Creo Parametric Modeling with Augmented Reality

CHAPTER 1Introduction to Parametric Design

1.1 Introduction

Computer‐aided design (CAD) is the development of new part models and modification of already existing parts’ designs for new prototypes of complex assemblies such as cars, planes, computers, etc. The development and modification of parts include analysis of design data from customers and other stakeholders. Additionally, the CAD provides communication tools such as drawings and simulations to accurately estimate and manufacture customer’s specifications.

This chapter introduces the basic concepts behind parametric design and feature‐based modeling. Parametric design is a process used to manipulate, regenerate, and design objects based on a set of rules or parameters. There are many concepts that appear regularly in parametric design projects. One important concept is repetition, which works best when it is used in parallel with rotation, scaling, and movement. This simply means to copy an object multiple times while introducing a gradual change in its scale for example. Within this chapter, engineering graphics and three‐dimensional modeling concepts will be explored. Additionally, parametric modeling principles will be covered. Upon finishing this chapter, you will be able to:

• Describe the utilization of computer‐aided design within engineering graphics.
• Compare three‐dimensional modeling techniques.
• Describe concepts associated with parametric modeling and design.
• Describe the use of parametric design within a ...
