For those new to the world of AutoCAD, as well as those honing longtime skills, an effective resource is the "Beginning AutoCAD 2019 Exercise Workbook" by Cheryl R. Shrock and Steve Heather from Industrial Press Inc. Two new features are included in the 2019 edition, “Drawing Compare” and “Shared Views,” both of which make it easier for colleagues and clients to share and comment upon changes to drawings in real-time.
