In the view properties expand the underlay drop down and select the level on which the roof was created to display as an underlay.
Revit roof plan underlay.
In other words using a level above as a reference for a lower level.
Use the underlay parameters on the properties palette to set an underlay.
For example you may want to set an underlay for the casework in the kitchen to make it easier to place the light fixtures above.
So i change the underlay parameter you find this is the properties palette to the level where your roof or roof light canopy etc resides.

Select the linework tool in the view panel on the home ribbon.
We recently had a team working on a high rise project and they wanted to use the level 8 plan as an underlay for the level 5 design.
Now it s at this point where i could just trace over the perimeter.
This issue occurs because there is an incorrect view range in the main view.
Once i do this my roof element become visible in the ground floor plan.
If you re experiencing problems displaying elements using the underlay property of a revit view the feature just might be behaving as designed.
In the properties dialog box for the view you want to see the overhang lines in set the underlay drop down to be the level on which the roof was created.
In this example my roof element is at level 1.
In the project browser open a plan view.
When i draw a roof plan i keep the level below on as an underlay which is automatic when opening the roof view.
Create an underlay when you need to understand the relationship of components at different levels for coordination and construction.
But up until i upgraded to revit 2019 i always selected items in the underlay that i didn t want to show up and hid them.
1 st floor no overhang.
Walls doors windows nothing is select able.
