The first step is to go to the elevation that will be used to display the object through the walls.
Revit floors showing through walls.
If you are in the level 3 plan view then the base constraint will be set to level 3.
Given some walls that go from level 1 to level 2 and a floor at level 2 i have a project where these walls below show thru the floors in plan.
The top offset will default to the last used value e g.
All you need to create a revit floor is a level for it to reference you do not need revit walls or columns beams etc top support the floor element.
This isn t an underlay nor is it a transparent floor.
As seen above this behavior does not occur in the wireframe visual style when using a transparent background for solid fill patterns elements below the fill will show through.
Then change your visual style to wireframe.
That sounds like a nasty little endless loop.
What should i do if my revit does not show any ground floor level or bottom reference level in house designing.
When placing a filled region you may find that elements with a surface pattern specified show through the filled region when the background is set to transparent and the pattern is set to solid.
To create a revit floor access the architecture menu the build panel and then select floor.
If i start a new project from the revit template i don t get this behavior.
In plan view click view menu view properties.
If you are in a level 1 view and set the top offset to level 2 the next.
Just for future reference when placing walls revit will default the base constraint to the level of the view you are in.
As soon as you hit the floor icon you will be presented with sub options architectural.
