Sketch Up v ify sketches

I know most of my fellow sufferers already have the sketch up package. I was looking at the demo on-line yesterday and it looks really great. You can get a free download but only for 8 hours. I only wonder if 8 hours is long enough to produce anything? I question as to whether my sketches are up to the required standard? My site contains mostly veg rather than buildings, so I am not sure how useful this package would be, as it seems to work better with geometric shapes!! I don't knowwhether I could convert any of these? Watch this space!
