Chapter 10 • Stairs, Ramps, and Railings 464 4. For the first point of the arc, pick the midpoint of the landing, as shown in Figure 10.36. 5. Move your cursor down and at 135° from the first point picked. 6. Extend your cursor 11′–0″, as shown in Figure 10.36, and then click to set the second point. 7. To form the arc, move your cursor to the right until the radius snaps into place. When it does, pick the point, as shown in Figure 10.37. FIGURE 10.36 With the Start-End-Radius Arc, first start at the midpoint of the landing, then go southwest at an angle of 135° and a distance of 11 ′–0″. FIGURE 10.37 Picking the third point to form the arc. It will be tangent upon the first two points you picked. Creating a Winding Staircase 465 8. Press Esc. 9. On the Draw panel, click the Pick Lines icon. 10. On the Options bar, add an increment of 2 ′–0″ to the Offset field (see Figure 10.38). 11. Offset the center arc to the right, then to the left, forming a 4 ′–0″ overall winder, as shown in Figure 10.38. 12. Press Esc. 13. Click the Line tool, make sure Offset is set to 0′0″, and then draw a straight line at each end of the arcs, as shown in Figure 10.39. FIGURE 10.38 Adding two more arcs based on the centerline of the first Okay, take a breather. Compare the examples in the book to what you have. Are we close? If not, go back and investigate. NOTE Get used to this drafting thing; it is still very much a part of BIM, regardless of whether people say you can’t draft in Revit! Chapter 10 • Stairs, Ramps, and Railings 466 FIGURE 10.39 Adding two straight lines at each end of the arcs The next step is to make an array of the straight lines we just added. These lines will wind up being our guidelines for our risers. 1. Press Esc, and then select the smaller arc, as shown in Figure 10.40. FIGURE 10.40 Selecting the smaller arc 2. Make sure the Properties dialog is active. 3. In the Properties dialog, check Center Mark Visible. 4. Select the line at the left end of the arcs, as shown in Figure 10.41. 5. Click the Array button on the Modify | Lines tab, as shown in Figure 10.41. 6. On the Options bar, be sure that Radial is selected. 7. Make sure Group And Associate is checked. Creating a Winding Staircase 467 8. Type 18 for the number. 9. Click Move To: Last on the Options bar. (Remember, we aren’t actu- ally moving this line; we are simply copying to last.) 10. When these options are set, pick and drag the blue icon to the center point you turned on earlier (see Figure 10.41). 11. Pick a point along the first line (the one on the bottom left). 12. Pick the second point along the upper-right line. FIGURE 10.41 Arraying the line to create your own treads Your array should now be complete. Compare your linework to Figure 10.42. FIGURE 10.42 The stairs are taking shape. Chapter 10 • Stairs, Ramps, and Railings 468 It’s time to start modeling the stairs. This procedure will be nothing more than tracing the lines you have already added to the model. To do this, we are going to utilize the tools available that we have not touched in the previous staircase, as follows: 1. On the Home tab, click the Stairs button. 2. In the Properties dialog, change Base Level to Level 1. 3. Change Top Level to Level 2. 4. Click Edit Type. 5. Click Duplicate. 6. Call the stairs Corridor Entry Stairs. 7. Click OK. 8. For Tread Material, click in the field where it says <By Category>. 9. You will see a […] button. Click it. 10. Choose Wood - Cherry for the Tread Material. 11. For Riser Material, do the same. 12. For Stringer Material, select Wood - Mahogany (see Figure 10.43). FIGURE 10.43 Customizing the stairs Creating a Winding Staircase 469 13. Under the Treads category, select Front, Left And Right for Nosing Profile. 14. In the Stringers category, select Match Level for Trim Stringers At Top (see Figure 10.43). 15. Click OK to get back to the model. It’s now time to add the stairs to the model. To do this, we will first sketch the boundary: 1. On the Modify | Create Stairs Sketch tab, click the Boundary button, as shown in Figure 10.44. 