To do so, go to the Level 1 West plan and select the curtain wall. After you select the wall, you can click the little double arrow in the middle of the wall as shown in the following graphic. This will flip the direction of the entire curtain wall. With the panels in place, it is time to start filling in the mullions—which brings us to our next step: adding mullions to the grid. Adding Mullions to the Grid The next logical step is to create the mullions that will be attached to the grid we just added. Since we have a few areas where there should not be any mullions, the job becomes more tedious. The next example could go one of two ways. One procedure will involve adding mullions piece by piece, whereas the other procedure will allow you to add mul- lions all at once and then delete the mullions you do not need. This procedure will take the latter approach; we’ll add the mullions all at once and then remove the superfluous mullions. 1. On the Build panel of the Home tab, click the Mullion button, as shown in Figure 16.35. 2. In the Properties dialog, choose Rectangular Mullion: 2.5 ″ × 5″ Rectangular. 3. Pick the grid above the door, as shown in Figure 16.36. 4. Press Esc. Creating Curtain Walls 755 FIGURE 16.35 Click the Mullion button on the Home tab. 5. Click the Mullion button again. 6. On the Placement panel, click All Grid Lines. 7. Pick anywhere on the grid. The mullions have been added to the entire system. 8. Press Esc. FIGURE 16.36 Place the 2.5″ × 5″ rectangular mullion above the door. Chapter 16 • Advanced Wall Topics 756 With the mullions added, we have actually gone too far! There is now an alu- minum extrusion that separates the CMU from the adjacent brick. The objective of the next procedure is to remove these pieces of mullion. 1. Zoom into an area where the CMU meets the brick, as shown in Figure 16.37. 2. Select the small mullion piece that lies between the brick and the CMU. (You will have to press the Tab key several times to accomplish this.) 3. With the mullion selected, notice you can either modify the join (as shown in Figure 16.37) or you can press the Delete key and remove the mullion. In this case, delete the mullion. Repeat the procedure for other similar areas. FIGURE 16.37 Selecting the mullion So, what have we accomplished here? Well, we have embedded a predefined curtain wall to a radial profile, and we have added a curtain system to a giant glass panel by hand. The only thing left to do is to apply a curtain wall to a slop- ing surface. Adding a Wall to a Massing Object Sometimes in architecture, artistic expression is required on a project, such as curved and laterally sloping walls that cannot be accomplished using straight, linear components. Most of the time some form of expression will be added to a project. We need to be able to deal with that in Revit, and we can! Adding a Wall to a Massing Object 757 The process involved in adding a sloped wall is to first create a massing object, and then apply the wall to the face of that object. The objective of the next pro- cedure is to create a mass along the south entrance of the building. 1. In the Project Browser, open the West Corridor Section. 2. In the West Corridor Section view, turn on the crop region, as shown in Figure 16.38. 3. Select the crop region as shown in Figure 16.39. 4. In the Properties dialog, scroll down to the Far Clipping row. 5. Click the Clip Without Line button, as shown in Figure 16.40. 6. In the Far Clipping dialog, click the No Clip button (see Figure 16.40). 7. Click OK. FIGURE 16.38 Turning on the crop region and adjusting the line Now that the view is set up, we can take full advantage. The objective of the next exercise is to place a mass. After we place the mass, we can add a wall and a roof to it. 1. On the Massing & Site tab, click the In-Place Mass button, as shown in Figure 16.41. Chapter 16 • Advanced Wall Topics 758 FIGURE 16.39 The crop region is selected. You can tell by the grips and the break icons. FIGURE 16.40 Adjusting the view’s clipping 2. If you get the Show Mass Enabled dialog, just click Close. 3. Name the mass South West Entry and click OK. 4. On the Draw panel, click the Start-End-Radius Arc button, as shown near the top left in Figure 16.42. 5. You will be prompted to pick a work plane. Pick the far wall, as shown in Figure 16.42.

On the Draw panel, click the Line button, and draw three lines form- ing a box, as shown in Figure 16.43. Chapter 16 • Advanced Wall Topics 760 FIGURE 16.43 Adding the 3D mass 8. On the Quick Access bar, click the Default 3D View button. 9. Zoom in on the perimeter you have sketched and select it, as shown in Figure 16.44. FIGURE 16.44 The Create Form button Adding a Wall to a Massing Object 761 10. On the Form panel of the Modify | Lines tab, click the Create Form button, as shown in Figure 16.44. 11. Pick (left-click) and drag the right-facing arrow so that the mass is in alignment with the corner of the building, as shown in Figure 16.45. FIGURE 16.45 Dragging the extrusion to the right 12. Pick the top, front edge of the mass. 13. Click the arrow facing up and drag the edge down, causing a slope. You can eyeball the distance, then type 18’ 4” in the temporary dimension, as shown in Figure 16.46. 14. Click Finish Mass. 15. On the Model By Face panel, click the Roof button, as shown in Figure 16.47. 16. Pick the top of the mass, as shown in Figure 16.48. 17. After you pick the top of the mass, click the Create Roof button, as shown in Figure 16.48. 18. Press Esc. 19. On the Massing & Site tab, click the Curtain System button.

Change Curtain Panel to System Panel : Glazed. 25. Set Join Condition to Border and Grid 1 Continuous. For the Grid 1 Pattern, set Layout to Maximum Spacing. 26. Set Spacing to 3′ 0″. 27. Repeat the layout and the grid spacing for the Grid 2 Pattern. 28. Change all of the mullions to use Rectangular Mullion : 2.5 ″ × 5″ rectangular (see Figure 16.49). 29. Click OK to get back to the model. The next step is to apply the curtain system to the face(s) of the mass. The objective of the next series of steps is to apply the new curtain system to the front and the left side of the mass. 1. Pick the front face of the mass. 2. Pick the left face of the mass. 3. Click Create System. Your walls should resemble Figure 16.50. . to a slop- ing surface.
