This is a great application. Sketchup is by far the easiest to use 3D modeling software on the market, not that I’ve had that much experience with other similar products, but after viewing the tutorial I was able to build a simple house complete with people and pets in under 10 minutes. And it was fun!
Google announced the purchase today and I’m trying to figure out the relationship and how the acquisition will help Google. There’s a plugin for Google Earth available, but that seems relatively minor in the grand scheme.
