Adding foundation walls

Okay it's time to start thinking about foundation walls. So let's just get started. Under models let's go open. Browse where you're keeping your exercise files and in chapter 3 we'll grab structural 03-01. Click open. Okay we haven't really added any walls to our model yet and we're going to start doing that from this point moving forward. So we want a foundation wall that's going to support the exterior of our architectural exterior walls. So it's appropriate that we're in level one. So in the Project Browser, under Structural Plans, let's make sure we're in level one. Now, the grids that we have put in there are going to kind of be in our way for this process. So what I'd like to do is temporarily hide them. So select any one of your column lines. On your View Control Toolbar, notice that there's a little pair of eyeglasses. Click those and let's hide the category. A little magenta box appears around your view saying that you're in a temporary hide isolate mode. Okay now on the structure tab click the wall button. Notice that there's a wall and a column on the architecture tab these are non-bearing elements they're the same list but if we go to structure they actually are a structural element right so under structure let's click wall in the properties let's click the drop-down here let's grab a foundation 12-inch concrete we're going to make a larger wall so let's click Edit Type. Click the Preview button down on the bottom here. Ooh, there's our wall. For the type let's click Duplicate because I want a one foot six inch concrete wall so let's click Duplicate. Foundation, let's go with one foot there six inch concrete and Revit puts a little two on the end of that so let's just get rid of that number two click OK let's click Edit next to structure and for that thickness let's make it one foot six click OK click apply, click OK. Now here's what we need to do. Let's look at the options, right? So for depth, instead of unconnected, let's go to top of footing. We're on level 1, so we know our top constraint is going to go up to level 1. Our base constraint is going to go to top of footing. The unconnected height we'll see is six feet. We can always change that footing level and that will change our height of our walls. On the draw panel let's click pick lines. For the location line where do I want this justified? We definitely want it on the wall center line. Now let's zoom into our wall here and make sure you select the very center line of it and pick that. Come up to this wall here and pick the center line of that wall. Pan down to the end here, grab the center line of that wall, that wall, that wall. Keep going, that wall there, that wall there, and one last one here. Let's hit escape a few times. Let's go to a 3D view. Now when we zoom in here we'll see that we've got a nice fat wall underneath the exterior of our architectural building. So that was pretty quick and easy. That's how you add foundation walls.
