How do I make a block generator, that generates blocks in Lighting?

I'm not the best scripter, so I dont have a platform for this, but the basic idea, is a script in Workspace/serverscriptservice that finds a block in Lighting and generates each block anywhere in a sppecific location, just like the Quarry by Dummiez. Thanks for helping. EDIT: Heres some code I know

game. Lighting. BLOX: clone()
.....
BLOX.Vector3.new: X:1 Y:1 Z:1

Bad scripting alert.

Learn CFrame a Vector3() just as duckwit said. (Hello once again duck I will see you at SB I would say..) Second go to this link to find a bit more about vector3 and Terrain Generation http://wiki.roblox.com/index.php?title=Terrain_Generation Just click the link above. :)
