Don't ask Santa Claus for a box of Lego at this end of the year! :)

Create your object in the official Lego Designer http://ldd.lego.com (free)
Export it as ".ldr" format

Launch LeoCAD http://www.leocad.org (free)
Open your ".ldr" object

Save as Waterfront ".OBJ" format

Import it inside Moi3D with _ImportOBJ by Max SMirnov

et voilà :)

PS You can win a Step in create Lego Object directly in Leo Cad! ;)



The same in SketchUp! ;)



Of course, it's the real brick!!!
