It works with many CAD programs. It's similar to git, but for CAD files.

Before starting work for the day, you use the GrabCAD software to get the latest copy of your project.

You do some stuff and use the software to commit your changes.

I only ever used it as a single user, but it tracks every change you make to every file and who made those changes. The best part is the online dashboard which lets you view and comment on 3D CAD files online even when you don't have any cad software installed on the computer.
