AMS ClothWorks is a physics-based cloth simulation plugin developed by Anton Synytsia (AMS). Version 1.8.0 represents a significant update, bringing faster solvers, better collision detection, and improved stability.

If you do any interior modeling or soft-goods design, this is a must-have extension. It bridges the gap between SketchUp’s architectural strengths and the organic fluidity typically reserved for high-end software like Marvelous Designer.
