On the properties palette for range.
Revit roof plan 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.
When you tried to underlay a floor only doors and windows were visible.
In the project browser open a plan view.
Use the underlay parameters on the properties palette to set an underlay.
How do you make roof lines visible in floor plans revit 1.
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.
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.
You set an underlay by specifying a level.
The slice of the model between that level and the next level up displays.
Once i do this my roof element become visible in the ground floor plan.
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.
Base level select the level you want to underlay.
Three of the underlay options current level level above and level below are relative to the current level.
Select the linework tool in the view panel.
This issue occurs because there is an incorrect view range in the main view.
In this example my roof element is at level 1.
Had to crack open revit and play for a while.
Now it s at this point where i could just trace over the perimeter.
I thought i would see what shows on the first floor view.
In the view properties expand the underlay drop down and select the level on which the roof was created to display.
Open the plan view of the level in which you want to see the roof line.
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.
Now the next step is to select the linework tool from the modify tab view panel.
