Showing Concrete Core of the wall only

Sometimes, in slab plan, for instance, we want to show the concrete core of the walls only. Typically, you can either show or hide the whole wall, not the finish layers.

Here is one way I have come across that is not perfect, but it does the job!

1- Here we have a sample, with concrete walls, metal walls, and finishes…

2- In Visibility/Graphics Go to Filters. Let’s add a filter, we are going to define what this will filter for us next.

3- Under Categories select Parts, Filter by Material that does not equal to the concrete.
(here you can also filter by Construction, Core and Finish to get the same result)

Here is a little mini Revit session:Try to organize your Materials early on. It makes it much easier if you only have one Concrete material, in this case for example, so it can be filtered out or rendered, or changed easier. I have seen projects with multiple kind of the same material (i.e. something was imported from another project, and project ended up carrying multiple materials for the same thing… Try to avoid that!

4- Let’s now add this filter to the project.

5- Uncheck visibility, this will turn off the visibility for all layers that do not equal concrete – meaning all you see IS concrete.

6- Now, select all the walls in the view, and click on “Modify/Walls” – in the Create section click on the “create parts” icon. For THIS VIEW ONLY, this would take all the layers of your walls apart.

7- In Properties section, and under Graphics, change Part visibility to Show Parts.

8- It’s done!

Notice these walls contain all the layers in all other views.

So… I said this method is not perfect, as you create parts to the walls, the joint feature does not work since we are asking revit to show us the parts as if you are using it for fabrication. So each wall WILL have the start and end. I would love to find a way to create a smooth joints, but I have not been successful. If you know a way, let me know!


Using “Filter” for quality control

This is a nice little trick you can use to double check your work visually. Filters in Revit have so many different applications, but In this example, I am using Filter to color code different doors based on their fire rating, for visual inspection throughout the project.

Let’s take a look at a portion of the plan and compare that with the end result:

Go to View> Filter

I created a Filter and called it Door (90 Min.), and so on for all the other rated doors in the project.

Then go to your Visibility/Graphic window, then Filter Tap, and here you can now add these filters into your View (or View Template). Then assign a different color for each Filter. Make sure “visibility” boxes are checked.


This makes it much easier to identify the correct door rating instead of checking through door schedule!
