Join Paul F. Aubin for an in-depth discussion in this video Working with stairs, part of Revit Architecture 2016 Essential Training (Imperial).
- In this movie, we're gonna 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 gonna 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 gonna work down in the lobby in the lower portion of the plan. So, I'm gonna 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 just mentioned. Stair by component and stair by sketch. So in this case, we're gonna choose our stair by sketch. And that will take me into our traditional sketch mode. There's a few things we wanna 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're 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 wanna try and use run wherever you can. If you look at the tool tip that's appeared on my screen there, you can see 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 gonna 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 wanna make sure run is chosen. Next, I wanna look over here on my properties pallet and verify that the settings here are correct and what I expect.
So, I'm gonna 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, and 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 stair 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 outta here, it's just 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 18. Now, you can actually modify that number if you needed to, but you can't modify to a point that makes the riser taller than seven inches. If you do, Revit will generate an error message. Now, we have a width parameter right here, as well, and I'm gonna 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 gonna 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 wanna pay attention to that message because that's letting you know, basically, when you need to click. So, what I'm gonna 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 the 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 the landings, Revit takes care of the landings, let me show you. I'm gonna 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 gonna put a window around the whole thing, we can use our standard modification tools like the move tool, and I'm gonna move from this end point, and I'm gonna snap it right to that end point.
And that gets it positioned at the correct starting point. Next, what I'm gonna do is select only this half of the stair because, you see this nice little gap over here to the wall? I wanna match that same amount 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 right over here called activate dimensions. So, make sure that you have just the right hand side of the stair selected, you click on activate dimensions, that will give you a series of temporary dimensions in 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 wanna 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 wanna have a five foot landing, it's really up to you. So, the last thing I wanna do before I finish this sketch is over here on the ribbon, I wanna 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 gonna use. So, if I wanted a particular type of guardrail, or a hand rail, or something like that. So, in this case, I'm gonna just choose a guardrail pipe. And I'm gonna assign it to the stringers. And then I'm gonna click okay. 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 gonna 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 gonna do this one, also, with the stair by sketch. But I just wanna point out that you could easily do this with stair by component, as well. Let's do stair by sketch. I wanna verify all my settings again. You can see it remembered all the same settings. I'll start right about here. And I'll pull it all the way to the end. So, the only thing we do differently this time is we use 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 a guardrail pipe, and I'll click finish.
Let's reopen our section. And there's our result. You can see that I'm a little off right there, so I could 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 use the same sketch based methodology that we've looked at in other movies, like floors, and roofs, and so on. You sketch the overall runs of the stairs and then from that sketch, Revit creates the three dimensional stair.
Paul also shows advanced techniques for modeling stairs, complex walls, and partially obscured building elements, as well as adding rooms and solid geometry. Finally, discover how to annotate your drawing so all the components are perfectly understood, and learn how to output sheets to DWF, PDF, or AutoCAD.
