2D Piping Symbols Library for AutoCAD
2D Piping Symbols
This 2D Library contains essential Piping Blocks for AutoCAD and AutoCAD LT, compatible versions 2006 through 2025.
This Piping Design tool is jam-packed with over 10,000 piping symbols that can easily be accessed using simple to use a pulldown menu provided by the program. The piping block library is also organized into categories to find them quickly!
You simply insert the piping symbol using the pulldown menus and dialog boxes provided to quickly generate piping plans, sections, and elevations. Just point and click. A red plus symbol indicates the base or insertion point of the block. Just insert into the drawing, rotate if needed, and you’re done.
Need 3D Piping Symbols? We’ve got some of those too! These high-quality 3D pipe symbols can be used with AutoCAD or LT. They also have similar features found in the 2D library, including one-step installation plus quick and easy menu access.
The image above shows how easy it is to access menus and pipe sizes.
This piping block library will save you hundreds of hours of drawing time.
Compare this library to other piping symbol packages costing hundreds, even thousands of dollars more!
Consider this: There are 10,841 piping symbols in this block library. A CAD operator making $18 per hour can create one symbol every two minutes, nonstop … or 30 symbols per hour.
We divide our 10,841 piping symbols by 30 piping symbols per hour, and you’ll get 361 hours of work. At $18 per hour, your CAD operator would be paid $6,498.00 to create this piping block library!
A Piping Block Library Ready To Go!
There’s nothing to learn. Just load the library in AutoCAD and go! This is a top-seller and its no wonder why.
Each symbol is drawn to a 1:1 scale on layer zero with “byblock” attributes. Once inserted, simply rotate the symbol into position, and it will take on the characteristics of your current layer settings.
Note: Pipe fitting insertion points are located at the intersection of the pipe centerline. Centerlines are not included with the blocks because they are usually on a separate layer and color.
