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.
