An software that can create 3D brick models. AnkerCAD is a freeware software for building virtual models with bricks ('AnkerSteine'). With AnkerCAD 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 impactful, and there is a minimum of text involved, to make it easier for kids,

AnkerCAD is freeware, but if you really like the program, I would be happy if you send me a piece of (real) Lego - yes, I'd prefer Lego, but of course you may send me an Anker-stone instead, if you really want to, and maybe a postcard from your home town. My mail adress can be found in the About... box in the program.

The license of this software is Freeware, you can free download and free use this graphing software.
