Anyone worked with this program? I just got a 2 hour showing of this today. This may not replace acad but it's damn sure impressive. 3d rendering and runs fine on a 1.6 mhz 512 ram and 128 meg video. & no, I'm not selling it etc. etc. etc. sketchup.com The libraries are short of needed things and there are some shortcomings as to what I seen today, but still damned impressive. Cost is about 470.00 US Any opinions? experiences? The demo I seen today was being used primarily in doing piping and mechanical. Guess it was designed for architects but seems to go way beyond that.
