I love all the joist families that came with Revit starting in version 9. However I need a joist girder family where I can either specify the slope of one chord (preferably the bottom) or let me specify the depth at each end of the joist independently. We have some joist girders on a project that taper down towards the outside wall to allow more vertical clearance near the wall, and I'd like to model/show them correctly.
