"GrabCAD is the largest online community of professional engineers, designers, manufacturers, and STEM students on the planet. We help you create amazing products easier.
Today, the GrabCAD Community has almost 6 million members sharing CAD files and professional tips, participating in design challenges, or downloading free CAD models from our online library of over 4 million free files. The Community is a place for thought-leadership and education for the latest in engineering, design, and manufacturing, a place where professionals can show off their skills and encourage others to learn the same.
We also offer two software applications (with more under development): GrabCAD Workbench and GrabCAD Print.
GrabCAD Print is the most complete solution for Stratasys 3D printers available. The intuitive, easy-to-use software allows for simplified preparing, scheduling, monitoring, and reporting of print jobs. With the ability to read CAD files natively, GrabCAD Print offers an efficient workflow that streamlines job management in shared office and model shop environments using Stratasys FDM and Polyjet printers.
GrabCAD Workbench manages the complexity of engineering projects with private, secure collaboration, CAD file management, and version control built in." (https://resources.grabcad.com/company/)
