Simple interface

Some technical drawing tools are unwieldy and time-consuming. With Lucidchart, drawing lines and shapes is seamless—just drag and drop onto the canvas. Are you creating an engineering diagram that requires objects measured to scale? Consult our panel that displays exact shape dimensions as you resize.

Better than Visio

For years, Microsoft Visio was considered the standard solution for certain technical drawings. But now Lucidchart offers a tempting alternative to traditional diagramming software. Not only can users import old Visio files for viewing and editing, they can export any Lucidchart document to .vdx format.

Wide range of options

Get started with one of our hundreds of pre-built templates. This resource will save time as you build technical diagrams like electrical schematics, block diagrams, circuit diagrams, P&ID diagrams, network diagrams, and more. If you create a particularly compelling diagram, feel free to save that as a template as well.

World-class collaboration

Whether you’re working with a team of professionals or a group of students, Lucidchart is the ideal tool for visual collaboration. It’s easy to chat, comment, edit, or view your documents, no matter how many other people are accessing the diagram. Try it for free!
