Architectural In this problem, you will attach materials to the objects in an existing drawing and render the scene. A. Open drawing P16-2 from Chapter 16. Save the drawing as P17-2. B. Attach the materials of your choice to the objects in the scene. Do not be restricted by the names of the materials. For example, a concrete material may be suitable for items such as foliage or even carpet with a simple color change. Be creative. C. If the items in the scene were downloaded from the Internet, they may be blocks with nested layers. Instead of exploding the blocks, use the MATERIALATTACH command and attach materials to the layers on which the nested objects reside. D. Turn on the sun and adjust the time to create good shadows. Refer to Chapter 16 for an introduction to sun settings. E. Render the scene. Save the rendering as P17-2.jpg. Save the drawing.
