Join Brian Myers for an in-depth discussion in this video Creating exterior walls, part of Designing a House in Revit Architecture.
At the start in most projects it's very likely that you'll start by drawing your exterior walls. At least that will be the first thing that you model inside of your project. Now in order to be able to accomplish that, you need to come into your first floor plan and then come up here to Walls underneath the Home tab. Now by selecting on that you'll have a pulldown list here that's called your Type Selector list, and you'll see that there's a wide variety of different kinds of walls that we can choose from. In this case, we're doing a residential design. Because we're doing a residential design, there is going to be a lot of brick and siding and that kind of construction.
Depending on your area of the country, you might have different things, maybe adobe, or different kinds of construction that are available to you. But in this case, we're going to go with something very common, it's just going to be siding for our exterior walls. I'm going to come in here and I'm going to select on the Exterior Siding wall. Now this is just your typical 2x4 construction. In order to be able to see that, if I select on the Edit Type button here, I can then come up here and select on Edit right next to the word Structure, and we can see each layer of material that's available to us.
In this case, I was saying that this is a 2x4 wall, and it says this is 3 1/2 inches thick and that is true because your typical 2x4, once it goes to the milling process, ends up getting down to about 3.5 inchesx1.5 inches in size. So it's not actually 2x4, it's something just a little bit smaller. And you can see here whether it's siding, or sheathing, or whatever the case may be, each material inside of this wall has its own real-life thickness associated with it. In reality, this wall is a total of 5 inches thick, but we're still going to call it, at least I'll probably still call it a 2x4 wall because that's really the terminology for it.
I'll go ahead and click on OK, I'll select OK again, and it's an Exterior Siding wall. I'm going to begin by actually coming up here to where it has this Location Line and I want to make sure that this isn't to the Finish Face Exterior. I'm going to draw this to the Core Face of the exterior. Also, we need to check on a few other settings first. One is, is that the base constraint of it is going to be on the first floor, and what that means is that the wall, the bottom of the wall, the base of the wall, is going to be drawn from level 1, the first floor.
But on this case it's saying it's trying to give us a base offset at 8 foot, and that's just not right. So I just want to say that it's 0 feet to 0 inches off of the top of the floor. The next thing, I need to just know what the height of this wall is going to be. You can see right now it's saying that there is a Unconnected Height associated with it, and that's not right because in this case, it would have made the wall 9 foot tall and that's not exactly what I want. I want it to come up to, Up to level: TOP, and that's the Top of Plate. And the plate is the boards that run along the top of the wall.
Finally, this wall has something a little bit special and that is that it has siding going down the outside edge of it. And I'd like that siding to do a couple of different things for me. One, I'd like it to hide the structural members of the floor, so that when we build this house up, we can't see the boards on the outside of the building that make up the outside edges of the floor. We need something to cover that up and in this case, it is going to be the siding. Also the siding is going to cover a little bit of the foundation wall, which is just going to achieve part of the look that we want to accomplish.
Now in order to do that we need to adjust the base extension of the wall, and in this case, I'm going to make it be 1 foot 8 inches. Now that's going to bring the siding on the wall down 1 foot 8 inches below where the structural members of the floor are currently drawn in. And we'll see that here in just a minute. Now I'm going to go ahead and start drawing these floors in. I'm going to move my cursor just somewhere in here and this is probably a good spot. I'm going to click once.
You'll see as I move down, let's draw in the wall straight down, that blue dash line shows up there, that's on the Core Face which means it's on the outside edge of the 2x4 walls, the actual structural members that hold this wall up. So I'm going to come down and we're going to go down 10 feet. So you just type in the numbers 10 foot. Next, I'm going to move over to the left, I'm going to type in 16 foot.
You can see how it's automatically cleaning these walls up at the corners. I'm going to come up, 46 feet now with this wall. I'll move over 36 feet for this wall, I'll move down 33 feet 8 inches. Now we have something special going on here at this intersection and where this wall is going to be at. This instead set of being a siding wall, it's going to wall with brick.
So in order to do that, I'm going to hit the Escape key on my keyboard just once, it still keeps me in the Wall command, but it allows me to change to an Exterior Brick style of wall. And it's still built with 2x4s, but it now has brick on the outside instead of siding, and of course brick is much thicker than siding, so when we start to draw this wall in, we'll see that this wall is going to look thicker than the wall that we were just drawing. Now I want to pick this spot in particular because this is on the actual structural face of this siding wall, and we want that to line up with the same materials that are inside of the brick wall.
Now I'm going to zoom out and this should come down 2 feet 4 inches. Now if I've done everything right, I should be able to type in 20 feet here and have it automatically clean up here at the intersection. And if I hit the Escape key a couple of times to get out of the Command, you'll see in fact it has cleaned itself up appropriately here at the intersection of these walls. If we take a look at this in a 3D view now, we can see all the walls have been drawn in here on the outside.
You'll also see this line is going on here, and what's actually happening is that this wall is thicker than this part of the wall down here. This is that extension that we put in toward the start of the exercise. This is that -1 foot 8 inches base extension, where the siding is coming down to this point right here, so that you can overlap the floor materials as well as a little bit of the foundation wall down below. By using these steps, you'll be a success in placing the exterior walls in any of your Revit projects.
