When a curtain wall has been drawn, and the grid lines have been established as a design, you can add mullions to complete the design of the wall. Mullions can take on many shapes, sizes and materials. The Revit architectural template that you have, has a number of mullions already downloaded for your use, and you can even modify these. You can modify 'em to other sizes, and, you can also change their materials. Let's take a look at how we can add mullions. I'm going to go to the project browser, and the first floor, floor plans and click on there, and zoom in where we have our grid set up, and painted glass.
Go ahead and click on the section head. It'll take us in to look at the design here. Now to begin with mullions, the architectural tab, under Build panel, you'll see the icon for mullion right there, go a head and click on it. And in properties, you'll notice that there's one already picked. Go ahead and click on the type selector. And you'll see a number of others that are available to you. If we wanted to go ahead and modify, mullions, the thing to remember here is, is that you need to modify the mullion first before you put it on the grid.
You cannot modify these that easily. Once you've made placement. The other thing is, is that where grid lines can be copied back and forth, when you're doing a design, you can't do the same thing with mullions. It's kind of like a, a one time shot, and so you can't really copy 'em, you have to place them. So, let's take a look at something else with it too. Let's go to, edit types. We're going to look at this mullion, just so you have an idea as far as what's available to you. You can come up and do duplicate, and you can duplicate it. And once you do that, then you can modify the information that you have here.
Now, this kind of information, as far as material and things, is easy to go ahead and change, which is a little tougher to do is changing the dimensions and the thickness. You might spend a little time playing with that, before you do anything. I'm going to hit Cancel. And the first one we're going to work with is the grid line that goes all the way across. And I'm going to do the six verticals right off the bat. going to click this, here, here, so forth, and so on.
Now the next tool is, grid-lined by segment. And I'm going to pick this, and I'm going to come over here and you can see that it's being done now, by segment. So you can do it individually this way. And don't forget that there's also mullions that go along the perimeter as well. So you could you know, put in stuff like this on the bottom.
Remember the doorway doesn't exactly have one. And you can go to Grid Line again, and finish off basically the sides, as I'm showing you up here. So you've got a complete grid. There's a couple of other things though, that you can work with. Let's go back up, and we're going to do an undo of all these mullions. And we're right back to where we have just the grid lines again. Go up to All Grid Lines, and click on it. And then come down and click on the grid somewhere, and you'll see that all the mullions get placed.
Let's do basically modify. Okay? And another undo. And go back to mullion again. This time, what I want you to do, is hold down the shift key, and place, and you'll notice here that I'm kind of overriding everything. Notice how the shift key, will also invoke single grid-line segments as I do that. If I hold down the Ctrl key, and touch the grid, it brings everything back in again.
So, there's a number of different ways that you can do it because quite frankly, putting in mullions can be very tedious. You might want to take advantage of some of these, faster tools, and then edit out what you don't need. The last thing here is we don't need this particular one. So I'm just going to go ahead and delete it out, with the delete key. So I'm going to come up here and hit modify. And we have basically our grid completed. The other thing that you might want to look at, is how the mullions are connected. And in this case, if you click on an individual mullion, you'll notice up here on the ribbon, you have a way of breaking, the, mullions or making them continuous.
So I'm going to come in here and click continuous, on this one patch, and you'll see how it comes across. Now if you want this to be a little bit different over on this side, you can basically break that join, or make it continuous again. And it comes in. So you can play basically with how you want, your mullions to be broken, or joined. Couple other little notes about mullions you should be aware of, is if you can pick the grid line with a mullion on it, if you go ahead and cycle through, by hitting the tab key.
You will finally end up on getting to a grid line. If you go ahead and move that grid line, the mullions are going to go with it. If you go ahead and delete the grid line, it's also going to delete the mullions. And you can though, delete a mullion, and keep the grid line. So, there's a couple of little twists there that you should be aware of. When you're working with mullions. The last thing is, is, is that just make sure, that when you're working with mullions, that you go ahead and decide first of all what mullion type you're going to use.
You can use the Tab key to do a general selection, to get them all in place. You can also use a Ctrl key, to place mullions on a empty grid. And just remember that mullions are not modifiable in properties after they've been placed. However, you can go ahead and modify those things, and change the materials, before placement.
