Using Advanced 3D Features
AutoCAD for Mac's extended set of tools, menu options, and commands for working with 3D
drawings let you create 3D objects with few limitations on shape and orientation. This chapter
focuses on the use of these features, which help you easily generate 3D forms and view them in
both perspective and orthogonal modes.
In this chapter, you'll learn to do the following:
Master the User Coordinate System
•u
•u
Understand the UCS options
Use viewports to aid in 3D drawing
•u
Create complex 3D surfaces
•u
Create spiral forms
•u
•u
Create surface models
Move objects in 3D space
•u
Setting Up AutoCAD for This Chapter
Before you start, I'd like you to set up AutoCAD in a way that will make your work a little easier.
You'll use the Modeling Tool Sets panel you were introduced to in Chapter 19, “Creating 3D
Drawings.” To do so, follow these steps:
1.
Start AutoCAD.
2.
Click the Tool Sets icon at the top of the Tool Sets palette.
3.
Make sure Modeling is selected. You'll see the modeling tools appear.
In Chapter 19, you started a new 3D model using a template set up for 3D modeling. Here
you'll start to work with the default 2D drawing. Now you're ready to get to work.
