If you have more than one PDF overlay, you might put them on separate layers. Generally speaking in this case, the PDF extents overlap so when i plot different sheets, I would want only a single PDF to be visible.
So, my first thought was to freeze the layers of unwanted PDFs in the viewport. Except, once i did that, nothing happened. So, i guess i have to manually freeze the layer when plotting each sheet? I then can't publish the layouts as the appropriate PDF's won't be visible.
If they were used all at the same scale, that would work. I have 2 at one scale and 3 at other scales. Ironically, the 3 at the larger scale aren't a matchline scenario. But more of a turn of the head to focus on another area of the site.
Thanks for the reply! Good thought about clipping. Had slipped my mind.
