Join Paul F. Aubin for an in-depth discussion in this video Creating extrusion roofs, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Voiceover] Ceilings are planar elements, they're typically horizontal, and you can create them quickly by clicking within an enclosed space. In situations where you need a more complex shape, you can use all of your familiar sketch-based tools and create a custom-shaped ceiling. Now, I want to start by showing you the most common mistake that folks make when they add ceilings, so I'm gonna go to the Ceiling command, which is here on the Architecture tab on the Build panel, and it will default to Automatic Ceiling, and what I wanna do is just change the type of ceiling that I'm drawing to perhaps a two-by-four acoustical tile ceiling.
And then I'm gonna move into the drawing area and move my cursor inside an enclosed space, and you see it will highlight the boundary of the space with a reddish-colored line, and then I will click to place the ceiling. And a warning will appear at the bottom of the screen, and no ceiling will appear. And what the warning is telling me is, is that the ceiling is somehow not visible in this view, which we already kinda could tell right here. So what's going on? Let me click the Modify tool to cancel the command. The problem is is I'm still working in a floor plan. And where we really need to be is in a ceiling plan, because the floor plan is cut at four feet above the floor, and it's looking down.
So the ceiling is up above our head. But if I come over here to the ceiling plan and I open level one there, now you'll see a similar floor plan, but, of course, the ceiling now displays because we're cutting much higher and we're looking up instead of down. Anyway, just make sure that you're always working in a ceiling plan before you start creating ceiling objects and you'll have a better experience. So let's go back to the Ceiling command. I want to stick with Automatic Ceiling, I want to stick with my two-by-four, and I'll just go ahead and click in each of the office spaces.
Now, you can change to a different type of ceiling if you want, so I'm gonna choose the two-by-two acoustical ceiling, and maybe put that one here in the break room. And then there's a third option, a drywall on metal studs ceiling, so let me choose that one, and I'm gonna highlight the toilet rooms. And what you'll see is that it's actually creating the ceiling across both toilet rooms at the same time. So why is that? So before I place that ceiling, let me click the Modify tool to cancel. And I'm gonna select one of these walls, and notice that its top constraint is set to up to level two for a total unconnected height of 10 feet.
But if I select this wall, it's set to unconnected, and it's only eight feet tall. So what's happening is when we do the automatic ceiling boundary, it's just ignoring that wall because it's too low. So what I'm gonna do is just change the height of that wall to up to level two, that'll set it at 10 feet. Now if I go back to Architecture, click my Ceiling button. Drywall ceiling. Notice that it sees both of those spaces. Now I'm gonna change the height slightly here, and make it eight foot six, I just did eight space six, and make a slightly taller ceiling here in the conference room.
Now of course those three ceilings, it doesn't look like anything is occurring because they're just drywall ceilings and they don't have a hatch pattern. But rest assured, if you cut a section through those spaces and took a look, you would actually see some ceiling planes in there. In fact, if I open up this section, it'll look something like this. Okay, now this is not the drywall ceiling, but that's essentially what you would see, is the ceiling plane there up at the height you designated. So let me close this section. Now, in this space, if I do Automatic Ceiling, it's not going to recognize the space so well, and in fact, I don't really want the ceiling to go into the whole space anyway, so Automatic Ceiling really isn't gonna give me what I need here.
So what I want to do instead is switch to Sketch Ceiling. Now with Sketch Ceiling, it puts me in Sketch Mode, grays out the drawing, and gives me all the familiar sketch-based tools. And now I can draw the shape that I want the ceiling to have very precisely. So I'm gonna start with Pick Walls, and I'm going to pick this wall, this one, this one, and this one, to give me the edges over on the left, top and bottom. In this space, I wanna kind of go along this edge of the balcony here.
Well, there I'm gonna use this Pick Lines option and pick this leading edge of the balcony line right there. Now, if I zoom in around this column right here, you'll see that I've got a small gap right here, so I'll just simply switch to the line-drawing mode and just draw a small little segment of line to close that off. And now I need to use my Trim and Extend to kinda clean everything up. So I'm gonna clean this one up with that and this one with that, remember to always pick the side you wanna keep.
