What are the benefits of getting all this software in one collection?

In addition to offering great price value, the Product Design & Manufacturing Collection enables you to take your designs from concept to production with workflows for design, advanced simulation, 5-axis CAM, nesting, and factory layout. You also get access to the full breadth of AutoCAD, along with new cloud-based technologies like Fusion 360. Because the collection provides both the latest and previous versions of included products, it supports compatibility with others on your team. And, you manage only one collection license rather than multiple product licenses.
