Comment on SketchUp

This superb application is a essential visualisation tool which only needs a few basic concepts and a bit of lateral thinking to learn. I managed to make a scale model of a space I was working on in my first attempt. Later, I was importing images and textures and exporting animations of concepts. Mind bogglingly great for a free app. I think my only quibble is if pan, tilt and walk were just one tool (modified by keystrokes) rather than different tools.
