Hi, my name is Forrest and i really enjoy playing/DMing D&D games, but always had a fascination to maps. I currently go to school at the local college for Mechanical Engineering and when I should be studying I'm usually making maps in my notebooks. I found Cartographers Guild through reddit where i spend most of my limited free time.

While I'm introducing myself I had 2 questions that i thought might be quickly answered.
1) How do you open .gtx files on Photoshop CS6? I was following the town map tutorial found in the pdf tutorial section here and couldn't figure out how to open it.
2)Are there any other town map tutorials for town maps on here, I've searched slightly but haven't found exactly what i was looking for. I was looking for something that would show how to make up close city maps, almost like city blocks for a fantasy map.
