While walking around the booths at the AIA 2009 Convention, I stopped by Google, who are not only presenting Sketchup 7 but also showing architects how to market their firms using AdWords and YouTube.
Also, they have a very good discount for those of you who want to buy Google Sketchup Pro 7: a $100 off (retails at $495).
So, if you were looking to buy the latest version of one of the most easy (yet powerful) modeling tools just head to their store and use promo code SUAIA9, valid until May 15, 2009 on single-user licenses only.
You can also download the basic version for free.
