The Advanced AutoCAD 2018: A Problem Solving Approach, 3D and Advanced textbook contains detailed explanation of AutoCAD commands and their applications to solve design problems. Every AutoCAD command is thoroughly explained with the help of examples and illustrations. This makes it easy for the users to understand the functions and applications of the tools and commands. After reading this textbook, you will be able to create 3D objects, apply materials to objects, generate drafting views of a model, create surface or mesh objects, and render and animate designs, and understand 3D Printing.The book covers designing concepts in detail as well as provides elaborative description of technical drawing in AutoCAD including orthographic projections, dimensioning principles, sectioning, auxiliary views, and assembly drawings. While going through this textbook, you will discover some new unique applications of AutoCAD that will have a significant effect on your drawings and designs. The textbook also covers the 3D printing tools introduced in AutoCAD. Some of the Salient Features of this textbook are as follows:

• Comprehensive textbook consisting 14 chapters that are organized in a pedagogical sequence.

Understanding the Concept of Rendering

A rendered image makes it easier to visualize the shape and size of a 3D object as compared to a wireframe image or a shaded image. A rendered object also makes it easier to express your design ideas to other people. For example, to make a presentation of your project or design, you do not need to build a prototype. You can use a rendered image to explain your design more clearly because you have a complete control over the shape, size, color, surface material, and lighting of the rendered image.

Additionally, any required changes can be incorporated into the object, and it can be rendered to check or demonstrate the effect of these changes. Thus, rendering is a very effective tool for communicating ideas and demonstrating the shape of an object.

Generally, the process of adding a realistic effect to models (rendering) can be divided into the following four steps:

1. Selecting the material to be assigned to the design.

2. Assigning materials and textures to the design.

3. Applying additional effects to the model by assigning lights at different locations.

4. Using the Render tool to render the objects.

Assigning Materials

After creating a model, you need to assign various types of materials to the objects in it to give it a realistic appearance. These materials create three types of effects. These effects are discussed next.

In the first type of material effect, the object is rendered without actually displaying the effect of the material applied. A global material is assigned to all objects. On rendering,...
