Hello, I have a problem with my viewports. I imported a .dwg, which I then deleted as it wasn't what I needed. I then imported a pdf of the drawing I needed and scaled it to the correct size etc. I then went into a sheet layer, and the viewports I had set up before importing anything have gone completely awry. They were set with the correct scale and had annotations etc in, and were within the boundaries of an A1 sheet size. They are now massive, I can't see anything in them and my annotations have disappeared... or the viewport is so big that I can't find them! Please help :(
