Rendering 3D Drawings
In this chapter, you'll learn how to use rendering tools in AutoCAD to produce rendered still
images of your 3D models. With these tools, you can add materials and control lighting. You
also have control over the reflectance and transparency of objects.
In this chapter, you'll learn to do the following:
Simulate the sun
•u
•u
Create effects using materials and lights
Control your render quality
•u
Print your renderings
•u
Testing the Waters
Before we get into the main tutorial in this chapter, let's first take a peek at what's possible with
AutoCAD's rendering tools. This first exercise will give you a chance to learn how you can
quickly see a rendered view of a 3D model and how you can easily add materials to objects.
The first file you'll work with in this section is simply a collection of primitive shapes in
a random arrangement. First, you'll use the Render command to view the file without any
materials, and then you'll add a few materials to get familiar with the Material Browser and
see how it can be used to create a more lifelike rendering. Start by opening a sample file and
render it as is:
1. First, turn on the Selection Cycling system variable by entering SELECTIONCYCLING
2 ↵. You'll need it in some of the later exercises.
2. Make sure Modeling is selected in the Tool Sets palette.
3. Next, open the Material Browser by choosing View Render Materials Browser
(Figure 21.1).
4. Open the Rendering_example_raw.dwg file.
5. Click the Render tool in the lower part of the Tool Sets palette (Figure 21.2).
6. The Render window opens and takes a moment to produce the rendered view
(Figure 21.3).
