Introduction
CATIA Version 5 Part Design and Sketcher
Upon completion of this course the student should have a full understanding of the
following topics:
- Creating sketches
- Constraining sketches
- Modifying sketches
- Creating parts
- Modifying parts
- Performing boolean operations on parts
- Basic use of surfaces in part design
- Applying materials to parts

Manual Format
It is important to understand the format of the manual in order to use it most effectively.
This manual is designed to be used along with an instructor; however, you will need to do a
lot of reading as well, in order to fully understand CATIA Version 5. The exercises in this
book will list steps for you to complete, along with explanations that try to inform you what
you have just done and what you are getting ready to do. The actual steps are in bold type
and the information that follows the steps is for your benefit. Anything that appears in
italics refers to a message CATIA providesthis includes information in pull-down menus,
pop-up windows and other messages. Bold type is also used to call your attention to key
terms you may not yet be familiar with.
An example of a step and its explanation is shown below (note: normally the lines will not
be there):
Select a location to the right of the origin. This specifies the other end point of the line.
You will continue specifying locations in order to complete your profile. It should appear
similar to the diagram shown below.
As you can see, the desired action blends in with the text except that it appears in bold.
The information following the step explains what that step accomplished and where you are
going next. It is important for you to read this information to help in your understanding of
CATIA Version 5.
Also, you will find that the exercises build upon themselves. Later exercises often assume
you know how to do certain steps which have been covered in earlier exercises. If you did
not quite pick up what you needed to know from an exercise, you will probably wish to
review it several times before moving on to the more advanced sections. As you progress
through the manual, it expects that you are learning and therefore you are able to do a lot
more with fewer steps. Eventually, you are expected to be able to create parts without any
steps.

Part Design & Sketcher
CATIA Version 5 uses the Sketcher as its principal method to create profiles. These
profiles can be constrained using many different types of constraints. The first objective of
the course is to learn to use the Sketcher and constrain your profiles to the desired
specifications. If you have used the Dynamic Sketcher from CATIA Version 4, this will
look very similar. Otherwise it is a new environment and it can be frustrating at first,
especially if you already know CATIA Version 4. However, in time you will find that it is a
very powerful method for creating profiles, and is easy to use.
The second objective of the course is to use these sketches in part design. The sketches are
used to define the two-dimensional cross-sections to be used to design three-dimensional
shapes. There are a few different shapes that can be made as well as various operations that
can be performed on them. By combining these shapes and operations, you can design a
variety of parts.
The third objective of the course is to familiarize you with the advanced methods of creating
sketches and parts. This includes using construction geometry and projecting threedimensional
geometry to the sketch plane. This will include the use of formulas to set up
typical values at multiple locations as well as more complex formulas to provide a more
dynamic sketch. In terms of part design, you will learn how to use multiple parts and
perform boolean operations on them.
The fourth objective is to become efficient at modifying your designs. You can modify your
design either by changing the parameters of a part operation or by modifying the sketch that
was used. In CATIA Version 5 this is fairly simple, and the modification of your design is
the real strength of part design.
The fifth objective is to introduce the use of wireframe and surfaces in the part design
process as well as applying various materials to your design. This is meant only to be an
introduction and not a complete course on these subjects.
In conclusion: You should be able to design many parts using the Sketcher and the Part
Design workbenches of CATIA in an efficient manner. As mentioned before, you may find
it frustrating at first but very natural by the end of the course.
