The fact that it's free and helps build a big community of CAD Designers makes it an awesome software . It gives good connectivity with people working on a single project even if they are from different parts of the world . The feature that allows the user to roll back to a previous version is just amazing, now we can recover a previous version of the design and work on it if needed. There are options to share your designs with vendors from anywhere in the world so that they can review your design and give feedback about the cost of manufacturing and so on. Top secret design projects can be worked on using this software as it's completely safe. It is one of a kind and has so many features that helps design engineers with their work.

GrabCAD Library is a great resource for finding not only specific products ready for 3D print or CAD software download, but it is such a big database that it is also nice to be able to view and browse files for the CAD files to get ideas from an opensource community to make your own 3D model.

Very easy to use, love the multitude of options Available.
