Awesome, CAD for LEGOs!

ok i know it's been around for ages apparently... but man that's awesome

anybody do a hard drive cage in the "technic" rivit oriented pieces yet? :)

highlights:

• it actually "knows" when you put two technic "i-beams" together on a rivet pivot point... it'll rotate them in 3D so you can line things up with true geometry!
• it adds up the whole parts list and gives you a total price to physically manifest your creation <nifty>
• people can & are publishing their custom designs
• it copies multi-part "bundles" and flips/rotates them easily to construct symmetric objects quickly
