Hello. We are going to take a look at advanced modeling in Revit. And in this particular lesson, we're going to take a look at creating stairs. Now, before we get started, I'd like for you to note that I am running Revit LT 2022. And I am about to create a brand new project. So let's go ahead and get your Revit running. And once you get that started, let's go ahead and follow along. Now, to begin off this lesson, we're gonna start off by creating a brand new Revit project. So from the start page, just clicked on Models, New, and I'm just gonna choose Residential Imperial. It doesn't matter which template you use but this is just the one I'm gonna use for this lesson. I'm gonna say OK to create this new Revit project file. Now, to create our stairs in Revit once our project loads, we're going to go to the Architecture tab in the ribbon, so I'm gonna come over here to the Architecture tab. It's already active and then from there, we're gonna go over here to the stair tool. Go ahead and click on this and our Contextual ribbon changes to the modify, create stair contextual ribbon tab. And creating stairs in Revit is a form of sketch modeling, similar to creating floors or ceilings in Revit. So instead of sketching with lines, you're gonna be sketching with components. So over here, these are the way that we're gonna use to create our stairs. We can create a straight stair room. We can create a full step spiral. We can create a center in spiral type. L-shape winder. And U-shape winder. So by default for this one, we're gonna just create a stair run that is straight. So after we've done this, now we're gonna go down to the options bar and we're gonna choose some of the options as they're specified here. So we have the location line for our stairs where this is gonna be run center line. These are the other options. The exterior support left, run left, run center, run right and exterior support right. Now, what this is going to do, let's go ahead and just click anywhere out in space to begin creating our stairs. And let's zoom in a little bit. So right now, the location line is set for run center. So notice that the dashed line in the middle is the location line. If I was to change this to let's say exterior support left, now when I'm creating it, the location line is at the exterior of the stair supports. If I was to change this to run right, it would now be at the right of the run. So that is what the location line will do. If I wanted to, we can create an offset for this while we're creating our stairs. This will offset it from the location line for where we're placing it if we wanted to. The actual width of the run, you can specify this here as well. And whether or not it's gonna create an automatic landing. So I'm gonna change this back over to run center. And I'm just drag out. Now, notice, as I'm doing this, it's giving me in the tool tips the number of risers created and how many are remaining. These properties are controlled over here in the Properties panel. For now, let's just go ahead and drag this all the way out until we've created all of the risers and there are zero remaining. So in this case, we've created 16 risers and there are zero remaining. Even though I am dragging out further, it will not create anymore stairs because I have satisfied the calculations for the stairs. So I'm just gonna go ahead and click to complete the stair creation. You're gonna zoom in on the stairs. Let's take a look at the Properties panel for the stairs. So our base level for our stairs is the first floor. We're on the first floor right now. The offset, if you want to specify an offset, you can do that here. The top level of the stairs was going up to the second floor. You can change that to any other floor levels that you have in your project. Gonna leave that as second floor. The desired stair height right now is set for nine foot. It's grayed out. If you wanted to set your desired stair height, you would need to change this floor level to none, and that's gonna make this available. I'm gonna change this back to second floor to continue on. Here also, if we scroll down some, you have the desired number of risers. Ours was set for 16. If I was to change this to 18 right now, by pressing up on the arrow, now when I want to create a new stair run, 'cause we're still in the stair creation tool, we can but it'll have 18 risers. That will change it to 18 but it will not automatically update what we currently have set for these stairs. I can modify the stairs by dragging the edges of them. I can flip the stairs as well. Notice the arrow is going 13 down. Now it's going 13 up. Let's go ahead and place another straight run. It's gonna be by run center. I'm gonna come down a little bit from here. And I have automatic landing turned on, so it's gonna create a landing between these two stairs while I finish out the number of risers. And as I've done that, number of risers have been created. I have 13 on this run, and then I have the remaining to hit 18. So that was a look at creating a straight run of stairs in our model. Join me in the next lesson where we will take a look at creating spiral stairs.
