The Lego-like program of choice for less powerful computers
Pros & Cons:
BlockCAD is unofficial 'Lego-like' freeware. So the program is completely free from advertising material. BlockCAD has been in development since 1998 when the Swedish programmer built it for his own children. Unsurprisingly, it has a less up-to-date look and feel than the commercially backed LEGO Digital Designer and a slightly less extensive choice of building blocks and joins.
Nevertheless, BlockCAD has a stimulating set of building options (you can save your work) and the interface is fairly intuitive to use despite a relative lack of text. There are plenty of hotkeys and a schematic user manual is provided, but expect a learning curve. You can display your work against any background image file of your choice.
All in all, BlockCAD is a remarkable individual achievement and may be the Lego-like program of choice for less powerful computers.
