The cropping of annotations MUST be handled differently for revision clouds. It is a complete PITA to have to watch for disappearing clouds and manipulate them so they will not disappear.
Could you elaborate? Or provide a screen shot? I haven't encountered this problem.
It happens most easily when you have dependent views. As in an overall floor plan with dependent views to break out smaller areas that will fit on a sheet. e.g. a, b & c. When the clouding crosses over into the next area, the whole cloud disappears. It would be a whole lot easier if it was just truncated.
Here's the annoying thing I think you're getting at.
Here's a Rev Cloud. Almost the ENTIRE Rev Cloud is within the Crop View boundry. And there's just a tiny Annotation Crop boundry.
But when you move the crop boundry ever so slightly...
That is annoying. My only advice is to play around with the Annotation Crop Boundry.
