Yes, I love Google Sketchup, I am not ashamed of it either, it is so incredibly useful and it's so incredibly free.
I've used it for a few years now, mostly for planning aquarium setups and building aquarium stands. Here is the most awesome part of Sketchup - pulling dimensions, and creating your cut sheets (Someone needs to automate this).
And that's it! 4 Sheets!
Now I have to figure out where I'm going to build this darn thing. I've got a low-ceiling basement with a circular saw, router, and a drill...
I think I might need some new tools...
Stay tuned! I'll be cutting up some wood next!
