BlockCAD is a freeware program for building virtual models with Lego-like bricks.
You can save your models, or save pictures of them (.bmp, .jpg), even reuse a complete model as a part in another model.
Everything can be controlled with the mouse, but it's also possible to use the keyboard for most of the commands, making 'routine building' more effective, and there is a minimum of text involved, to make it easier for kids,
BlockCAD is not a full CAD program, the pieces can only be placed 'studs up', and rotated in steps of 90 degrees. It is impossible to draw pieces that are partly inside other parts, which excludes almost all of the Lego Technic line, but there's still a lot of fun to be had with it.
BlockCAD is freeware, but if you really like the program, I would be happy if you send me a piece of (real) Lego, and maybe a postcard from your home town. My mail adress can be found in the About... box in the program.
If you don't have any LEGO, or don't want to part with any of your bricks you can send me some money instead ($1, $10, whatever you think it's worth) through my PayPal account by clicking the button here:
BlockCAD was started in the summer of 1998, when I saw a demo of a commercial brick building program (whose name escapes me for the moment), and I thought: "I can do that too!". So I did.
The Lego 'purists' should be wary, because I am not strictly following the Lego look, just doing something for fun. Some parts look like Lego, some are from the Swedish clone, Byggis, and some are pure fantasy.
