Before I start, enormous thanks to Binvox (http://www.cs.prince...du/~min/binvox/) for their incredibly helpful program.
AutoBuilder automatically takes any Binvox supported 3D model (OBJ, OFF, DXF, PLY, VRML, or STL) and builds it in Minecraft. Because the turtle uses lots of resources, it will return to the ground every time it needs to refill.
It's still a beta program, so feel free to edit the code if you think you could make it faster. You are free to redistribute this as long as you credit both me (pokemonmegaman) and Binvox for their work.
Also, here is a tutorial video (skip to 7:39 if you just want to see a time lapse build):
Thanks for checking out my program!
