How to Split and Join Walls with Different Types in Revit

To address this area where we have an interior wall and an exterior wall at the same location, we'll need to split this wall so that we can maintain the interior Wall type here and the exterior Wall type on this side. Since this wall is set up to have the Wall center line as its location line, we should expect it to grow equally on either side. The other thing I want to look at here is which face of it is the exterior.

And so I can see here with this toggle, which always represents the exterior face of the Wall, it's on the interior side. So I'm going to change that so that when I change the Wall type here, it'll be facing the exterior. So there's one less thing I'd have to do after the fact.

The first thing we want to do is split, and we want to make sure that we have this Delete Inner Segment unchecked here. Because we're not trying to delete the segment, we're just trying to break the Wall into two pieces. And then I'll go in, and what I want to do here is I want to just split the Wall approximately at the face like you see there.

And you'll notice as you move your mouse through, it kind of locks in at these points and it should be pretty close to that exterior side. Now with this Wall selected here, what I could do is I can change that Wall type to the Exterior Brick on Metal Stud. And this is a good time to point out that as we use different Wall types, we'll have this Most Recently Used Types option to where I can go in and I can actually just pick the one that I've used previously.

Now seeing that it grew equally on both sides there, we know that we need to make an adjustment because we no longer have a Wall aligning here. To do that, we're going to use the Align tool. If I were to go to my Modify tab and look for Align**, then I should easily be able to align the faces of these Walls together.

So with the Align tool selected, I'll pick the face of the Wall to the face of the Wall and then they'll line up. We'll address this joint condition after we adjust the other side first. We'll go through the same process.

I'll use Split**, and the keyboard shortcut is SL for those of you guys that like keyboard shortcuts. And I'll do the same thing. I'll run it along the edge here to split so that I have two pieces here.

And I want to double-check to make sure that it's facing on the exterior, and it is. Now I just need to change the Wall type to Brick on Metal Stud and use the Align tool, with the keyboard shortcut AL**, to then align it in place. Now the next step here is to use our Wall Joins tool to join these three Walls in a condition that we're looking to have them joined to.

To do that, the first thing I want to do is change my Detail Level from Coarse to Medium**, and that allows me to see all the different layers that make up these Walls. It may also help to switch to Thin Lines so that you can see all the layers without the heavy line weights getting in the way. From the Modify tab, I'm going to go to my Wall Joins tool and then I'll hover over this intersection.

You can see it creates a big box there. And I'll go ahead and select that Wall Join**. Now we have these options for Previous and Next, and so what I'll do is I'll click until we have a Join condition that works for our project.

And you can see how it'll cycle through all of these different options until we find the one that we're looking for. The condition you see here is going to work for our project. We'll go ahead and do the same thing on the other side just by clicking Next, and then you can see we can go through all the different Join options until we find one that works.

And this is the same condition that we had on the other side, and so we'll go with that.
