Cadimage Coverings Pen Settings
Select the covering and open the Selection Settings. Under the Cladding tab go to the view attributes and set the background pen to 0 Transparent. This can be repeated for edge conditions pen settings to create “transparent” flashing, gutters, ridge and barge elements as well.
The result is a fully transparent roof element in floor plan view. This will allow you to view elements below the covering in model space as well as on the sheet with multiple layered plans.
