I have an idea for layouts, but it is may already in your mind.
I tested more and I realized there is no need to use the "Create Plan View" command.
So when I set layouts-plan views on papers and I set stories there (double click on small door icon) works everything fine, viewports are keeping the views of the named levels.
However the problem is with the annotation and dimension stuff. For example when I have 5 level building and each level has 3-4 line of dimension on each side of the building and I activate the planview, I can see nothing because dimension will cover each other, however whith an extra clipping plane (bottom of the current level) we could hide the dimensions below on the certain levels.
What if we want to see the levels below? We also can use the Create plan view command.
