Hi,
My co-worker and I have both experienced the disappearing or changing scale of a viewport in both AutoCAD and AutoCAD light when we have recieved titleblocks/drawings from other people. We go to change scale in one viewport and in the other viewports the image disappears or changes scale. You then try to fix that one and another changes. We tried locking the viewport, but that doesn't help. Please offer any ideas - I have a feeling it's a setting or some simple command we don't know about.
Thanks!
Stephanie
