Wiley Mastering Autodesk Inventor and Autodesk Inventor LT 2011 978-0-470-88287-0 ユーザーズマニュアル

In this chapter, you will be introduced to the concept of parametric 3D design and the general 
tools and interface of Inventor. This chapter will focus on the concepts of parametric modeling 
and the work flow, tools and interface elements found in Inventor that are used to turn your ideas 
into a design.

In this chapter, you will learn how to:

Create parametric designs

•u

Get the “feel” of Inventor

•u

Use the Inventor graphical interface

•u

Work with Inventor File Types

•u

Move from AutoCAD to Inventor

•u

Create 3D virtual prototypes

•u

Use functional design

•u

Autodesk Inventor is first and foremost 3D parametric modeling software. And although it has 
capabilities reaching far beyond the task of creating 3D models, it is important for you to under-
stand the fundamentals of parametric 3D design. The term parametric refers to the use of design 
parameters to construct and control the 3D model you create. 

Most typically, the 3D model starts with a 2D sketch, which is assigned dimensions and 2D sketch 
constraints

 to control the general size and shape. These dimensions and constraining geometries 

are the parameters, or input points, that you would then change to update or edit the sketch. For 
instance, Figure 1.1 shows a base sketch of a part being designed.
