ClickUp is a comprehensive project management tool for managing engineering projects and operations, and pretty much every other area of your business.
The platform has ClickUp Mind Maps, which is really cool for mapping out your ideas and figuring out how your projects should flow. Need to get those ideas into a plan? There are hundreds of templates to help you do that fast. ⚡️
This includes ClickUp’s Process Mapping Template. It’s perfect for standardizing your P&ID workflows—whether you’re designing P&ID systems from scratch, running maintenance checks, or improving existing systems.
When it’s brainstorming time for P&ID systems, ClickUp’s Whiteboards are a great space for teamwork. The pen, sticky note, and shape tools make it easy to design flowcharts and sketch diagrams. You can also embed ClickUp Mind Maps, ClickUp Docs, images, links, and files inside the Whiteboard for a better overview of your ideas and resources.
Got an idea during the brainstorming session that needs to be executed? Convert the text into a task right inside ClickUp Whiteboards. Thanks to the task management features, you can easily assign these tasks to team members, add a deadline, and attach relevant details and files needed to get the job done.
This way, everyone is on the same page and nothing slips through the cracks.
📮ClickUp Insight: 11% of our respondents leverage AI primarily for brainstorming and ideation. But what happens to these brilliant ideas afterward? This is where you need an AI-powered whiteboard, like ClickUp Whiteboards, which helps you instantly turn ideas from the brainstorming session into tasks.
And if you can’t quite explain a concept, simply ask the AI image generator to create a visual based on your prompt. It’s the everything app for work that enables you to ideate, visualize, and execute faster!

Lucidchart is a flowchart software that turns your complex ideas, plans, and processes into simple and colorful diagrams. It has multiple shape and symbol libraries for designing flowcharts, process maps, P&ID diagrams, mind maps, wireframes, and affinity diagrams.
If you don’t want to build these designs from scratch, there are over 900 P&ID and engineering templates to help you get started. You can also import and edit existing files from Microsoft Visio, Gliffy, Draw.io, and OmniGraffle.

EdrawMax is an online diagramming tool that lets you create over 280 diagram types, including P&ID diagrams, flowcharts, mind maps, wireframes, floor plans, and electrical drawings.
With EdrawMax, you have access to over 1,500 native templates (covering engineering, UI & UX, product management, and business) and 20,000 more via its community template library.

M4 Plant is a plant design software for 2D and 3D factory and plant designs of all sizes. It has 17 modules including piping isometrics, piping & instrumentation diagrams, steel structure, HVAC ducting, and electrical routing.
A key M4 Plant feature is generating bills of materials (BOMs), part lists, and line lists at any stage of your design. This is very helpful for estimating costs and ensuring that all necessary materials and components are accounted for throughout the project. ✔️

SmartDraw is another user-friendly diagramming tool for creating flowcharts, mind maps, piping designs, wireframes, space plans, and more. It has dedicated symbol libraries for each of these designs. So for your piping and instrumentation diagrams, you can choose from over 300 symbols to produce professional designs.
A handy feature is installing SmartDraw Apps inside Google Workspace, Microsoft Teams, Confluence, Jira, and Trello, to collaborate on your diagrams without leaving these apps. And when your designs are ready, you can share a link or export them as PDF, PNG, or SVG files.

Procad P&ID is specialized P&ID software for 2D and 3D piping and plant designs. It has an extensive library of standardized symbols for motors, valves, heat exchangers, and more, with options to customize these symbols for your specific needs. ?️
Your Procad drawings are saved as DWG files, the file format supported by popular CAD apps like AutoCAD. This way, it’s easy to share them with external stakeholders who can view and edit them in their desired software. When you get the files back, Procad scans and flags any changes, giving you the option to accept or discard them.
If you already have AutoCAD software, you’ll get 25% off:

Sphera offers services and software to improve safety and Environmental, Social, and Governance (ESG) performance in the workplace. Their risk and sustainability management platform, SpheraCloud, has a P&ID module for streamlining isolation planning with lockout/tagout procedures.
Upload a PDF file of your schematics to the platform and mark it with isolation points and rules. This gives your team full visibility into equipment status and potential risk areas. ?

IronCAD isn’t specifically a P&ID software, but it’s great for 2D and 3D CAD product designs. It’s handy when you need to tackle P&ID tasks along with your CAD design work. ?♂️
Unlike most CAD software, IronCAD has a TriBall tool that makes moving and manipulating objects super easy and fast. You can also boost IronCAD’s capabilities with add-ons for stress analysis, motion analysis, and creating realistic 3D model renderings.

Visual Paradigm is a system modeling and diagramming software for creating visual designs. Build these designs from scratch or choose from the over 800 flowchart, process flow diagram (PFD), P&ID, and wireframe templates to jumpstart your work.
Depending on your business needs, you can use Visual Paradigm in the cloud, on-premise, or in a hybrid setup.

AutoCAD, a CAD design software by Autodesk, is similar to IronCAD. But AutoCAD takes it a step further with AutoCAD Plant 3D, which combines its CAD functionality with P&ID and 3D piping features.
If you only need 2D P&ID software that’s easy on the wallet, AutoCAD LT has got you covered. AutoCAD and AutoCAD LT work on Windows, MacOS, and Linux devices. And when you purchase either version, you get access to AutoCAD’s web and mobile apps (AutoCAD Web).
Each of these P&ID software options has unique features to enhance your diagramming process and designs. Evaluate each of them carefully so you can pick the P&ID software that perfectly matches your process industry workflow and preferences.
