That would be good if they all saved at once. I don't know what happened this morning. I had 7 views in a drawing. Each parts had a layer called BORDER. I turned this off in the drawing and one remained although it was in the list of hidden layers. Once I cleared memory and reopened the drawing, all was good.
Most times, I only use layers for drawings. And inevitably, it is why I need to use hidden layers by view rather than the drawing, simply because one lousy view needs a layer shown and hidden in all the others. It is an evil dance. This is also why I do not use all those layers in templates. I have very specific purposes for layers.
