you mean google sketch-up????
You betcha. I love Sketchup. Lots of Rubys(plugins) and renderers. Easy to draw complex models in lots of different styles. PLUS..the 3d Warehouse, where you can find literally MILLIONS of models of almost anything from screws to machine guns.
At a click of the mouse, you can download them and insert them into your own model. Where do you think I got the toilet and tub?
Oh,and not to mention.........its FREE!!
Speaking of free, there is a killer renderer for
sketchup called Kerkythea. Dang...unbelievable. Although it takes a much more updated computer than mine. Frankly, I'm almost ready to build a new graphics computer with an
Intel i7 quad processor and the unbelievable Nirvada Quadro graphics card. Nirvada is building entire platforms for high end engineering/chemical/physics and 3d movie computers from these cards. Up to four of them on one special motherboard. Holy moly. You can't believe what their doing with these. Do a search on CUDA, which is an entire graphics system.
