Create a fog effect on the floorplan that covers element on the level below

momodestro — Sat, 18 Apr 2026 17:11:06 GMT

In the building I have several double volumes and I would like to be able to show in the floorplan above also what happens in the visible part below. I would like to have kind of a fog effect to make the floor below a bit less strong. Image a cafe stretching in two floor, when I have the floorplan of the second floor i want o be able to see also the furniture of the open part of the level below, but less strong, so it is clear which level i am look at. The fog should cover the visible part and not the cut elements of course. Is there a way with graphic override or similar?

Operating system used: Windows 11

Hi,

The way I see it there are two ways: one complicated and one very basic.

Complicated:
Let's say you have two floors - ground and first.
In the first floor, you can edit the floor plan cut plane to show 1 floor below.
You have to make sure all the object on the ground floor also display on the 1st floor (from their individual settings).
Then you can apply a graphic override, only on the 1st floor, that everything that has its home story on the ground floor should be displayed with grey fills, dotted line etc.

Simple:
Just place a 30% or 50% opacity fill on the area you want to be "clouded" over. Judging by your screenshot, you're already seeing the ground floor contents on the first floor plan.

Or you could place a separate view of each storey as a drawing in a layout.

You could apply a Graphic Override to one view (or place a % fill over it) to create the background effect that you wish.

Or you could set that view to use an alternate (thinner) pen set where each pen is thinner than the default pen set - this will give you greater control than a Graphic Override.

Apply this pen set to the actual view or the drawing as you place it on the layout.

Then overlay the two layouts to form the one plan.

Make sure the background of the drawing you place is transparent so you can see the one below.

I would try to avoid using a % fill as you sometimes get PDF display issues, especially if you do not always use the inbuilt publisher.

I would do layered Views in the Layout with the background views using a GO and Pen Set that lightens everything. Using a single View will result in multiple GO if you have multiple upper storeys. It also allows you to use the Display Limit settings to help set what you want to display normally regardless if it is technically on a lower storey. The main issue with this is if you need to export DWGs...

Thank you for the answer,

I do have already part of the ground floor visible without the need of a cut plane.

I would love to have the graphic override to make it as you said but I don't see the criteria "home story". Could you guide me on this please? This would be my preferred option ask I will have also other parts of the building with double volumes and cross storeys visibility!

Thanks

That option is not available on all elements, but on 3D elements (walls, columns, walls, zones etc). Defining element type like that allows you to use the home story criteria in schedule:
