4 Now that the floor is selected, notice on the Modify | Floors tab that you
have several choices Click the Add Split Line button (see Figure 6.46)
5 Draw lines along the finished inside face of the lavatory, as shown in
Figure 6.46 As always, there can be no gaps or overlaps
N O T E Yes, it is true that the snapping feature is tedious at best when you’re using the Split Line command Be patient You will need to basically get as close to the face of the wall as possible before you pick the point this
is one case where you will need to eyeball the exact pick points
F i g u R e 6 4 6 Drawing a split frame around the inside of the lavatory
With the split lines drawn, you have isolated the lavatory area from the rest of the floor Now you can pitch the floor in this area without affecting the rest of the floor The pitch will extend only as far as the split lines
To create a drop in the floor, follow these steps:
1 On the Home tab, select the Model Lines button, as shown in
Figure 6.47
2 Draw the line from the midpoint of the restroom’s right wall, to the
left 3′–0″, as shown in Figure 6.47

3 Press Esc twice.
4 Select the floor (Remember the Filter dialog.)
5 On the Modify | Floors tab, select the Add Point button, as shown in
Figure 6.48
6 Pick the endpoint of the line you just drew, as shown in Figure 6.48.
7 Press Esc once This will put you in the Modify Sub Elements mode
You will know you are in this mode by the icon next to your pointer,
as shown in Figure 6.49
8 Pick the point you just placed into the model It will turn red, and a
blue elevation will appear As you know, any blue item is modifiable
Click the 0′–0″ value, and change it to –1″ (negative one inch)
9 Press Enter Revit will drop that area of the floor and add the slope
lines as if you drafted them in
10 Press Esc twice.
11 Delete the line you drew as a guideline.

Now that you have experience in creating and placing floors, as well as being able to pitch a floor in a specific area, it is time to look at one more item: shaft openings
Ca n i er a s e th i s a n d sta r t ov e r?
Often you may just need to clear the entire slab and start again You can
do this simply by selecting the floor and clicking the Reset Shape button on the Options bar, as shown in the following image:
creating shaft openings
To create a shaft opening, you just create a void through your model This void, however, can conform to walls that are set in the model The elevator shaft walls, for instance, will define the outside edge of our shaft opening You may notice that the floors we added to the model are indiscriminately running unin-terrupted straight through the shafts We need to void the floor Also, the good thing about creating a shaft opening is that if we create another floor, the shaft will be cut out automatically
To get started, open the file you have been following along with If you did not
complete the previous procedure, go to the book’s web page at www.sybex.com/ go/revit2011ner From there you can browse to Chapter 6 and find the file called
NER-21.rvt
First, we need to create two more levels We need a subterranean level (T.O Footing) and a penthouse level to extend the elevator shaft up through:
1 In the Project Browser, go to the South elevation.
Trang 6C r e a t i n g S h a f t O p e n i n g s 2 7 9
2 On the Datum panel of the Home tab, click the Level button.
3 On the Draw panel, click the Pick Lines icon, and set an offset of
10′–0″ (see Figure 6.52)
4 Hover your cursor over Level 1 Make sure the alignment line is
below Level 1 When you see the alignment line, pick Level 1 You
now have a new level at –10′–0″
5 Click the Modify button on the Select panel to terminate the command.
(see Figure 6.52)
7 Click Yes when Revit prompts you to rename corresponding views.
F i g u R e 6 5 2 Adding a new Top Of Footing level
The next step is to select the CMU elevator shaft walls and modify their
prop-erties so that the bottoms are extended down to the top of the footing and the
tops are extended to the penthouse level:
1 Go to a 3D view.

2 Select all of the CMU walls Remember to press and hold the Ctrl key
as you select the walls
3 In the Properties dialog, under the Constraints category, set Base
Constraint to T.O Footing, as shown in Figure 6.53
4 Click OK.
F i g u R e 6 5 3 In the Properties dialog, change Base Constraint to T.O Footing.
With the bottom established at the correct level, it is time to add the shaft:
1 Go to the Level 1 floor plan (note that it does not matter which floor
you are actually in when you place a shaft opening)
2 On the Home tab, click the Shaft Opening button in the Opening
panel as shown in Figure 6.54
3 On the Modify | Create Shaft Opening Sketch tab, click Pick Walls, as
shown in Figure 6.55
4 Pick the walls shown in Figure 6.55 Notice that you can have more
than one shaft opening in the same command
5 Use the Line button on the Draw panel to draw the line across the
inside face of the exterior wall
6 Use the Trim command to clean up any corners (see Figure 6.55).
to select all of the
CMU walls, you can
simply select only
one, right-click, and
then click Select all
Instances Be
care-ful, though; if there
are other CMU walls
of the same type in
the model, they will
become selected
as well.

Now that the perimeter has been established, it is time to establish which floors this opening will extend to Just because we picked the CMU walls, this does not mean that a base and a top height have been established
1 In the Properties dialog , make sure Shaft Openings is selected, as
shown in Figure 6.56
2 In the Properties dialog, set Base Constraint to T.O Footing.
3 Set Top Constraint to Up To Level: Roof.
4 Set Top Offset to –1′–0″ (this keeps the roof from having two giant square holes in it)
5 Click Apply Figure 6.56 shows the settings.
F i g u R e 6 5 6 Setting the properties of the shaft opening
6 On the Modify | Create Shaft Opening Sketch tab, click the Symbolic
Line button This will allow you to sketch an opening graphic into the shaft
7 Draw an “X” in both openings, as shown in Figure 6.57.
8 Click Finish Edit Mode.

Notice the floor is now voided from the openings Go to a 3D view and look
down the shafts They are wide open, as shown in Figure 6.58
N O T E a shaft opening will only void floors and roofs any other
geometry such as walls and structural framing will not be voided You need
to modify these elements on a piece-by-piece basis
F i g u R e 6 5 7 You can add any “drafting” symbolic lines you deem necessary.
Now that you know how to pitch floors, you can begin using Revit for its unique
capabilities Also, you are better prepared to move into the next chapter, which
focuses on creating roofs
