Chapter 6 • Floors 254 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. FIGURE 6.16 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. Placing a Floor Slab 255 TIP 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. FIGURE 6.17 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. Chapter 6 • Floors 256 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. FIGURE 6.18 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. Building a Floor by Layers 257 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). FIGURE 6.19 Duplicating the existing floor Chapter 6 • Floors 258 7. Click OK. 8. In the Structure row, click the Edit button, as shown in Figure 6.20. FIGURE 6.20 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. FIGURE 6.21 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 Building a Floor by Layers 259 other available functions. Click the drop box arrow and select Finish 1 [4] (see Figure 6.22). FIGURE 6.22 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. FIGURE 6.23 The completed layers for the floor system Chapter 6 • Floors 260 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. FIGURE 6.24 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).

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. FIGURE 6.27 Click Yes to attach the walls to the floor’s bottom. FIGURE 6.28 Click Yes if you want to cut overlapping volumes out of the exterior walls. NOTE 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. Building a Floor by Layers 263 FIGURE 6.29 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. FIGURE 6.30 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. . with.
