Would someone be able to tell me how to scratch input a field from pictures or whatever? I want to put my backyard into G2 to practice flying in the dimensions that I have here. I have about a 4 acre field with some trees lining 3 edges, and on the 2nd level down of a large "terrace" for lack of a better description. If anyone has an idea of how to do this I would appreciate hearing. I could supply some pictures if you want to see better what I am talking about. Thanks in advance.
