re: SketchUp alternative for Linux users

Sketchup is platform agnostic. It runs on PCs, MACs and Linux. I’ve used it on all three platforms and for all intents and purposes, it’s virtually identical. Having said all that, it drives me nuts when I’m totally focused on a design and get sidetracked trying to figure out how to make the software do something. So, even with years of experience using a computer as a design aid, my best work happens when I put a clean sheet of paper on the drawing board, sharpen my pencil, put on some Mozart, and get lost in my own head!
