Roof Outlines in Floor Plan

[nsinha73]

I am trying to activate 'underlay' in my FLOOR PLAN to show the outline (OH) of my Roof Above.
But it appears in Grey, but I need to show the outlines in Black and Dashed....

How can I achieve this?
Thanks guys

Use the LINEWORK tool to apply dashed lines to the roof edges. You can then turn the underlay off, the lines will remain.
