Chapter 1
Inventor Design Philosophy
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.

Understanding Parametric Design
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.

Creating a Base Sketch
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.
