I have created a drawing which is opening funny. Everytime I open this drawing all of my datum planes are displayed. All of my layers are off and the status saved. Even the display datums button is off. I can turn the display datums button on and off and redraw but they won't go away. And the wierdest thing is if I go into the layers and turn a layer on and save the status they will disappear. I then close, erase and open again and they come right back. It is almost like I have to change the layer status before Pro E will read it. Does anyone have any suggestions?
