using trim to clean up the sketch

Now that the lines are placed, you need to make sure you don’t have any gaps

or overlaps And you do To fix these gaps and overlaps, you will use the basic modify commands from the previous chapter

The east wall has a giant gap at the bottom and an overlap at the top The command you need to use here is the Trim command:

1 Pick the Trim/Extend Single Element button from the Modify panel

as shown at the top of Figure 6.16, and click the portions of the two lines you want to keep This will remove the excess from the corner

2 With the corners successfully trimmed, click Finish Edit Mode.

F i g u R e 6 1 6 Picking the magenta lines in the numbered order illustrated

in the figure

When Revit allows you to finish the sketch, your west wing and corridor should have a slab underneath it, as shown in Figure 6.17



When you pick the

west wall of the

corridor, you may

find that revit just

will not let you pick

the opposite face of

the wall this is OK

pick the inside face

of the wall, and then

move the magenta

line to the opposite

face of the wall

by using the flip

arrows.

T I P hopefully you do not get an error stating that lines are

overlap-ping If you do, keep going with the trim/extend Single element command

also, you may need to investigate each corner You may also want to

con-sider that you have accidentally placed double lines along a wall

F i g u R e 6 1 7 The two slabs under the west wing and the corridor

It is time to add a slab under the east wing Go ahead and try it on your own

Only look at these directions if you get lost!

1 Zoom in on the east wing.

2 On the Home tab, select the Floor button.

3 In the Modify | Create Floor Boundary tab, click the Pick Walls button.

4 Pick the exterior walls of the east wing.

5 Trim any gaps or overlaps that may occur in the corners Also, pay

special attention to the radial entry It can be tricky

6 Click Finish Edit Mode.

Your east wing should look like Figure 6.18, which is looking at the bottom of

the building from a 3D view

O

You can still access most of the basic editing commands such as trim, Split element, and Offset while you create the floor boundary.

Now that we have a nice slab on the first floor, we need to add some more slabs

to the rest of the levels The trick with the slabs on upper levels is that they need

to extend into the core of the walls This is where Revit can get sticky Follow along with the next section, and let’s work out this issue together

F i g u R e 6 1 8 Adding a slab to the east wing

Building a Floor by Layers

As mentioned in the previous section, the term layer does not equate to AutoCAD’s layer It does, however, equate to layers of materials used to design a floor system

In Revit Architecture, when you create a floor system you can do it with the mind-set of how a floor is actually constructed You can also specify which material in the floor will stop at an exterior wall and which will pass through to the core

In this section, you will build on your experience of creating a floor Now that

the concrete slab is in place, we will start adding materials to create a floor finish

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 6 and find the file called

NER-20.rvt

Your objective is to create a floor system with a structure and a finish material

You will also design the floor to interrupt the exterior framing, while letting the

brick façade pass from grade to parapet Let’s get started:

1 In the Project Browser, go to the Level 2 floor plan (Remember not

to go to the Level 2 ceiling plan.)

2 In the View Control bar (located at the bottom of the view window),

be sure that the detail level is set to Fine

3 On the Home tab, click the Floor button.

4 In the Properties dialog, click the Edit Type button.

5 Click the Duplicate button.

6 Call the new floor 6″ concrete with 1″ Terrazzo (see Figure 6.19).

8 In the Structure row, click the Edit button, as shown in Figure 6.20.

F i g u R e 6 2 0 Clicking the Edit button in the Structure row

You are now in the Edit Assembly dialog, as you were in the previous procedure The objective now is to add 1″ terrazzo flooring to the top of the 6″ of concrete

Adding a Layer

Now it’s time to add the additional material To do so, you need to understand how the Edit Assembly dialog is broken down Since we want to add a material

to the top of the slab, we need to click above the concrete and insert a new layer,

as follows:

1 In the Layers field, you will see three rows Each of the three rows has

a corresponding number Click on the number 1 This is the top row that reads Core Boundary Layers Above (see Figure 6.21)

