are existing and which are new, or if this is even possible. I saw in the Advance Steel starting guide it mentions that there is something in behavior tab under the advance properties of the beams but those options didn't seem to change anything. Anyone know how to do this?
