1. Learning Objectives Create a rendered scene. Set natural and artificial lightings. Use different materials and textures. Create and render a walkthrough. Add people and vehicles to a building model. Use the Decal tool.

2.  RENDERING IN REVIT ARCHITECTURE Art and a process of generating digital image from a three-dimensional model containing geometry, texture, light, and shading information through a computer program Helps you give a clear picture of the final outcome of an architectural project Bridges the gap between the final outcome and the two-dimensional working drawing

3. Rendering Workflow Figure 1 The rendering workflow chart

4. Seven steps in the process of rendering in Autodesk Revit Architecture 2012. Step 1 - Creating a Three-Dimensional View Step 2 - Specifying Render Appearances and Applying Materials Step 3 - Applying Lights Step 4 - Using Entourages and Decals Step 5 - Defi ning Render Settings Step 6 - Creating the Rendered Image Step 7 - Exporting the Rendered Image

24.  Tutorial 1 Using the project file, c14_Apartment1_tut1.rvt, created in Tutorial 1 of Chapter 14, render the interior view of the living room, as shown in Figure 20, for the first floor. Replace the existing finish of materials assigned to the floor, wall, ceiling, and chair with the following new materials/textures (given with their path). Also, create a 200-frame interior walkthrough at eye level using the path, as shown in Figure 21. Figure 21 Rendering the interior view of the living room

26. The rendered image can be downloaded from: http://www.cadcim.com/Revit_2010/Revit_2010.htm Add lights based on the parameters given below and also as shown in Figure 23 and 24. Figure 23 Sketch floor plan for adding table lamps to the living room Figure 24 Sketch ceiling plan for adding ceiling lights to the living room

27. The following steps are required to complete this tutorial: 1.Open the specified project file and the first floor plan view. 2.Use the Paint tool to apply materials to the floor. 3.Use the Materials dialog box to change the finish of the ceiling, walls, and textile of the chair, refer to Figures 25 and 26.

36.  Tutorial 2 Render the exterior view of the Office Building 2 project using the file created in Exercise 3 of Chapter 14. Replace the existing finishes of materials assigned to the exterior walls with the following new materials/textures, add trees, and add entourages to the project based on the first floor plan view, as shown in Figure 36. Render the 3D view 1 based on the rendered view shown in Figure 38. Figure 37 Sketch plan for adding toposurface, trees, and entourages to the Office Building 2

37. Figure 38 Rendered exterior view for Office Building 2 project

38. The following steps are required to complete this tutorial: 1.Open the specified project file and the first floor plan view. 2.Use the Paint tool to apply materials to the exterior walls. 3.Add a toposurface to the building model and assign material to it. 4.Add trees to the exterior view. 5.Add entourages to the building model. 6.Set up the rendering scene and render.
