wow... that is an extremely powerful tool.
I'm still stuck back in the CS4 dark ages, but I would love to mess with that.
Those nay-sayers probably didn't watch the video, but I would be very surprised of there is anything comparable to the power in this offering, that has already been out there for any length of time, if at all.
I love how you draw & it's already in the perspective plane as you draw, and then you can drag, IN PERSPECTIVE, so making multiple repeats of something at varying distances, using the same vanishing point becomes as easy as copy & paste!!
First thing I've seen in CS5 to make me want it!
