CAD Block, or blockcad is not a full CAD program but a free ware version that you can use to build virtual models with lego like blocks. You are able to save your models, or pictures of them in .bmp or .jpg formats, and reuse a model as a part in another model. While the software is very basic, it will allow you to build virtually in a similar way that you would build lego. You can use your mouse
. or keyboard to build and move the blocks, and with minimal text commands, it is a great program for children. To find out more, visit this website, http://web.telia.com/~u16122508/proglego.htm