I'll do ZP for Zoom Previous, and I wanna keep this side and this side, see how that trims off that small little piece. I wanna keep this line and this side, that trims off this over here. This side and this side, trims off that little piece and the long line there, and then finally this to this to give me that ceiling shape. When I click Finish, it will create the ceiling shape and, again, if we look at it in section, you can see that that one is a little bit higher up and it's a little bit thicker because it's using the drywall type instead of the acoustical ceiling type.
Okay. So, those are my ceiling elements now. Now I wanna talk about how to make adjustments to some of the objects. Notice that if you move your mouse into the space, it actually highlights the individual lines that make up the pattern that's on that ceiling plane. Now, that actually is just a model pattern that's being applied via the material of that ceiling. And what's really interesting about this is you can select those lines, and that will activate the Move and Rotate commands.
So in this case, let's say I wanted this office to have the tiles going the other way. All I have to do is click my Rotate tool and I'm going to click the small dot here and snap it right to the center of the room there, and then I'm gonna click here and type 90 to rotate that ceiling 90 degrees. And notice how even though I only had one line selected, it still rotates the entire pattern. Okay, so that's the way these pattern modifications work, is you can select any line that's convenient, but moving or rotating will affect the whole pattern.
Let's see another example over here. Let me zoom in on a couple of these offices, and probably the easiest way to decide whether or not I need to move or rotate the pattern is to actually add some light fixtures, because usually that's when you make those decisions. Now to add light fixtures, you just use the Component tool. So back on Architecture, I'll click on Component, open up my type selector here, and look for a light fixture within the list, or you can actually type right here at the top and I'll just type in the word "light," and that will shorten the list to only the families that contain "light" in the name.
And here's a troffer light, and I'll choose a two-by-four two-lamp fixture. Notice that I get the circle with the line through it. The light fixture is similar to doors and windows in the sense that it is a hosted element. And specifically in this case, if you look at the tool tip that appeared onscreen or at the status bar at the bottom left corner of the screen, it says click on a ceiling to place this instance. So as soon as I move into the room that has a ceiling, it will see the ceiling and host to that element.
Now you could try and get it to snap exactly to the grid, and usually it'll do a pretty good job of doing that, but often what I'll do is actually just kinda place it randomly, cancel the command, go to Modify, click my Align command, pick an edge of the ceiling, and align it, pick an edge of the ceiling and align it. Now, whichever method you prefer is entirely up to you. Now I'm gonna select both of these lights with my Control key, go to my Copy command, and copy them over here, to this location, and now you can see the problem is that they don't line up correctly in the space.
Well, let me zoom out just a touch, and before I deal with that, I'm going to make a window selection to get all four of those lights. I do wanna verify over here that it says Lighting Fixtures (4), because if the quantity says something else then I'll wanna investigate that first before copying so that I don't accidentally copy too many things, but four is what I wanted. Pick my start point, pick a new point, and then do one more copy, start point, and new point. As you can see, we obviously need to make some adjustments here.
Now, for example, in this room here, maybe I want to shift them a little bit so that they're centered a little better. Well, once again, if you select one of the grid lines, instead of rotating this time, I'm gonna do Move, and I'm gonna click any start point and I'm gonna start moving in the direction that I wanna go, and I'll just type in one, which is half the size of the tile. And that will shift the pattern by one foot, and it will take the light fixtures with it, which means that I can do the same thing in the other direction, go to Move, and it looks like if I go maybe about a foot and a half here, it will do the trick, and that shifts it over and moves all of the lights with it.
Now that I've got these centered the way I want, I can use my Align command and say, let's line up the tiles in these opposite rooms. And as you can see that once you kind of get in the swing of things, it'll go fairly quickly where you can start placing the light fixtures and then adjusting all the tile patterns to match. So the simplest way to create ceilings is to use the automatic option that works really well when you have an enclosed space of walls, but in cases where you need a more complex shape, you can switch to sketch-based tools. And then to decide how you want your grid patterns to be oriented, you can use Move and Copy tools based on the position of the light fixtures that you've placed within the space.
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.