2 Underneath the Layers field, you will see an Insert button, as shown

in Figure 6.21 Click it

F i g u R e 6 2 1 Inserting a new layer for the terrazzo

3 The new layer is added You will now see that the field is divided into

columns The first column is the Function column Currently it says that the Function is Structure This cell is a drop box containing the

other available functions Click the drop box arrow and select Finish

1 [4] (see Figure 6.22)

F i g u R e 6 2 2 Choosing a layer function

4 Click into the Material cell.

5 Click the […] button.

6 In the Materials dialog, select Terrazzo in the Materials list to the left

Click OK

7 In the Thickness column, enter 1″ Make sure you are typing 1 inch,

not 1 foot (see Figure 6.23)

8 To the far right of the rows in the Layers field are Variable checkboxes

Click Variable for the Structure row, as shown in Figure 6.23 This

will enable you to slope the slab if need be Only the layer that is set to

be variable will actually slope Any layer that is on top of this variable

layer will be pitched

9 At the bottom of the Edit Assembly dialog is a Preview button Click

it After you do, you can see a graphic preview of your floor in a sec-tional view, as shown in Figure 6.24

10 Click OK twice to get back to the model.

F i g u R e 6 2 4 You can see a preview of the floor in section as it is being built.

Great job You now have a floor with a material on it! The next step is to place

it into the model

With the new floor created, you can now place it into the model Remember that you are in the second floor When you place the slab, you want it to extend directly into the wall core To do so, follow along:

1 Click the Pick Walls button on the Draw panel You will pick every

exterior wall in the east wing except for the radial wall

2 Start picking walls, as shown in Figure 6.25 Do not pick the radial

wall at the east entry

3 On the Draw panel, select the Line button.

4 Draw a line from the endpoint of the magenta line at the north wall of

the east entry (see “1” in Figure 6.26), to the endpoint of the magenta line in the south wall (see “2” in Figure 6.26)

5 On the Modify | Create Floor Boundary tab, click Finish Edit Mode.

6 Revit will start asking you questions First Revit will ask you if you

want to attach the walls that go up to Level 2 to the bottom of the

floor You do want to do this; this will cut the walls down to meet the

bottom of the floor Any change in the floor’s thickness will alter the tops of the wall Click Yes, as shown in Figure 6.27

7 The next message pertains to the exterior walls Revit asks if you

would like to cut the section out of the walls where the slab is inter-secting In this case you do, so click Yes in the message box, as shown

in Figure 6.28

F i g u R e 6 2 7 Click Yes to attach the walls to the floor’s bottom.

F i g u R e 6 2 8 Click Yes if you want to cut overlapping volumes out of the

exterior walls.

N O T E as these messages come up, revit usually does a good job of highlighting the items in the model it is addressing in these messages Get into the habit of looking past the messages to see what items in the model are being highlighted

With the second floor in place, you can now add it to the floors above To do so, you can use the Copy/Paste Aligned feature you used in Chapter 3, “Creating Views.” Try to do this on your own If you don’t remember how, or skipped Chapter 3, follow these steps:

1 Select the floor in Level 2 (It is easiest to select the floor at the east edge.)

2 On the Modify | Floors tab, click the Copy To Clipboard button on the

Clipboard panel, as shown in Figure 6.29

F i g u R e 6 2 9 Clicking the Copy To Clipboard button

3 Go to the default 3D view, as shown in Figure 6.30.

4 From the Paste fly-out on the Clipboard panel, click Paste ➢ Aligned

To Selected Levels as shown in Figure 6.30

F i g u R e 6 3 0 Using Paste Aligned To Selected Levels

5 The Select Levels dialog appears, where you will choose which levels

you want to paste your floor Choose Levels 3, 4, and 5, as shown in

Figure 6.31

6 Click OK The floors will be pasted to the specified levels, as shown in

Figure 6.32

O

a good indication that you have suc-cessfully copied the floor to the clipboard

is that the paste icon directly to the right

of the Copy icon will become activated.
