It's easy to use:

With a couple clicks of the mouse, you'll be able to quickly insert the symbols you need to generate piping & instrumentation diagrams with ease. By utilizing a pull down menu and dialog boxes, this block library organizes all of the symbols for easy and instant access.

How it works:

Once loaded in AutoCAD or AutoCAD LT, "PID Library" will appear in the menu bar.

Step 1: Choose a category of symbols from the pull-down menu.
Step 2: A dialog box appears showing all of the available symbols with a description to the left. The red dot indicates the symbol's insertion point. Choose the symbol you would like to insert and click on "OK"
Step 3: Insert the symbol in your drawing and rotate it to the correct position.
Details about the blocks:
  • Each symbol is drawn on layer zero with "bylayer" attributes.
  • Once inserted, the symbols will take on the characteristics of your current layer settings.
  • Valve and instrument symbols contain built-in attributes. You'll be prompted in the command line to input the information, or just leave it blank.
