This library can be easily loaded into AutoCAD's menu bar for quick access. There's no need to browse through folders every time you need to insert a symbol. Its user-friendly interface allows you to simply point and click to choose from over 4,500 3D solid model pipe fittings and valves. This demo version contains a small sample of symbols and will function the same as the full version. Everything included in the full version of this library will be listed in the demo's pulldown menu.
