Parametric PosiJoist model for Revit 2013. Parametric length, number of end noggings, their visibility and start/end angle cut-off each side separately - from 90º (square) down to 10º (very sharp angle). This is the 302mm high posi strut (height is fixed) but the top and bottom chords are parametric size. The number of posi brackets change automatically with joist's length.
