Preparations

Objectives:

In this chapter you

will

ieam:

• The level of expertise required for 20 CAD design in eng ineering

• How

to

ut ilize sketch tools, mirror, draft for part modeli ng

• How to model 3D parts using Extrusion. Revolved. features tools

as

well as

using Reference Planes

• How

to

solve part modeli ng problems required for Certified SolidWorks

Associate CSWA

INTRO

UC

TION

This goal

of

th is chapter

is to

assist readers to achieve the level of expertise in 20 CAD

design as

it

applies to engineer

in

g and to hel p them pass the Certified SolidWorks

Associate (CSWA) which is synonymous with competence

in

olidWorks

at

foundation

and apprentice level of 20 CAD design and engineering practices and principles. A

number of tutorials are presented in this chapter to

ac

hieve thi s goal.

This chapter discusses part modeling

at

the level

of

CSWA and most

of

the examples are

similar to the materials covered in the CSWA examinations. Students preparing for th is

exam will find this chapter

he

lpful. Instructors should consider covering this chapter

before movi ng to the next chapter which pitches at a higher level.

Exercises

I Referring to the part in Tutorial 4-2 (see Figure PI , create a mirror

of

the part about

the right vertic

al

face. Apply the same material and compute the material properties

of

the part.

Figure PI

2.

Referring to the part in Tutorial 4-3A (see Figure 1 2), change the angle

of

the

ve

rtical

feature from 30-deg to 90-deg. App

ly

the same material and compute the material

properties

of

the part.

3. Referring to the part in Tutorial 4-

5A

(see Figure P3), create a mirror

of

the part about

the right vertical face. Apply the same material and compute the material properties

of

the part.
