Join Shaun Bryant for an in-depth discussion in this video Changing elements within a curtain wall (grids, panels, and mullions), part of Cert Prep: Revit Architecture Certified Professional (2016).
- [Voiceover] We're now in a new chapter of our Revit Architecture Professional Certification preparation course, and we're looking at elements and families in this chapter. The first thing we're going to look at is changing the properties of a curtain wall. And as you can see, we've got a new project open. It's called RevitProject_CURTAIN. You can see the name of it at the top of the screen there. And as you can see, we are in the north elevation here in the project browser. If you go to the floor plan, level zero. You'll see that it's just one wall.
As you can see if I just zoom out, there's one wall with a curtain wall inside it. That's it. We want the north elevation in this case so that we can see the actual front there of our curtain wall. A curtain wall is basically a glass wall inside a host wall within Revit. So I'm gonna zoom in nice and close to get my curtain wall sitting there nice and central on the screen, like that. You'll notice that the detail level is set to fine. And we're also working with a shaded visual style there on the view controller.
What we're going to look at are things like mullions, panels, and grids. At the moment, here's our curtain wall. If I click on that there, can you see? The outside edge and the type selector in the properties now are telling me that I've got a curtain wall there set up in my particular Revit project. So I'll just click away to deselect that. We've got one grid. If I click there on that, it is a mullion. And as you can see, it's a rectangular mullion 50 by 150 millimeters there. And if I click away, that is just one particular mullion.
What I can do is I can add more grids and add more mullions. When you create a curtain wall in Revit, all it does is it gives you that outline with the exterior four mullions. What I've done is I've added mullions to each of those four lines that forms the rectangle on the outside of the curtain wall. As you can see, the top offset is minus 500, which is that little distance there. The little piece of brick above. I just hit escape there to deselect. If I want to add more curtain grids, I go to the architecture tab on the ribbon. Into the build panel, and there's my curtain grid right there.
It creates a grid line in a certain curtain wall or curtain system. If I click there, can you see? If I hover now, can you see there? It places a new grid going across like so. And it places that equally. Now I can easily just click there on the temporary dims. Change that to say, 1,000, like that. And it'll move that grid up for me. Now I can place another one if I want to, there like so. And I've got the temporary dims again. So that one's 1,250. I'll change that to 1,000 again, like that. Again, you can follow along with this in the video.
You can patch change the values if you wish. I'm gonna hit escape now just to deselect the curtain wall. And you'll see I've got some new grids there, now. And they are just grid lines. They're not mullions yet. But if I select that, now. Can you see I can add remove segments if I want to? So I can add or remove segments in a curtain grid. If I click there, now, I can now select and remove grid segments if I want to. Now, I don't want to add or remove any segments in this case, so I'm gonna hit escape. I don't want to select any of those. That's why I clicked away from them, to deselect them.
I can now add mullions like so. And if I select here, can you see it's adding a mullion? And that's that 50 by 150 again. Just the default I've got in this particular project. So now, can you see, I can add a grid line segment. I can put all grid lines and so on. What it's doing there, it's giving me the option to place the mullions on a grid line, grid line segment, or all grid lines. So what I'll do there, now, is I'll just hit escape once. I'm gonna undo what I did. I'm gonna take those mullions off off of that one. I'm gonna go back to mullion here and I'm gonna go for a grid line segment.
If I hover there, now, can you see, it places it only on that grid line segment. Not this part of the grid line on the right. As you can see, I can now edit that quite happily like so. What I can also do is I can select the actual curtain wall like so. If I scroll down here, you can see that I've got a vertical grid, angle and offset, and a horizontal grid, angle and offset. If I change the vertical grid offset there to, say, 500, watch what happens on the screen. Press enter there, apply that. Can you see, it moves everything over to the left by 500.
That vertical grid there is moved across to the left. The horizontal grids, on the other hand, if I go in here like this and change that to 500, watch what happens. If I apply that, now, you'll see that they all move up by 500. That's because it's a positive 500 in each direction. If I put negative 500, it will go in the other direction. Let's undo those last two steps. One and two, like that. Now, I'll select the curtain wall again. And I'll come down here, and I'll change the offset now to minus 500 on the vertical side of things.
And I'll click on apply, and you can see it goes to the right. If I do the same with the horizontal grid, again, minus 500, watch what happens. And again, it drops it down again, like so. I'll hit escape, there, just to deselect. Now, if I select the curtain wall again. Keeps all those values in place. If I come down here, I've got structural settings. Because you do get structural curtain walls. And you've got the data there as well. If I go into edit type, now, here, it brings up the type properties. So it's telling me now the vertical grid layout, the horizontal grid layout, the mullions, the interior type, border type.
I can change all of this in here if I want to and create a new curtain wall type. Its function at the moment is exterior. I can automatically embed it in a wall. What you'll notice is this one is automatically in a wall. What will happen there is if you tick that box, when you place the curtain wall inside the host wall, the brick wall, it'll automatically cut the wall to suit the curtain wall. If that's unticked when you place a curtain wall, the curtain wall will go inside the wall. Let me show you what I mean.
I'll just cancel that now, and what I'm gonna do is go to the level zero floor plan. You can see there that I've got that curtain wall there. I'm gonna zoom in on the right hand segment of the wall, here, and I'm gonna go to wall, here, and I'm gonna select curtain wall. It's already selected it for me because that was the last wall I selected. If I come here, pick a point there, and then drag that across to, say, 2,500, I get a warning. That warning has popped up, I'll just bring it up on the screen for you. It says, "Highlighted walls overlap. "One of them may be ignored "when Revit finds room boundaries.
"Use the Cut Geometry command to embed one wall within the other." There's the cut command. And I would select the outer wall and then the curtain wall to cut the curtain wall out of the outer wall. I can close that warning, it's a soft warning. Now, what I can do is I can go and select my curtain wall. What I need to do here is just make sure that I'm selecting the curtain wall and not anything else. I click on it like so. And if I go to edit type now and I switch that all to automatically embed on and I okay that, can you see, it automatically cuts it out. And if I go now and look at the north elevation, it's automatically cut out of the wall.
It's a bit too high, obviously. So what we'll do is we'll select that and just drop that down to the level one, for example. It's unconnected at the moment, so I'm just gonna bring that to level one. Apply that, and that fits it into the wall like so. So that automatic embed there in the edit type is what we need. Notice there, it's gone to an elevation marker. Because I'm just in the elevation right now. Make sure that you select the curtain wall first before editing the type. And I'll just switch that off again so we're back to the default settings. So that's how you work with curtain walls.
Embedding them, cutting the geometry, adding grid lines, adding mullions, and so on.
