Process and electrical drawings are mostly symbols and the lines between them. EdrawMax carries symbol libraries for piping, instrumentation and circuits, and P&ID work follows the ISA S5.1 identification standard that plant engineers already use.
More than 500 ready templates cover both areas, such as a membrane cleaning unit for P&IDs or a basic parallel circuit. They give you a layout to adapt rather than a blank canvas.
If the library lacks a valve or sensor you need, build your own symbol library and drag your parts in like any built-in shape. Circuit work gets connectivity tools that create line jumps and connected wires automatically.
Reviewers rarely own the same software, so export to PDF, PNG, JPG, Word, Excel, PowerPoint or Visio keeps the drawing readable for them. Visio .vsdx and SVG files import for a drawing you did not start yourself.
The free trial caps general diagrams at 60 shapes, so a real plant drawing needs a paid plan. A bundle with EdrawMind or EdrawProj currently goes up to 50% off if the project also needs a schedule.

Does it follow a P&ID standard?
The P&ID guidance references the ISA S5.1 instrumentation symbols and identification standard.
Can I add my own symbols?
Yes. You can create a custom symbol library and drag your own parts onto the drawing.
Is it a replacement for CAD?
It is a diagramming tool for schematics and process drawings, not a CAD package for dimensioned design.
How many shapes can the free version use?
The free trial limits general diagrams to 60 shapes and specific diagram types to 120.
