Attached Link: Dancer Xeandra-Lea

I have been trying to make large graphics in Bryce but can't see the bottom part if I change to the larger size. I know there is a 'preview' square at the top left hand side but doesn't always help me. How do you view, add or change the meshes after you resize it large? Or do you use the default size, make your graphic, then resize to the larger size when you are done? Also, when I do this, the background becomes larger but the meshes stay the same size. I am doing something wrong. Can someone please help me with these steps. I have attached a link to one I just did but want the whole graphic larger without just the background (which is black) larger. Hope you know what I mean. Thanks for any help you can give me. BJ
