Join Paul F. Aubin for an in-depth discussion in this video Adding levels, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Voiceover] Levels of the primary organizational construct in a Revit project. Now we have a few different datum elements to choose from. We have levels, we have grids, and we have reference plains. Levels and grids serve very specific purposes within your project. The level demarcates where the actual important heights of your project are, and grids are usually used to locate columns and other structural grid elements. So in this movie, we're going to talk about the levels. Now the first thing that's important to understand about levels is you can't manipulate levels in a floor plan view.
So notice here on the project browser that I'm in the floor plan level one, and of course, we're seeing it here on screen. So what I'm going to do is double-click the east elevation to open up that view instead. And then the levels that are already in the project will display here. Now you can see that the level is represented by this dashed line. Now, the right way to think about that is imagine that it's a plane cutting through the building and parallel to the ground. It's parallel to the ground at a height of 12 foot 8, and this one is parallel to the ground at a height of zero.
And these are in the negative direction. So each of these levels locates an important height to our building. Now, what I always like to tell people is, if you have a button on your elevator, You should have a level there. So in this case, we only have a level one and roof. So there wouldn't be any elevator, per se. But if this was a five story building, and we had five levels, then we would want to create a level for each of those stories, and those would be the locations that you would expect to see in the elevator. But as you can see, we have levels for other things as well, like the bottom of the footing, or the top of steel, or the roof itself.
So any important height that you want to reference in your project with geometry or that you want to just call out on the elevations here, that's a good place to put a level. So let's talk first about the levels that we already have. These levels are part of the template that we started with when we created the project. This dashed line represents the actual height of the level. If you select it, you'll notice that it's got some control handles and grips on both ends. So at both ends, you have a little small open circle.
And you can actually drag that small open circle, and notice that the other levels drag along with it. That's because of the small padlock icon right here that keeps them all locked together. And that works on both ends the same way. In this case, all the annotation moves along with the endpoints of the levels, and you can actually control which sides have the annotation, which sides have bubbles, using these checkboxes right here. So this side, it would hide the bubble, and on this side, it would show the bubble.
So if you want to reverse which side is showing it, I'm going to put it back over here on the right, and then I'll drag these levels back a little bit like so. So that gives you a little bit of control over the extent of the level and the graphics that are displayed. Another graphical control that we can do is right here, the two labels are sitting right on top of each other. It's very hard to read. Well, if I select the bottom of footing level, what you'll notice is that there's a small little zigzag grip right there, that if you hover your mouse over it, it says add elbow.
And if I click that, that's exactly what it'll do, is it will add a little kink in that level, and I can adjust it with these grips. And notice that it doesn't change the height of the level. The height is still measured here, and it's still indicated here. All that did was move the location of the bubble to make it more legible. So you can do that any time you want, to customize the way that a level actually displays. Now, I want to direct your attention to the project browser.
Notice that we have a bottom of footing floor plan. We have a foundation floor plan, a level one, a roof, roof framing. Many of these floor plans have a corresponding level. So when you see the color of the bubble here is in blue, what that indicates is that there is a corresponding floor plan. And if you hover over that blue bubble, it will tell you that you can go to that view, and you would do that, actually, by double-clicking that symbol.
And that would take us back to the floor plan. I'm going to return to the east elevation. Now it's possible to actually create a level that doesn't have a floor plan. And, in fact, it's possible to remove a floor plan from an existing level. So for example, I don't really need a top of footing, or a bottom of footing floor plan. So if I don't want those, I can simply select them here on the project browser, and notice that when I delete that floor plan, the color of this symbol changes to black.
That indicates that it's just a datum now, marking the -6 location, but it does not have a corresponding floor plan. So, if ever you decide that you don't want the floor plan that goes with the level, you can easily remove it. Floor plans must be associated to levels, but levels can exist independent of floor plans. And we're seeing that right here. But it would not be possible if you deleted the level. So if I deleted the top of footing, it would also warn me that it would have to delete the top of footing view as well.
The view cannot exist without its parent level. I'm going to cancel this instead of going through with it. Now, my building needs a couple more levels. So we only have level one and roof. I actually want to create a level two and actually another roof level. So we're going to create two new levels here. So what I'm going to do is hold my wheel in and drag down a little bit, and then I'll roll the wheel down slightly, just to zoom out, to give myself a little bit more room to work. The level button is here, on the datum panel. And notice that if you hover over it, in parentheses next to the word level, it says LL.
That's the keyboard shortcut for the level command. So you can either click this button, or you can simply type the letters LL on the keyboard, and that will run the command. So either one will work just fine. Now I can start somewhere over here, and notice that it will find an extension alignment to the existing levels. Click my point, and then drag somewhere over here. And again, it will find where they snap together. If I line it up on both sides, you'll see those dashed lines and those padlock icons appear, indicating that these levels are now all connected together.
And as we saw earlier, if I stretch, they all stretch together. Now if you look at the bubble for level two, you'll notice that it's currently black. However, if you direct your attention over to the project browser, you'll notice that I already have a level two floor plan, and a level two ceiling plan. In addition to that, I actually have a new level two structural plan as well, and I can see that if I expand this group right here. Now, when I expanded that there, that cancelled the command.
So let's go back to the level command, and what controls that behavior is this checkbox right here, that says make a new plan view. And in the plan view types button that's next to it, you can select which kinds of views you'd like to have. Now, the next level that I'm going to create is for an upper roof, so all I need there is a floor plan. I don't need a ceiling or a structural plan. And in fact, i'm going to get rid of this structural plan in a minute, because I don't really want that one either. So I'm going to select floor plan only here, click OK, and then draw my next level here.
I'll click my modify tool to cancel the command, that color will change blue, and I now have level three. Let's take the level two structural plan here, press the delete key on the keyboard, and get rid of it. As far as the ceiling plans go, I should only have level one and level two, so that's fine. But I do want to make some adjustments to these other floor plans that we have here. It turns out that, by default, there's a connection between the name of the level and the name of the floor plan. So if you click right on the new level that we just created, you can edit either the name or the height, by just simply clicking right on it.
In this case, I'm going to click on the height and set that to ten feet. So that will move level two up. Then I'm going to click on the roof level, and click on the name this time. Click in front of the name and change that to low roof and press enter. When I do, Revit will ask me if I would also like to rename the corresponding views. So there's a roof view right here, and I'll answer yes.
And now I have a low roof floor plan. And then I want to select this level and I'm going to change both things. I want to change the height and make it 20. And then I want to change the level name and call this high roof. And again, I will answer yes here, and it will rename both the level and the corresponding floor plan right here. Now, as a final finishing touch, I can add the elbow, and make an adjustment to the graphics here to make everything a little bit more legible.
So early in the project, it's a good idea to go in and think about where you need your floor levels to be. And set those up. You do this from an elevation view. You can add new levels or you can manipulate the ones that are already there. And then, you can even have floor plans associated with those levels as required.
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.
