Piping and Instrumentation Diagrams (P&IDs) are schematic diagrams that help process engineers understand the arrangement of piping, instrumentation, equipment, and control
systems within plants and industries like oil and gas, chemical manufacturing, power generation, and water treatment. They serve as comprehensive blueprints for process flow and help design, optimize, and oversee complex operations.
Despite their need and importance, it is not easy to create them, thanks to the technical details involved. That’s why many professionals use specialized P&ID software to simplify the process and build accurate and detailed technical diagrams with ease.

Here’s a list of some of the best P&ID tools and software available, each with its own strengths tailored to different engineering environments. Use them to solve key challenges while creating piping and instrumentation diagrams:
1. AutoCAD P&ID

Source: Autodesk
Autodesk’s AutoCAD P&ID has long been a staple in engineering design environments. Built on the robust and most sought-after AutoCAD platform, it comes with intuitive drafting tools and specialized P&ID features, minus the learning curve. This makes AutoCAD extremely popular among P&ID designers.
Some of the key features include:
- User-friendly interface
- Predefined symbol libraries
- Automated error checking feature that helps to eliminate inconsistencies in tag assignments or line numbering.
- Seamless integration with 3D plant model
However, when compared to more modern SaaS-based platforms, AutoCAD P&ID isn’t as ideal for collaborative cloud-based workflows. It demands high system resources, and subscription prices may be high for small teams.
Still, its reliability and compatibility with existing Autodesk ecosystems keep it among the top choices for many engineering teams.
Pricing:
- Full AutoCAD subscription costs $2,095 per year or $260 per month.
- You need a full AutoCAD subscription to access Plant 3D.
2. EdrawMax

EdrawMax is a powerful drawing tool that can be used by both beginners and professionals. It’s used to design flowcharts, graphs, mind maps, and of course, P&ID diagrams. What makes EdrawMax really helpful is that it comes with ready-made templates, so you can simply pick a layout, drag and drop elements, and finish your diagram quickly.
It also works well across different systems—Windows, Mac, Linux, and online through your browser. You can also save your work to cloud storage and share it with others easily.
Main Features:
- Lots of built-in templates
- Works on different devices
- Can export to many file types
- Cloud storage support
- Easy to learn
Pricing:
- Free Online Version
- $99/year or $245 for lifetime use
If you want a simple, flexible, and affordable tool, EdrawMax is a solid choice.
3. Lucidchart

Though not a traditional engineering design tool, Lucidchart deserves a mention for its lightweight, browser-based approach. It’s not designed for heavy industrial use, but for quick sketches, training diagrams, or collaborative planning sessions, as it is easy to use and quick to access.
Its drag-and-drop interface, built-in shape libraries, and real-time team collaboration features make it a favorite for cross-functional teams or education-focused environments where a full-blown CAD tool isn’t necessary.
Main Features:
- Web-based tool, no installation needed
- Simple interface
- Easy sharing and teamwork
- Basic templates included
Pricing:
- Offers a free trial pack with limited features
- Individual plan starts at $9/month when billed annually
- Team plan starts as low as $10/user
If you’re looking for a lightweight tool with a focus on teamwork, Lucidchart is a good option. But it may not be as powerful for complex P&ID designs as some other tools.
4. SmartDraw

SmartDraw is well known P&ID software that is used for making professional diagrams. It’s packed with features and comes with more than 300 high-quality Reichard symbols from major HMI/SCADA manufacturers. With professional symbols for motors, flow meters, pumps, pipes, tanks, valves, sensors, and more, it is built for your custom piping and instrumentation diagrams. There are templates to help you get started, and it supports cloud storage too.
Main Features:
- CAD-like tools
- Many templates and symbols
- Can be used in web browsers
- Offers easy collaboration
- Supports cloud storage
- Great for technical teams
Pricing:
- Individual: $9.95 per month, billed annually
- Team: $8.25 per user, per month, billed annually (3 user minimum)
SmartDraw is great for professionals who work on Windows and want strong features without needing CAD experience.
5. SmartPlant P&ID (Hexagon PPM)
