Premium Parametric Window Collection of Revit families. A modular window system where every unit is assembled from interchangeable nested parts – sashes, transoms, casings, exterior and interior sills and handles – changed in seconds right in the project, without opening the family editor. Choose swing, tilt-turn, fixed or sliding sashes, add muntins per sash type, set separate finishes for frame, sash and casing, and flip any window between inswing and outswing with one parameter. Clean graphics at every Detail Level, ready-to-use schedules and templates for your own components. User's manual and demo project included.
