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 a wide range of piping symbols. The "Piping Symbols Library version 1.2" comes with over 14,000 symbols. This demo version contains a small sample of symbols (4" only) and will function the same as the full version. All of the symbols included with the full version will be listed in this demo's pulldown menu.