2. On the Draw panel, click the Pick Lines icon. 3. Pick the two arcs defining the outside of the stairs. You will see green arcs copied directly on top of them. FIGURE 10.44 Click the Boundary button. 4. On the Draw panel, click the Riser button, as shown in Figure 10.45. FIGURE 10.45 Click the Riser button. 5. On the Draw panel, click the Pick Lines icon. 6. Pick all of the lines you arrayed. This includes the bottom and the top lines (see Figure 10.46). 7. Click Finish Edit Mode on the Mode panel. Chapter 10 • Stairs, Ramps, and Railings 470 FIGURE 10.46 Picking the detail lines to lay over the stair components With the stairs roughed in, we need to get a better look at them. If we use the default 3D view, we need to turn off way too many items to see our stairs. Let’s add a perspective view just to see what’s going on here! If you are confident in adding your own perspective view, go ahead and put one in, and name it East Entry from Corridor. If not, follow along with the procedure: 1. In the Project Browser, go to the Level 1 floor plan. 2. On the View tab, click the 3D View ➢ Camera button. 3. Pick the first point shown in Figure 10.47. 4. Pick the second point shown in Figure 10.47. 5. In the Project Browser, find the new perspective view, and rename it to East Entry from Corridor. 6. In the Perspective view, turn on Shading With Edges (it is located at the View Control bar at the bottom of the view). Now that we have a perspective on our stairs, we can see multiple issues with the railing. The first, more prominent issue is that the railings seem to be float- ing. This occurs when the stringers are switched from closed to open. Revit still thinks there is a stringer underneath the railings. We will need to move the rail- ings in 2 ″ to fix this problem. Creating a Winding Staircase 471 FIGURE 10.47 Adding the perspective view Making Railing Adjustments Yes, we have been making railing adjustments this entire chapter. Get used to constantly having to do this for each unique situation. This staircase requires us to add some posts back into the railing so it can stop and end at the stringer. But first let’s move the railing back onto the actual treads: 1. Go to the Level 2 floor plan. 2. Select the top railing, as shown in Figure 10.48. 3. On the Modify | Railings tab, click Edit Path. 4. Click the Offset button on the Modify panel, as shown in Figure 10.48. 5. In the Offset field in the Options bar, type 2”. 6. Deselect the Copy option. 7. Offset the railing into the stairs 2 ″, as shown in Figure 10.48. Chapter 10 • Stairs, Ramps, and Railings 472 FIGURE 10.48 Offsetting the railing in 2″ 8. Click Finish Edit Mode. 9. Select the other railing. 10. Click the Edit Path button on the Modify | Railings tab. 11. Offset the railing in 2 ″. 12. Click Finish Sketch Mode. Since these railings will not extend past the stringers, it is OK to add posts back to the beginning and the ends of the railings: 1. Select both railings. 2. In the Change Element Type menu, select Railing : Handrail - Pipe. 3. Go to the East Entry from Corridor view. Does your stair and railing system look like Figure 10.49? Creating a Winding Staircase 473 FIGURE 10.49 The almost completed stairs The next series of steps will involve mirroring the stairs to the other side of the landing. Then, of course, we need to add a landing railing so people don’t just walk out the door and off the ledge. 1. Go to the Level 2 floor plan in the Project Browser. 2. Select the stairs and the railings. NOTE To select only the stairs and the railings, you can pick a win- dow around the entire set of lines, groups, railings, and stairs. From there, you can click the Filter button on the Ribbon, and select only Stairs And Railings. 3. On the Modify | Multi-Select tab, click the Mirror ➢ Pick Mirror Axis button, as shown in Figure 10.50. 4. Pick the center reference plane (I told you this thing would come in handy). Your stairs are now mirrored to the other side of the landing, as shown in Figure 10.50. . Are we close? If not, go back and investigate.
