Chapter 19 • Rendering and Presentation 834 5. Scroll down to the bottom of the list and locate the lights Sconce Light - Uplight : 60W - 120V. Select all of them, as shown in Figure 19.12. 6. Click the Move To Group button under Fixture Options. FIGURE 19.10 Adding a lighting group FIGURE 19.11 Creating a new group Creating an Exterior Rendering 835 FIGURE 19.12 Moving the selected lights to the new group 7. Choose the Interior Lighting Northwest group in the Light Groups dialog and click OK. 8. Click OK to close the dialog. 9. In the Project Browser, go to the Level 1 ceiling plan. 10. Select one of the exterior lights. 11. On the Options bar, click the Light Groups menu, and select Edit/New. 12. Create a new group called Exterior Corridor. 13. Locate the exterior wall pack lights and add them to the group. 14. Click OK. 15. Go back to the Level 1 floor plan. 16. Add the same sconce lights to the interior of the corridor at each cor- ner, and at the ends of the walls. 17. Create a new lighting group called Corridor Interior, and add the cor- ridor lights to the group. You now have three lighting groups. 18. In the Project Browser, go to the Rendering View Corridor view. 19. On the View Control bar, click the Sun Path button (it is the picture of the sun with the small red x), and click Sun Settings. Chapter 19 • Rendering and Presentation 836 20. Click the Duplicate button, as shown at the bottom left in Figure 19.13. 21. Call the new scene Syracuse at dusk (you can replace “Syracuse” with your location), then click OK. 22. Set the time for 7:30 PM (see Figure 19.13). 23. Click OK; your scene should look like Figure 19.14. 24. Click the Show Rendering Dialog button on the View Control bar. FIGURE 19.13 Changing the scene to dusk FIGURE 19.14 The rendering at night Interior Rendering 837 25. Set the Setting value to High. 26. Set Lighting Scheme to Exterior: Sun And Artificial. 27. Click the Artificial Lights button to make sure all your groups are present, and then click OK. 28. Click the Render button. Your scene should look like Figure 19.15. FIGURE 19.15 The rendering in daylight If you are actually in Syracuse during the winter, it would probably be a good idea to get inside! While we are in there, we can bring the experience that we just gained inside with us to create an interior rendering scene. Interior Rendering We create an interior rendering in almost exactly the same as an exterior render- ing. Of course, we will definitely use artificial lighting. We will also use sunlight, just to make sure we account for any natural light that comes into the building. The objective of this procedure is to create an interior lighting scene using a premade 3D perspective of a hallway: 1. In the Project Browser, find the 3D view called East Wing Corridor Perspective. 2. On the View Control bar, click the Show Rendering Dialog button. Chapter 19 • Rendering and Presentation 838 3. Set the Quality setting to High. 4. Set Resolution to Printer and to 300 dpi. 5. Set Lighting Scheme to Interior: Sun And Artificial. 6. Set Sun to Sunlight From Top Right. 7. Make sure Background Style is set to Color. 8. Click the Render button. Your hallway should resemble Figure 19.16. FIGURE 19.16 The interior corridor This is getting almost too easy! I suppose we could keep rendering all week, but in the interest of saving some trees, I encourage you to render just a little more. If you run into any trouble during your foray into additional rendering, give me a shout at ewing@cscos.com and ask your question. The winding stairs heading up to the balcony in the west wing would make a nice scene to hang on your cubicle or office wall! If you feel as though you have enough experience with rendering, let’s jump to the next section and tackle creating a nice walkthrough for a presentation. Creating Walkthroughs For some reason, you can show a client a beautiful rendering of a space or building you plan to design for them and still meet with a blasé, half-hearted reaction. Now, if you show them the same space, but as though you are walking through it … well then! The client perks right up. Creating Walkthroughs 839 Although this part of the chapter is not crucial to your expertise in Revit, it is certainly worth a glance. Sometimes it is the special tools that you can pull out of your belt that can win a job or impress your friends on a Saturday night. A walkthrough is a series of points you pick in a sequence in a plan view. It’s sort of like connecting the dots, but these dots will advance a frame as if you were walk- ing to the points you picked. The objective of this procedure is to create a walkthrough of the building and to export the walkthrough to an AVI file: 1. Go to the Level 1 floor plan. 2. On the View tab of the Ribbon, choose 3D ➢ Walkthrough, as shown in Figure 19.17. FIGURE 19.17 Finding the Walkthrough command 3. Zoom in on the east entry. 4. Start picking points, as shown by the numbers in Figure 19.18. 5. Keep picking points down the hallway, into the corridor, and into the west wing, as shown in Figure 19.19. 6. On the Modify | Walkthrough tab of the Ribbon, click Finish Walkthrough. 7. On the Modify | Cameras tab of the Ribbon, click the Edit Walkthrough button. Chapter 19 • Rendering and Presentation 840 FIGURE 19.18 Picking the points in the sequence FIGURE 19.19 Sketching the walkthrough path  Note that you can adjust the camera height on the Options bar. This is especially useful for walking up and down stairs. Creating Walkthroughs 841 8. In the Project Browser, find the Walkthroughs category and open the Walkthrough 1 view. 9. On the Options bar, change the first frame to 1, as shown in Figure 19.20. 10. In the View Control bar, click Realistic. 11. Select the crop region. 12. On the Modify | Cameras tab, select the Edit Walkthrough button (again). 13. On the Modify | Cameras tab, click the Play button, as shown in Figure 19.20. FIGURE 19.20 Clicking the Play button to start the walkthrough 14. When the walkthrough is done, you can click the button that con- tains the value of 300 (this is the number of frames) on the Options bar, as shown in Figure 19.21. 15. In the Walkthrough Frames dialog, change the Frames Per Second value to 20. 16. Run the Walkthrough again. This time it is sped up. Chapter 19 • Rendering and Presentation 842 FIGURE 19.21 Changing the frames The walkthrough is complete. One thing you certainly will be asked is if you can “give” the walkthrough to someone for a presentation. Luckily the answer is yes, and the person presenting does not have to be Revit literate, or even own the application. Exporting an Animation Exporting an animation is a great, but slightly hidden, feature. The Export function is not located on the Ribbon—you will find it in the Application menu, as shown in Figure 19.22. By exporting a walkthrough, you are creating an animated vector image (AVI) that will translate the native Revit walkthrough. It is quick and almost completely painless! To create an AVI of the walkthrough, follow these steps: 1. Click the Application button. 2. Choose Export ➢ Images And Animations ➢ Walkthrough, as shown in Figure 19.22. Creating Walkthroughs 843 3. Select the defaults in the next dialog, then click OK. 4. Find a location for the file and click Save. 5. Click OK in the Video Compression dialog. (You will have to sit and wait for Revit to go through the walkthrough as it creates the AVI.) FIGURE 19.22 Choosing to export the walkthrough 6. Find the AVI and run it to make sure it works. NOTE Just in case you are wondering, yes, the size of this AVI is over a gig. If necessary, you can attempt to compress the file as you export it, but the quality will probably degrade. Besides, memory is cheap these days. With the walkthrough complete, there is one more animation that we need to look at. It’s not as cool as the walkthrough, but it is just as interesting. This ani- mation is called a solar study. . the corridor at each cor- ner, and at the ends of the walls. 17. Create a new lighting group called Corridor Interior, and add the cor- ridor lights to the group. You now have three lighting. blasé, half-hearted reaction.
