This course offers an in-depth look at the rendering features of Revit, including photometric lighting, sun, and exposure and its basic animation tools. Author Paul F. Aubin covers creating 3D views; modeling wall layers, sweeps, and custom components; applying materials and custom textures to objects; and rendering the final scene with optimal quality settings. The course also shows how to create a walk-through that showcases designs.
Whether you're creating a model for construction documents, for rendering, or for both, you will most likely create the walls pretty early in the process. Walls are perhaps the most basic building component of any Revit model. In this movie we will assume that you already know something about creating walls and therefore focus on some issues that we will want to consider when preparing the walls in our model, specifically for rendering. So I'm in a file called Office Walls, and there's a 3D view in a file called Exterior Walls. And all I have done in this view is select all the walls and isolate them and hidden all the other geometry.
It just makes it a little bit easier to focus on the walls for this exercise. I am going to select one of my exterior walls; it doesn't really matter which one. And what I usually like to do is create a copy of it off to the side. So I am going to come up here to the Modify panel and click the Create Similar tool, and I'm just going to draw a little segment of wall off to the side here. The main reason for doing this is I can kind of work on this wall separately. If I like what I've done, I can apply it to the other walls; if I don't like what I've done then I can just scrap it and try again.
So it just kind of makes what I'm doing a little less permanent. Go ahead and zoom in on this guy. I am going to select it, do Edit Type, and that takes me to the Type Properties dialog. So the first thing that we want to do is click the Duplicate button at the top and create a copy of this wall type. It suggests the same name with a number 2 at the end, and I'll take that off, and I am going to add a suffix called Stucco. Click OK. Now that's the name of this type. And then I want to click the Edit button here next to Structure.
Now I'm not going to get into all the details of editing layers. We actually cover that in the Revit Essential Training class here in lynda.com, so you feel free to take a look over there. Really this would just be focusing on the vertical structure down here. Now of course, when you look down here you will notice that everything is grayed out. There's a little note here that says this works in Section Preview Only. So I am going to click the Preview button here, make sure this says Section, and then suddenly all those buttons light up. So, that's what that little message means right there.
If this is in plan, it doesn't work; they are all grayed out. So you've got to have both the Preview turned on and the section Preview enabled in order to see these buttons. Now when you're in section Preview, you can actually adjust the Sample Height if you want. What this does is actually changes the height of the little wall there, but that's really just a sample wall. It's not the actual wall you're changing, so that's why they call it Sample Height. 20 feet works well for me in this example. Now I do want to insert a new finish layer, so I will make sure layer 1 is selected, because whenever you click Insert it will go above the one you have selected. And I am going to create a second finished layer that I want to assign to my EIFS Exterior Installation Finishing System material.
Now we are going to talk about materials completely in a future chapter, so for now I am just going to assign from one of the built-in materials. Now that's all I need to do initially, because what I actually want to do is apply this new item that I have added here to only part of the finished layer over here. So the way that we do that is we actually go to the Split tool down here in these series of vertical structure buttons and I get this little knife cursor. And when you move along on one of the existing layers there, you will see a little temporary dimension.
Now I actually want this thing to be 16 feet off of the floor, and I am going to try and get that dimension to comply there and click. Now what if the dimension didn't comply? Sometimes the dimension will flip to the top side. Let me first of all reset with the Modify tool right here. Click on Modify. I am going to click in the Preview and start rolling the wheel mouse. It turns out that you can select this little line right here, which was created from splitting, and there's a little flip grip on it.
If I click that, it actually flips the dimension up to the other side. Now I do want it measured from the bottom because when I use this on varying+ height walls in the project, I want the base 16 feet to be brick, and anything above that I want to use this Stucco material. So that's why it's important that I get the measurement to go to the one side or the other. Now the other thing is this temporary dimension actually can be active.
So if you didn't get it exactly at 16 feet, you can zoom in on this, click your Modify tool, select that little line, and then click on the dimension and actually type in some other value. Sometimes a little tricky, the interface here, but scrolling actually sometimes works better with the scrollbars in this interface. What I want to get here is just make sure that's 16 feet off the ground, and then this little material that I have created at the top I want to assign to the new material here.
So I am going to zoom in on it, and the way we do that is with the Assign Layers button. So what you do first is you select your new layer, come over here and click the Assign Layers button, and then click on the region. And when you do that, it will assign this layer to just that region. This outer finish material is now divided into two separate regions, and it's using layer 2 for the bottom half and it's using layer 1 for the top half. And we could continue to split and create additional regions and assign them to different layers that we create.
You'll notice over here that the two layers gray out. That's kind of Revit's way of letting you know that they are linked together. If you decide you no longer want this, you can use Merge Regions to put them back together, and then you would just click that little tiny line there in between. So let's click OK. Let's click OK again. And I will deselect the wall so that you can see the result. So notice that the top half no longer has a brick hatch; the bottom half does. If I zoom in and I turn on shading, I get my brick pattern down here and this tan color here--that represents the stucco up above.
Let me go back to a hidden line view, and now all that remains is to assign it to the remaining walls. I'll just use a tab selection here, select the entire exterior shell, open up my List, and assign it to my stucco wall. And you'll now see that the brick band goes all the way around. Over here, these walls are too low to actually use the upper material at all, so they're not seeing any stucco.
Here we have got the stucco just in the top half. Now this one wall right here is going to need some special treatment. I'll leave that to you as an exercise. The reason for that is because the base of this wall actually starts much higher than the other guys, so as it measures up 16 feet relative to its own base, it's rendering that wall completely in brick. All we would need to do is repeat the process, create another type, and set the height just a little bit lower, and that will be a good practice exercise. Using the tools under the Modified Vertical Structure within the wall type dialog, you can split regions, you can assign those regions to different layers in the wall structure, and you can merge regions back together if you like. And doing all of this allows you to start articulating the overall vertical structure of the wall and layering it vertically as well as what we were able to do horizontally by just adding layers in the first place.
