I just want to say how much I appreicate the help I've gotten from the Bryce forum. Many times I would have given up if tJohn and others hadn't come to my rescue. Learning the program by myself was difficult for me. I read the manual, but there are things not in the manual, or I get a little lost about where to look for answers or I get confused when I find the answers. The people here really try to help someone with problems. True, you learn by doing, but Bryce, and other programs can be daunting to the newbie and a bitt of guidence goes a long way. Thank you for your help.
