Can a "GMAX heavy" type have a look at these pics? I need to figure out how to eliminate the "seam".http://forums.avsim.net/user_files/128681.jpghttp://forums.avsim.net/user_files/128665.jpgThanks in advance!Robert

Looks like you have a triangle instead of a quardilateral. If I am correct, you can solve the problem by selecting and deleting the edge opposite the 90 degree angle of that triangle. The, switch to polygon select mode (the red square, click it), and clicke the "create" button. Then going in a counter clockwise direction, click each of the vertices, with the last vertex you click being the one that you first clicked.I really hope that helped

Ramon,Thanks for the input. The problem is with the poly having a very slight twist to it, I did some vertex surgery that looks like it will be successful. I'll let ya know...Robert
