The workflow from Illustrator to Edge Animate and Reflow just got much, much simpler. Before the new CC update, users had to export a .SVG file from Illustrator which could be confusing based on the setting options. Now, all they have to do is copy the drawing from Illustrator to the clipboard, and paste it into Animate and Reflow. The new updates have made this really simple.
The Perspective Grid, which has been around for a while, has been improved dramatically in the latest release of Illustrator CC. So much so, it gets my vote for most improved feature in Illustrator. Why do I like it so much? The objects that are drawn on a perspective grid and the grid itself are now connected. So if you need to change the perspective of your completed drawing, you just change the grid and the whole drawing updates to your new perspective.
