Finally, you’re going to want to build your own sets with those Legos. Sure there are some really cool sets out there, but probably not quite exactly everything you need. I love Legos, but I confess I am very engineering deficient. There’s no way I could sit down with a bunch of Legos and just build a masterpiece.
Which is why there’s LDraw. LDraw is basically just a CAD program that is designed to help build things out of Lego. Toy around with your design in LDraw and then print out complete building instructions and parts requirements on your laser printer. What could be more cool than that? Oh yeah, it’s completely free!
