Hi! I am new to ST. I want to thank all of you for the great tools and all the comaderie displayed by the denizens of Simtropolis. I do have one question: I am trying to learn to use the tunneling (Hole Digger) tools, and I have a question: has anyone tried using them on diagonals? And if so, how does one do it? Thanks again for all the great tools and I hope to be a contributor to this great site!
