11 Best P&ID Software Tools for Process Design Engineers in 2025

Piping and Instrumentation Diagrams (P&IDs) are very important in industrial engineering because they show how processes run, how control instrumentation works, and how equipment is set up. These diagrams are very useful for designing, operating, analyzing safety, and planning maintenance for plants that process oil and gas, chemicals, power, and water.

Making P&IDs by hand is boring and easy to mess up. Luckily, new P&ID software solutions make this job easier by having smart sketching functions, symbol libraries, tools for working together, and the ability to work with 3D design software.

This is an in-depth description to the 11 best P&ID software platforms, each of which has its own set of features for professionals, project engineers, and EPC teams.

What is the best software to draw P&ID?

For professional industrial-grade P&IDs, AutoCAD Plant 3D (AutoCAD P&ID) is widely regarded as the top choice, offering built‑in industry‑standard symbol libraries and 2D/3D integration.

Can SolidWorks do P&ID drawings?

Yes. SolidWorks P&ID, part of the SolidWorks Utilities, uses a structured XML-based format (.xml) to define equipment, piping, and instrumentation for routing and downstream assembly creation.

How to create a P&ID drawing?

Start by listing required elements like equipment, instruments, valves, and piping. Then use shape libraries in a P&ID-capable tool (e.g., Lucidchart, AutoCAD Plant 3D) to drag-and-drop symbols, connect flows, annotate tags, and validate against process specifications.

Can I draw P&ID in AutoCAD?

Absolutely. you can draw P&IDs using AutoCAD Plant 3D, which is included with standard AutoCAD subscriptions, offering symbol libraries, drafting tools, and error checking specific to P&ID workflows

Can I draw P&ID in Revit?

Revit supports P&ID workflows via the Revit P&ID Modeler, which enables efficient piping design and annotation using standard P&ID conventions .

Which AutoCAD is best for piping?

AutoCAD Plant 3D, as a specialized toolset included with AutoCAD, is the best choice for piping and instrumentation design due to its symbolic libraries, specification-driven piping tools, and integration with 3D plant models .

Is Revit good for piping?

Revit, with the P&ID Modeler plug-in, supports schematic design and documentation for piping systems. However, it’s best suited for building services and HVAC rather than heavy industrial piping applications.

Is AutoCAD Plant 3D better than AutoCAD LT?

Yes. AutoCAD Plant 3D includes the Plant 3D toolset for advanced piping and instrumentation needs (like symbol libraries and 3D modeling), while AutoCAD LT offers only basic 2D drafting, missing specialized P&ID features.
