Quoting David Roberts
Wow! A very creative use of LDD. Those circles must have a quite a large diameter in real life. I wonder what could be built with them: a space-station or a ferris-wheel or a mono-rail...?
Thanks! Yeah - the diameter i doesn't calculate, but with this circles you come on the end of LDD... open the file if you want to see it ;-) If you look ca.45° degrees from above on it and zoom out => the pieces in the backside dissapear... And yes you could do anything you want with that! a spaceship maybe :) !
