How do I get rid of dash lines in sloping roof slab?

[fvarela]

I have used Revit’s floor editing tools to slope the roof slab. It results in some annoying dashed slope lines, which I used the “Invisible line” linetype tool to get rid of, and they disappear from the view, but they still plot. Is there any other view setting to get rid of dash lines in sloping roof slabs? I don't want my roof plan to look like an arch plan.
Is there any way to make “Invisible lines” stick when plotting?

Please see attached word doc with screen captures to better see what I'm talking about.

Thank you,
