In this video, learn how to lay out some exterior walls.
- [Instructor] Well, we have to start somewhere, and that somewhere is finding an exterior wall system to create a building footprint. In this video, we're going to lay out some exterior walls. So, let's jump into Revit. Under Models, let's go to New. For the template file, I'm going to grab my Imperial Architectural Template. Now I'm going to click Okay. Now notice in our project browser under Floor Plans, we're in level one. These are simply views of the model, but this is a great place to start modeling an exterior wall system. On the Architecture tab, go to the Build panel and you'll see you have a Wall button. Go ahead and click Wall. Under the Properties, click the drop-down right here, and let's select a very top wall, exterior brick and CMU on metal stud. On our Options toolbar, the height unconnected at 20 feet is fine for what we're doing now. The Location line, however, instead of Wall Center Line, I'd like that to be Finished Face Exterior. That way, when we lay our walls out, we know that our dimensions are from the finished face exterior. Okay. Now we can pick a point pretty much anywhere, so I'm going to pick a point like right about here. I want to move my cursor to the left. Notice that this snaps horizontally. So I'm going to type in 100 and hit Enter. That wall is now 100 feet long. I'm going to move my cursor straight up, and I'd like this wall to be 80 feet, so type in 80 and hit Enter. Move your cursor to the right. Notice that it's going to actually align with the wall below it, and it says 100 feet. You could either pick this point now where it says 100 feet, or you can just type in 100 and hit Enter. Don't worry about that temporary dimension that says 99 five and 1/16. That's coming off the center line of the wall. That wall is truly 100 feet long. Okay, now move your cursor down. I want to draw this wall 16 feet. Move it to the right. I want this wall to be 16 feet. Now hit Escape a couple of times. Perfect. One thing I like to do is model a reference plane, 'cause we're going to actually mirror these two walls down to here. So on the Architecture tab, click on the Ref Plane button right here, Reference Plane. Zoom in to this wall, and I want to go to the midpoint of the very inside face. So pick that midpoint there. If you can't find it, just hover your cursor over it, type SM. Now it's going to find it. Pick that midpoint, and draw reference plane out to about here. Hit Escape a couple of times. Now we can select that reference plane to kind of grab that grip, drag it over a little bit. Perfect. Now I want to mirror these two walls down to here. Now what we're going to do is, if I pick a window starting from the left, coming down to the right, notice that only the objects 100% ensconced within that window will become selected. Right, if I pick a window from the right to the left, notice that all it's got to do is touch those items. Either way, I'm going to select both of these walls. If you look down in the lower right-hand corner, you'll see a little filter icon with a little number two. That's how many items we have selected. Now on the Modify panel, click Mirror - Pick Axis. Now I'm going to go ahead and just simply pick this horizontal reference plane and it's going to join those lines. Now it looks pretty coarse, so what I want to do is I want to set my detail level on my View Control toolbar, click that and set it to Fine. Now we can see all of our different layers of our wall. Click on this little 3D icon right here, and we'll see that our wall actually has some brick relief. It also has a concrete belt course. We'll take a look at that in a second, because we need to close this off. Notice that we're in a 3D view, but we can go back to our level one by just clicking on this tab right here. Now right-click on this wall, and let's create some more. On the Draw panel, click on the Start-End Radius Arc button. Now we want to zoom in on this wall here. By zooming in, I mean, if you wheel your mouse wheel away from you, it'll zoom in. If you wheel it towards you, it'll zoom out. If you hold down your wheel button, it will pan. All right, so let's zoom in on this wall here and I want to pick the end point of that very heavy line. Perfect. I'll come straight down to here. I'm going to pick the end point of this line. Now zoom out. Notice that it will snap to 180 degrees. Once you see it snap to 180 degrees, pick that. Hit Escape a couple of times. There we go. Let's make sure we save this model. So I'm going to go to File. I'm going to go to Save As, then I'll go Project. Browse where you're keeping your exercise files. I want to pretend this is a project, so I'm just going to call this one, two, three, four, five, six, seven, underscore all caps architectural. Now click onto your Options right here. And for the maximum, let's just type in a one. So click Okay. Let's click Save. Okay, now in the next video, we'll add some levels to create some heights.
