The New tab in AutoCAD 2015 displays the Create page by default. From there you can slide to the Learn page by clicking on Learn at the left or bottom of the page.
The Learn page provides tools to help you learn AutoCAD 2015. It’s divided into three columns: What’s New, Getting Started Videos, and Tip/Online Resources. Check out the many links to videos, the Hitchhiker's guide to AutoCAD, and a free 30-day trial to Lynda.com where you'll find additional learning content.
