Join Paul F. Aubin for an in-depth discussion in this video Working with wall layers, part of Revit: Rendering.
- With you creating a model for construction documents or rendering or even for both at the same time, you'll want to probably create your walls pretty early on. Walls are perhaps the most basic element of any building model. In this movie, I'll assume that you're already familiar with the basics of walls and I'm gonna focus instead on just the aspects of modifying the wall that will suit us for generating our renderings. So I'm gonna do a fairly simple example here. What I've got is our office building file that we were looking at in some of the previous movies but I've isolated it to show just the walls here in this particular view.
So, if you look over here on the project browser you can see that there's a view called exterior walls and all the other objects have been hidden. Now to get started, I'm gonna actually create a little piece of wall off to the side. So, the simplest way to do that is to actually select one of my existing walls and here on the modified toolbar I'm gonna use the create similar tool. This is gonna allow me to draw another wall that's basically the same as the one that I have selected. So, I'll just sort of draw a little segment of wall right here and then cancel out of there.
Now I'm gonna select that wall and modify its type. Now I like to do it this way working off to the side because it allows me to experiment a little bit and not have the changes immediately applied to the rest of the model, and in this way if I don't like what I've done I can just discard it and try again. So let's go through the steps. So I've got the wall selected and I'll come over here and click the edit type button. Now that will display the type properties dialog and the very first thing that I want to do is duplicate this wall type. That will create a brand new type that we'll apply only to this wall for the time being.
Now it will suggest a name with the number two at the end and I'm just gonna remove that two and add my own suffix, and I'm gonna put stucco on the end of this wall. Now, the location where we go to manipulate the structure of the wall is actually right here at the top. So we get structure and we'll click the edit button here. And that will display a table of all the existing materials that are in this wall. Now I'm not gonna through all the details of a layered wall structure. We actually cover that in a fair amount of detail in Revit Essential Training so you're welcome to review the movies there if you need to.
What I'm gonna focus on is the vertical structure down here. Now you'll see the first thing that we'll notice is that it's completely grayed out. So, the first thing we need to learn is how do we actually manipulate the vertical structure. So to do that what you actually have to do is click the preview button here. It tells you that the vertical structure is only available in section preview only. So you click preview and then the view type is currently set to floor plan. So, if you click there there's a drop down and when you change this to section, that will make all of these buttons available.
Now, the preview that you see over here is actually interactive. You can drag your wheel to pan, you can roll your wheel to zoom and you can actually control the height of that sample using this sample height parameter right here. Now, it's suggesting a sample height of 20 and in this case, that 20 suits me just fine. So I'm gonna leave that but feel free to change that height in your own workings depending on what you're trying to do. Now what I want to do is actually take this brick layer on the exterior of the wall, and I want to slice it right about here and make the top portion of it stucco.
So let's look at the process to do that. The first step is gonna be to insert a new layer at the top of this wall. So, I've got my first layer selected, finished one there and I'm gonna click insert and that will create a new layer at the very top. Now, I'm gonna change the function to finish one priority four, and then I'm gonna click in the material field, and the small browse button will appear and I'll click that to display the material browser.
Now I want to use a stucco-like material. So I can actually type in the word stucco right here at the very top in the search field and it will filter out the list of existing materials to those that contain the keyword stucco. And this first one right here, this EIF, exterior insulation finish system will do the trick just fine for what I have in mind. So I'm gonna go ahead and select that material right there and then let me click okay. So that creates this layer and assigned it to that material but at the moment I have not actually expressed that layer in the wall structure yet.
Well, rather than giving it its own unique thickness which would add it outside the brick, what I actually want to do is split the brick and add it only to the top. So to do that I need to use the tools down here at the bottom. So, the first thing I'm gonna do is click the split region tool and then you'll get this small knife cursor up here and you can come into this preview and interactively click on any one of the layers that you want to split. So I want to make sure that I'm splitting the brick.
So I'm going to click on the surface of that brick to place a split line there. Now, I'll use the modify tool here to turn off split region. And then click in the preview and roll my wheel to kind of zoom in and see what's happened. Now sometimes the panning is a little difficult to do with the wheel so you can use the scroll bar here to pan it. Now notice that it actually placed a dimension here and a small line, and if you move your mouse over that small line, it's actually labeled as the border between the two layers.
Now I'm gonna click on that little small line. The distance that it's measuring currently says that it's 4'6" and it's measuring from the top edge of the wall. I actually want to measure it from the bottom edge of the wall. So you'll notice that there's a very small little arrow on this line, and if you click it it will flip to change the distance that we're measuring from the bottom instead of the top. And then I'll use my scroll bar here to scroll it down so that I can actually see what it's doing.
Now, notice that it says 15' 6". Now click in the empty white space to deselect and then click again to select that line, and that will actually activate the dimension just like you would get in the project environment. And I'm gonna type 16 and press enter. That will move that line slightly. So now I've defined this bottom layer as being 16 feet tall. Now here's the thing. You want to make sure that you've measured that point from your desired location.
In my case I want to measure it from the bottom of the wall. This way, whenever I build with this wall it will always have up to 16 feet of brick at the lower portion of the wall and will only add the stucco when it gets above that height. Okay, so the last step is to actually assign this upper layer to that new material that I've added at the top here. So to do that, you want to first click on the new layer. It's currently layer one.
The one with the stucco material. Then you want to click the assign layers button down here at the bottom, and then come into the preview window and click on that top region there. So I'm clicking right in the middle of that surface. That will now assign that layer to just this top portion. Now if I go to the modify tool to deselect it, you can see it's a slightly different color indicating that it's now been assigned to another material. The other thing you'll see is that the thicknesses here are both grayed out.
That's another way that Revit is letting us know that there's something connecting these two layers together. Now if you ever decide that you want to remove this effect you can use the merge regions tool and click the little line in between and it will remove that and merge them back into a single layer. But let's go ahead and click okay here. And then okay again and see what the result is. I'm gonna deselect this wall and you can see that I'm actually seeing the inside of the wall. So let me select it again. I'm gonna tap my space bar.
That will flip it to the outside and then we can now very clearly see that we've got one material down the bottom and a different one at the top. I'll zoom in a little bit better so you can see that there is a brick pattern down here and we have the stucco material up at the top. So now all that remains is to actually apply this wall to the model. So I'm gonna highlight one of the exterior walls, press tab. Click, that will give me the entire chain of exterior walls and then I'll open up my type selector and choose the one that I just created with stucco at the end of the name.
And you'll see that now all of the exterior walls now have a upper portion that contains stucco. So the first 16 feet is using brick. For the walls that are too short to show the stucco they use only brick. Now the only wall that didn't get affected was this wall right here. Now this one we'll need to create another new type for because the distance that you need to go from its bottom up to the start of the stucco is shorter than 16 in this case. So, what we'll need to do is just do an edit type duplicate and make another one that has a shorter brick region.
And I'll leave that to you as an additional exercise for practice. So, by modifying the wall structure and creating new wall types, you can actually start to manipulate the way that these walls will display on screen, and ultimately the way that they will render.
