I made a layout view to incorporate into my Sheet Set Manager. I labeled this view accordingly so I could easily find it and label it on SSM. I then did a bunch of work on the drawing (new lines, new layers, and new styles). I then accidentelly double clicked on that view in SSM. It took me to the place where I had place where I had made the viewport, cool, but then it took me back in time, before I had accomplished all of my work . All of my new lines, layers, and styles have gone out the window, how do I get them back?? Thank you.
PS I apologize if this has been answered in previous post.
