I have always used the Cut Line tool in the Documentation palette. In the past it always acted like a trim line, based on the trim plane concept.
Now it appears that the Cut Line tool creates a masking block. The masking tool is fine, once you learn how to control it, but the problem is a printing issue. I ran test plots yesterday of my project and there are black spaces all over the place, where ever there is a cut line.
Am I missing some sort of setting to make the visible mask disappear?
