Base level select the level you want to underlay.
Revit roof plan underlay.
Open the plan view of the level in which you want to see the roof line.
In the project browser open a plan view.
On the properties palette for range.
I highlighted the roof lines that are the underlay.
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.
You set an underlay by specifying a level.
Had to crack open revit and play for a while.
Now the next step is to select the linework tool from the modify tab view panel.
If the view range intersects the geometry of a level in your main view that level cannot be used as an underlay in the main view.
In the main floor level the bottom of the primary range is set to main floor with an offset of 1.
All other choices are absolute.
How do you make roof lines visible in floor plans revit 1.
Select the linework tool in the view panel.
In the view properties expand the underlay drop down and select the level on which the roof was created to display.
In this example my roof element is at level 1.
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.
The slice of the model between that level and the next level up displays.
Then select the line style you want to represent the roof overhang in the view.
Three of the underlay options current level level above and level below are relative to the current level.
When you tried to underlay a floor only doors and windows were visible.
At first i thought the problem was that i had underlaid the first floor on the lower level revit didn t like underlaying a floor above but i ve done that on other projects and it worked as expected.
Use the underlay parameters on the properties palette to set an underlay.
Now it s at this point where i could just trace over the perimeter.
Once i do this my roof element become visible in the ground floor plan.
