My experience with AutoCAD goes all the way back to the DOS versions, but it has been off and on over the years. One feature I missed out on during one of those “off” periods is Dynamic Blocks, introduced in AutoCAD 2006. I just started using Dynamic Blocks recently and found that they can be a huge time-saver. Dynamic Blocks can replace tasks usually accomplished with exploding, rotating, moving, arraying, and scaling with simple mouse clicks. In addition, blocks can be nested within Dynamic Blocks, allowing one to create an array of blocks just by clicking and dragging.
