creating ceilings
Placing a ceiling is quite easy; the hard part is finding the view in which to do it
As you have probably noticed, the Project Browser is broken down into catego-ries The categories for plans are Floor Plans and Ceiling Plans Whereas floor plans show the views standing at that level looking down, ceiling plans show the view standing at that level looking up In Revit, you are looking at a true reflected ceiling plan
To begin, open the file you have been following along with If you did not
complete the previous chapter, go to the book’s web page at www.sybex.com/go/ revit2011ner From there you can browse to Chapter 9 and find the file called
NER-25.rvt
1 Go to the Level 1 ceiling plan, as shown in Figure 9.1 (remember, this
is a ceiling plan, not a floor plan)
F i g u R e 9 1 The Ceiling Plan category
2 On the Home tab, click the Ceiling button, as shown in Figure 9.2.
3 With the Ceiling command active, select the Change Element Type
menu in the Properties dialog You should see the same ceiling types
as shown in Figure 9.3
4 Choose 2′× 4′ ACT System from the Type Selector
5 Hover your mouse over the room shown in Figure 9.4 Notice the
perimeter is outlined in red This indicates that the ceiling has found
at least four walls you can use as a layout
6 When you see the red outline, pick a point in the middle of the room
Your ceiling should now look like Figure 9.5

There will be times when you do not have the system families you need to
carry out the task at hand Ceiling types seem to be the number 1 system
family that falls victim to being inadvertently deleted from a model before
it gets used If you find that you do not have the ceiling types shown in
Figure 9.3, do the following:
1 On the Revit Application panel, choose New ➢ Project
2 In the New Project dialog, click OK to start a new project using the
default template
3 On the View tab, click Switch Windows in the Windows panel, and
select the Reflected Ceiling Plan from the fly-out to get back to the
No Experienced Required project
4 On the Manage tab, click Transfer Project Standards in the Settings panel.
5 In the Select Items To Copy dialog (see the following graphic), click the
Check None button
6 Click Ceiling Types.
7 Click OK.

That was just too easy! Too good to be true, right? All right, it is You always
have to make adjustments to this type of item You probably noticed that you had no control over which direction the grids were running Also, we have no clue how high these ceilings are It is time to start modifying the ceilings
Modifying ceiling grids
To be honest, a ceiling consists of nothing more than a basic hatch pattern applied
to a material Actually, everything in Revit is a basic hatch pattern applied to a material That sure does make it easy to understand!
The one unique thing about hatch patterns in Revit is that you can modify them on screen That means you can move and rotate a hatch pattern That also means you can move and rotate a grid pattern Let’s give it a shot:
1 Press Esc to cancel the command you may be in.
2 Pick the ceiling grid line, as shown in Figure 9.7 (Make sure you’re
zoomed in close enough to make the Rotate command active.)
3 On the Modify | Ceilings tab, click the Rotate button, as shown in
Figure 9.7
4 Rotate the grid 45° by using the two-pick method, as shown in
Figure 9.8
F i g u R e 9 7 Select one of the grids and click the Rotate button.

F i g u R e 9 8 The Rotate process
Your ceiling should now look like Figure 9.9
F i g u R e 9 9 The ceiling at a 45° angle
Now that the ceilings are in, let’s look at the ceiling’s properties before we go
too far As a matter of fact, it is a good idea to investigate the ceiling’s properties
before you place it in the model
rotating a ceil-ing grid is a good example of the hatch functionality in revit You can rotate and move hatch patterns whether they are ceilings, brick, or any other pattern you need to manipulate.

ceiling element Properties
As I mentioned earlier, ceilings are set up in a similar fashion as floors So, it stands
to reason we will see many similar properties
Before we get started, let’s make some modifications to the west wing The objec-tive of this procedure is to add a hard ceiling with metal framing, gypsum, and a
1 Go to a 3D view of the model.
2 Select the sloped roof that covers the west wing, as shown in Figure 9.10.
3 Right-click.
4 Select Override Graphics In View ➢ By Element (see Figure 9.10)
F i g u R e 9 1 0 Selecting the roof, and right-clicking
5 In the View-Specific Element Graphics dialog, click the Transparent
button in the upper-right corner, as shown in Figure 9.11
6 Click OK The roof is now transparent.
F i g u R e 9 1 1 The View-Specific Element Graphics dialog
Trang 8C r e a t i n g C e i l i n g s 3 9 1
We made the roof transparent because some of the walls have to be attached
to the roof It is much easier to attach the walls in a 3D view But to do so, we
need to see the walls that we will be working on:
1 Select the wall shown in Figure 9.12.
2 On the Modify | Walls tab, select the Attach Top/Base button.
3 Pick the roof.
Your wall should look like Figure 9.12
F i g u R e 9 1 2 Attaching the wall to the roof
The next step is to constrain the partition walls in this area to Level 3 The
ceil-ings we will add to these rooms will be much higher than the rest of the building
1 While still in a 3D view, select the partitions shown in Figure 9.13.
2 In the Properties dialog, set the Top constraint to Up To Level: Level 3.
3 The walls are now constrained to Level 3.
4 Go to Level 1 under Ceiling Plans (if it is not open already).
The next procedure is a tad off-the-beaten-path but it fits squarely within this
process Because we have specified the walls in this area to be of a greater height
than the rest of the walls in the model, we are obviously adding ceilings higher

F i g u R e 9 1 3 Selecting the partitions
creating a Plan Region
Sometimes you will need to set your view range in a specific area that differs from the view range in the plan as a whole In this example, we will add a ceil-ing at 14′–6″ above the finish floor If we do this with the current View Range settings, Revit will not display the ceiling If you modify the View Range for the entire view, you will see the 14′–6″ ceilings, but you will not see the regular
8′–0″ ceilings in the rest of the building in that view
In the following procedure we will create a region where the view range is dif-ferent from the view range in the Level 1 ceiling plan:
1 In the Project Browser, make sure you are in the Level 1 Ceiling Plan.
W A R N I N G Double-check to be absolutely sure you are not in a floor plan You want to be in the ceiling plan!
2 Zoom into the west wing.
3 On the View tab, select the Plan Views ➢ Plan Region button, as shown in Figure 9.14
4 On the Draw panel, click the Rectangle button, as shown in
Figure 9.15
5 Pick a rectangle around the north portion of the west wing, as shown
in Figure 9.15

F i g u R e 9 1 4 The Plan Region button on the Create panel of the View tab
F i g u R e 9 1 5 Defining the limits of the plan region by drawing a rectangle
around a specific area
Notice that the View tab has now switched to the Modify | Create Plan Region
Boundary tab We now need to define the view range for this region:
1 In the Properties dialog, click the Edit button in the View Range row.
2 In the View Range dialog, set the Top setting to Level 3.
3 Set Cut Plane Offset to 14′–6″
4 Set Bottom Offset to 7′–6″
5 Set View Depth Level to Level 2 with an Offset value of 16′–0″ (see
Figure 9.16)
