In this movie we're going to look at stairs. Stairs come in two varieties here. We have a component based stair and we have the traditional sketch based stair. In this movie I'm going to focus on the traditional sketch based stair. I'm in a file here called sketch stairs. And I'm in the level two floor plan. And I'm going to work down in the lobby in the lower portion of the plans. So, I'm going to zoom in right here on this area of the plan right here. And it's labeled stair A. Now, if we go to the Architecture tab, we'll find the Stair tool, and if you click the little drop down, you can see the two types that I mentioned.
Stair by component and Stair by sketch. So, in this case we're going to choose our Stair by sketch. And that will take me into our traditional sketch mode. There's a few things we want to do before we start clicking points in the stair sketch. The first thing is, there are a couple draw modes, like we've had in other sketch modes. We've got Run, Boundary, and Riser. Now, Run is by far the easiest mode because it will actually create all the pieces that are required in the sketch with just a few clicks. So, you typically want to try and use Run wherever you can. If you look at the tool tip that's appeared on my screen there, you can that the sketch will come in three colors.
You'll have a green color, which represents the boundary lines, the outline of the stair and you're going to have an outline on either side. You'll have a blue line, which runs down the middle of the stair, and that just represents the path of the stair. And then finally you'll have some black lines which represent the riser lines. So, I want to make sure Run is chosen. Next, I want to look over here on my Properties pallet and verify that the settings here are correct and what I expect. So, I'm going to start at level two because I'm in the level two floor plan and I want this stair to go up to level three. So, those two settings are fine. That will determine for me, how many risers Revit needs to create. So, because I'm going, up to those two floors, it does the math. It based that math on the maximum riser height.
An you can see that, right here the actual riser height is just shy of seven inches. Well, if we were to click Edit Type. You can see here that the type for the stairs is seven inch max, 11 inch tread. If we were to click Edit Type and scroll down. What you would see here is that under Risers, the maximum riser height is seven inches. So, if I cancel out of here it's simply doing the math and trying to get me as close to seven inches as it can. And it came up with a number of risers of the 18th. Now, you can actually modify the number if you needed to. But you can't modify to a point that makes the riser taller than seven inches. If you do it will generate an error message.
Now, we have a width parameter right here as well, and I'm going to change that to four feet. You can change it later, but it's usually easier if you remember to do it first, because then the size of the stair is a little bit easier to control, so I've got that. And then I don't try and get my stair in exactly the right spot first try, what I usually do is I click nearby. And just kind of build it nearby and then I'll move it into place. I find that a little bit easier. Now, I'm going to start moving my mouse down, and I want you to look very carefully at the little message that appears directly below my cursor.
So, you can see that the message currently says nine risers created nine remaining. You want to pay attention that message because that's letting you know basically when you need to click. So, what I'm going to do right now is click my mouse. And that creates the first run of stairs. Now, you can create as many runs in your stair as you need. So, each time you create a Run, what will happen is, when you create your next Run, Revit will create a landing automatically for you. To join the two runs together. So, when you're using this tool, you're just drawing the run. You do not draw their landings.
Revit takes care of the landings. Let me show you. I'm going to move my mouse over here, and keep it lined up with that one. Click. Pull it straight up, until it says zero remaining. And then I'll click again. And you'll see here how it created the landing sketch for me. So, you just draw the runs, you do that with a few clicks, and Revit sort of fills in the details. Now, once we have that, we can take this entire sketch, and I'm just going to put a window around the whole thing. We can use our standard modification tools like the Move tool. And I'm going to move from this endpoint, and I'm going to snap it right to that endpoint.
And that gets it positioned at the correct starting point. Next what I'm going to do is select only this half of the stair, because, you see this nice little gap over here, to the wall? I want to match that same amouont over here. Now, I could do another move command, but I'd have to know how far to move it. and since I eyeballed my clicks, I don't really know what that is. But if you recall in a previous movie, we talked about this really handy tool over here called Activate Dimensions. So make sure that just the right hand side of the stair selected, you click on Activate Dimensions.
That will give you a series of temporary dimensions and very useful locations like this one right here. And I can simply type in four inches there and that will move just that run of the stair over so that it's four inches off of the inside wall. If you want to make any additional modifications like selecting this sketch line for example and maybe dragging this witness line grip to here. And I could say instead of a four foot landing I want to have a five foot landing, it's really up to you.
So, the last thing I want to do before I finish this sketch is over here on the ribbon, I want to click this Railing button. And what this does is Revit creates railings automatically on the stair for me on both sides. Now, if I want to, I can actually change what railing it's going to use. So, if I want a particular type of guard rail or a hand rail or something like that. So, in this case, I'm going to just chose guard rail pipe. And I'm going to assign it to the stringers, and then I'm going to click OK. And then finally I come over here and I click Finish Edit Mode and that will complete the stair. If you look over here we're seeing just a portion of the stair going up and really the best way to see the stair is to come down to the sections. Open up section one.
Zoom in. And you can see our stair going up between levels two and three. Now, if we look at level one, we obviously need a stair down there, so I'm going to scroll over here to my level one floor plan. And I have a slightly larger lobby in this location. So, I might be able to get away with just a straight run stair over here. That's a lot simpler to create than a switch back stair because it's really just two clicks. Now, I'm going to do this one also with the Stair by Sketch. But I'm just going to point out that you could easily do this with Stair by Component as well.
Let's do Stair by Sketch. I want to verify all my settings again. You can see that it remembered all the same settings. I'll start right about here and iI'll pull it all the way to the end. So, the only thing we do differently this time is that we us up all of the risers in a single sketch. Select everything, activate the dimensions, make that four inches, deselect, check my railing. It's still guard rail pipe and I'll click Finish. Let's reopen our section. And there is our result.
You can see that i'm a little off right there, so I can just move that stair To make it match up but those are fine tuning results that you can fiddle with on your own. So, sketch-based stairs used the same sketch-based methodology that we've looked at in other movies like floors and roofs and so on. You've sketched the overall runs of the stairs and then from that sketch Revit creates the three dimensional stair

Q: Is this course valid for all of the Revit architecture products? Are there any movies in this course that do not work in Revit LT?
A: This course is designed to work for anybody learning any of the Revit architecture products, including Autodesk Revit (available as part of the "Autodesk Building Design Suite"product), Autodesk Revit Architecture, and Autodesk Revit LT.
However, some individual movies in the course are not valid in Revit LT, due to the limited feature set of that application. Those movies are:
Chapter 3 - Accessing multi-user worksharing projects
Chapter 5 - Establishing shared coordinates
Chapter 6 - Using the shape editing tools to create a flat roof
Chapter 7 - Working with stairs
