Join Paul F. Aubin for an in-depth discussion in this video Adding extensions to railings, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Instructor] In this video, I want to dig a little bit into the railing type properties. And specifically focus on adding railing extensions. Now the railing extensions feature allows you to create extensions past the end of your hand rails in order to emulate and meet local building code requirements. So to do that, we have to actually dig into the railing type properties and it's a fairly detailed process to get it set up. So let's go ahead and get started here. So I'm going to select this one over here by the wall. Click Edit Type and then I'll duplicate it.
It's going to add number two. I'll remove that and add a suffix called wall return and click OK. I'll repeat that over here. Edit Type, duplicate, remove the two and call this one post return and OK. So now I have two different railing types so that if I modify one, the changes won't affect the other. However, there's another important aspect of the way railings are set up that you need to understand.
So if I select one of these railings, go to Edit Type. You could set up the horizontal members of a railing in a couple different places. So you've got rail structure here called non-continuous. And if I move this out of the way a little bit and I click Edit, you could see that I've got five rails here. And that's one, two, three, four, five right there. But notice there's a sixth rail on top of that, okay. So the non-continuous rails are all those lower hand rails. Those are not the ones we're going to focus on right now. What we're going to focus on is these down at the bottom.
Top rail, hand rail one and hand rail two. Now, notice that the top rail says circular one and a half. Let me cancel this. I'm going to hover over the railing near the top and then press the tab key. And notice that is able to highlight that top component and I can actually even select it and it says that that's circular one and a half inch. Now if I try and tab into these, nothing happens. So the non-continuous rails are just built into the railing. But the top rails and the hand rails are actually separate components that are nested into the railings.
So they behave a little bit differently. Now, the reason that's important is, even though, we duplicated this rail and this rail and made them two different types, notice that at the top of both of them, they're using circular one and a half. Therefore, if I were to edit the top rail on one, it would actually apply to the other. So let me show you what I mean here. Let me pan this over here just to give myself a little bit of room. I'll select my post return rail, edit its type and then notice down at the bottom, there's a preview button.
I'm going to click that and that's going to open up a really nice preview window here. And I can preview the results of my changes both in the dialog and outside the dialog in the view window in the background. So position your screen like this gives you the most amount of visual feedback as you're working. So we said that circular one and a half inch is assigned to both railings at the moment. So if I click on that, notice a small browse button appears right here. If I click that, that opens up a second type properties window that has the property specifically of the circular one and a half inch top rail.
Now, notice down here, there's an extension beginning bottom. So that's the one I'm going to modify. And let's just take the length here and I'm going to type one for one foot. And click apply. And as you will see, it applies on both railings. And so you might be scratching your head there again thinking, well wait a minute, we duplicated those types. I don't understand what's going on. Well, just keep in mind that both of those types are still referencing the same top rail type called circular one and a half. So what I'm going to do is set that back to zero and apply it.
And then instead, I'll duplicate it as well. So now I'm going to call this one post return. Click OK, change the length to one foot. Click OK again and then apply. And notice that it now applies only to this one. So because I was in the post return hand rail, and then I created a duplicate top rail called post return, now I've completely separated the two railings from one another. So that's an important first step.
And I know it can be a little bit confusing but it's definitely something that you have to get squared away first before you continue. Now, let me just make a few more modifications to this new circular one and a half inch post return top rail. So we'll click the browse button again. And notice that right above the length is an extension style and it currently says none. But if you open up that list, there's a few other choices like post. And that will return it back to the post of the rail. Or you can actually change it to floor.
And it will go down to the floor. Well we said we wanted this one to be a post so I'm going to set it back to that. And then notice this setting right here, Plus Tread Depth. So if I check that, in addition to the one foot, it'll add the size of one tread and it'll extend it out even further. So I'll click OK and then OK one more time. And that completes our post return railing. So the trick there was understanding that not only do you have a railing type, but you have a top rail type. And as long as you duplicate both of them, then you'll get a very reliable result, okay.
So let's repeat the process on this railing now. And we'll edit its type. And again I'll move this out of the way so we can see what's going on in the background. And even though you could come in here and edit the top rail and choose a wall return option, that won't work. Top rails don't actually do anything with a wall return. So if you want to do a wall return, you actually want to use either hand rail one or hand rail two. Now notice that both of those are currently set to none.
So I'm going to focus on hand rail one but it doesn't really matter which one you do. And instead of none, I'll click the little browse button that will display the type properties. And up here, I've got three choices. So there's one called circular one and a half again. But notice that right below that, there's one called pipe wall mount. So that looks promising. So why don't we choose that? Now if we didn't have one that had the name we wanted, we could again just do duplicate and create one. But in this case, I'll choose the one that's already there. And I'll click OK and I'll click apply and nothing happens.
So the gotcha here now is that assigning the type is just the first step. But right above that is the position. And this can be a little frustrating when you don't remember that it's there. But if you open up this choice, it's either left, right or both. So, take a guess. I'll try left, I'll click apply. And then you're going to see that hand rail appear. So it looks like I guessed correctly. If I didn't, I would just change it to right and click apply again. So now I've got this left rail but notice that it stops right there.
There's no extension. So the final step is to go right back into the pipe wall mount, edit its properties and add the extension properties. So this time, I want to try a wall extension style. I want to do a one foot extension and I want to do plus tread depth. And when I click apply, you'll see all of those changes applied. And instead of returning back to the post, it goes horizontally to the wall. Notice also it's got these nice little support elements that are repeated along the length of it as well. So I'll click OK here to complete the operation.
So as you can see, we can add very detailed hand rail extensions that meet a local building code requirements. But to do so, you just have to be very methodical in how you go through the steps of the set up and configuring each of the parts and pieces within the railing type dialog.
First, get comfortable with the Revit environment, and learn to set up a project and add the grids, levels, and dimensions that will anchor your design. Then author Paul F. Aubin helps you dive into modeling: adding walls, doors, and windows; using joins and constraints; creating and mirroring groups; linking to external assets and DWG files; and modeling floors, roofs, and ceilings.
Paul also shows advanced techniques for modeling stairs and complex walls, adding rooms, and creating schedules. Finally, discover how to annotate your drawings so all the components are clearly understood, and learn how to output sheets to DWF, PDF, or AutoCAD.
