Decompile that bad boy and see what you can come up with! If I made this map as a model in rhino, I could export elevation drawings from it and add lineweight in illustrator! I could even make section drawings of the map.
It's funny, I sometimes use hammer to make drawings for school. I just change it to black on white and make everything black by grouping it and "hiding it" and then editing it's color to black. It's like "layers" in halflife. Maybe I should write a tutorial.
Here's an image I got from a 3d model, couldn't open it large bc I don't currently have illustrator.
Edit: ohh, hahaha you made them look like they are hanging on the wall. yea!
