How to show overhead wall with overhead windows

[Paul King]

Hi - I cannot seem to find a way to show in plan the presence of a wall overhead containing clerestory glazing, and to have both windows and wall display as dashed lines
With various combinations of window & wall projection methods I can get either one or the other to display with dashed overhead lines, but not both.

I don't want to manually override the wall cut lines to make them dashed in plan, as this then affects the view in section

How can windows AND wall be displayed as overhead projection simultaneously , but only in plan view?
