Thanks for the suggestion. However, I'm at a loss. I have two classes that are affected: Plant Material-Tree and Plant Material-Perennial. When going thru visibility, one class at a time, only the ticks came up when got to Perennial. I highlighted everything and clicked on the same class in Obj. Info. the program was churning and the outlines came up. However, when I did the same thing for trees, only the ticks remained. I went back to Perennial visibility and only the ticks were there. Can you suggest someothing else for me to try? Thanks.
