P&ID Master

Proving practical solutions for everyday problems with powerful process and instrumentation diagram software for AutoCAD


P&ID Master is a powerful process and instrumentation diagram software for AutoCAD. It is the perfect solution for a 2-D drafting tool in the engineering, maintenance and operation departments. P&ID Master makes the creation of smart process and instrumentation diagrams, loop sheets and other flow diagrams quick and easy.

P&ID Master provides an extensive library of ANSI/ISA linetypes and symbols. All components are easily inserted and manipulated on the drawing. The Layer Control System supports multiple setups and will automatically ensure that the correct layers are used. Reports can be generated in spreadsheet or database format. The P&ID Master Database Manager is fast and has all the capabilities to edit and generate accurate reports about the flow diagrams. P&ID Master has the flexibility, power and speed for all your drawing needs.


Over twenty-five different ANSI/ISA linetypes are available, all are under the users complete control for visual appearance.

A complete set of the ANSI/ISA linetypes are included with P&ID Master. The linetypes are created with the same ease as using the standard AutoCAD line command. P&ID Master supports AutoCAD complex linetypes and the original P&ID Master Classic linetypes. The Classic linetypes symbol spacing and scaling can be adjusted on the fly while you draw.

Various flow arrow sizes can be automatically placed on lines and additional linetype utilities are included for User-Definable linetypes, and linetype conversions.


P&ID Master symbols conform to ANSI/ISA standards. The instrument bubbles support long tag names and multiple justifications. Easy to use commands allow you to edit instrument bubbles and control valves. P&ID Master provides a complete database driven library of instruments, functions, control valves, actuators, tags, elements, fittings and equipment symbols.

Symbol Customization

The complete symbol library can be modified to comply with your company standards while maintaining the attribute and database control. You can create new symbols or use your existing symbols with P&ID Master.

Symbol Placement

You may select a symbol from the P&ID Master pull-down menu or toolbar. The P&ID Master automated symbol insertion will help place symbols on your drawing faster than ever and it will even do the cleanup around the symbol for you.

Layer Mangement

The Layer Control System lets the user define and control how layers are used in the drawing.  Multiple layer configurations are supported making you highly productive.

P&ID Master allows you to totally customize the properties of the layer templates that it uses. Several types of layer templates are provided to get you up and running quickly. With our Layer Control System all of the P&ID Master symbols and linetypes are placed on the layers you designate.


P&ID Master allows you to setup your own productive drawing environment. All the default settings can be modified and saved. You can easily change how P&ID Master operates, so all the drawings created will follow your company standards.


P&ID Master user interface is designed to quickly create Process and Instrumentation Diagrams to ANSI/ISA requirements.  All aspects of P&ID master are extremely easy to control.

P&ID Master comes with easy to use toolbar and pull-down menu. Our interface was developed by Piping and Instrumentation experts making sure each step of the drawing layout process has been designed to minimize the amount of time that it would normally take. P&ID Master also comes with complete documentation.

Report Generation & Bill of Materials

The P&ID Master Database Manager is a powerful tool that allows you to create an up-to-date bill of materials for a single drawing. You can print accurate reports of line numbers, valves, instruments, equipment and symbol tags. Reports can be printed or exported to an ASCII text file. The database structure and report format are completely user definable.

Included with P&ID Master is a complete symbol library of database driven blocks of instruments, functions, control valves, actuators, tags, elements, equipment and titleblocks.  Several styles of instrument bubbles and tags are supported.

P&ID Master can also automatically extract the drawing database to an external report file in spreadsheet or database format. Standard report templates are included for line number tags, instrument lists, valve lists, equipment lists and miscellaneous symbol tags.

Our Secret


P&ID Master now includes the latest version of ToolChest software. ToolChest adds to AutoCAD the "can’t do without" commands and hundreds of industry standard symbols, all at your fingertips. It’s no wonder ToolChest makes those impossible design and drafting tasks easy.
