3d Software for Scout Pioneering

There have been a couple of questions recently about the software I use to make the drawings on this site.
The 3d program I use is called SketchUp, it is unbelievably fast and pretty simple to use in comparison to other 3d software. Recently, the company was purchased by Google. You can download a trial version here, this will run for 8 hours of use- enough time for you to learn the software and build some fairly detailed models (a typical drawing for this site will take me about 15 to 20 minutes). To get a feel for how it works, watch the video tutorials before opening it up and building a computer model of your own pioneering project...
