Difficulty: Simple (TRIAL/PRO versions only)
A truss set up parametrically where the height and number of divisions can be altered. The Beam Joint component releases the joints of the diagonal members and the Tension Compression Eliminator eliminates all members under tension. Assigning beam ids allows various cross sections in one model. Reduce the truss divisions to view in the Trial version.
