Course Overview
Course Overview
Course Description
Industrial Design with Shape Studio is a method based course that addresses
the Unigraphics functionality used to define complex styling shapes using curves
and surfaces. Generating creative designs consists of creating developed curves,
complex surfaces with tangent/curvature continuity, blends, and transition
surfaces. This course also introduces dynamic analysis and edit methods and
advanced visualization techniques.
Intended Audience
This course is intended for Industrial Designers/Stylists and Lofters who have a
need to create complex styling shapes using curves and surfaces.
Prerequisites
No prerequisite is required; however, a basic understanding of three
dimensional modeling and/or working knowledge of the Unigraphics user
interface is helpful but not necessary.

Course Overview
Class Standards for Unigraphics Part Files
The following standards will be used in this class. Standardization allows users
to work with others parts while being able to predict the organization of the
part file. All work should be performed in accordance with these standards.
Class Part File Naming
This class utilizes the following filenaming standard:
user's initials
(3 characters)
part name
(1 - 22 characters)
***_xxxxxxxxxxxxxxxxxxxx•prt
extension
(4 characters)
underscore delimiter
When the student is requested to save a part file for later use, the initials of the
student's given name, middle name, and surname replace the course identifier ***" in
the new filename with the remainder of the filename matching the original. These files
should reside in the student's personal directory.
TIP Currently up to 128 characters are valid for file names. A four
character extension (.prt, for example) is automatically added to define
the file type. This means the maximum number of user defined
characters for the file name is actually 124.
Layers and Categories
The student will notice that there are 256 layers available and they may be
utilized and organized any way the user sees fit.

however, you may reset the default colors in any part file at any time.

Seed Part
Seed parts are an effective tool for establishing customer defaults or any
settings that are partĆdependent (saved with the part file). This may include
nonĆgeometric data such as:
D
Layer categories
D
UserĆdefined views and layouts
D
Part attributes
TIP Once a seed part is established, it should be writeĆprotected to avoid
accidental modification of the seed part.
Two seed part files are available for use in this course. These files incorporate
the standards described above, and include the TFRĆTRI view as the default.

How to Use This Manual
It is important that you use the Student Guide in the sequence presented
because later lessons assume you have learned concepts and techniques taught
in an earlier lesson. If necessary, you can always refer to any previous activity
where a method or technique was originally taught.
The format of the activities is consistent throughout this manual. Steps are
labeled and specify what will be accomplished at any given point in the activity.
Below each step are action boxes which emphasize the individual actions that
must be taken to accomplish the step. As your knowledge of Unigraphics
increases, the action boxes may seem redundant as the step text becomes all
that is needed to accomplish a given task.

summary
One or more included
in most lessons
While working through lesson activities, you will experience a higher degree of
comprehension if you read the CUE and Status lines .
It is recommended that students who prefer more detail from an Instructor Led
Course ask questions, confirm with restatement, and, more importantly, attend
and pay attention to the instruction as it is given.
Obviously, it is always necessary for students to consider the classroom situation
and be considerate of other students who may have greater or lesser needs for
instruction. Instructors cannot possibly meet the exact needs of every student.
At the start of each class day you will be expected to log onto your terminal and
start Unigraphics, being ready to follow the instructor's curriculum. At the end
of the day's class you should always quit Unigraphics and log off the terminal.

Course Overview
Workbook Overview
The workbook is designed to lead the student through the aesthetic design of a
snowmobile hood and windscreen using many functionalities of Unigraphics.
During this activity, the student will use the artist's conceptual sketches to
create, edit and analyze splines and sheet solids, apply materials and textures
to the completed model, add light sources and a background image and render
the final product image.
This project is intended to give the student a strong foundation in the
Unigraphics skills required to design studio-quality free form surfaces and
showcase the completed models using visualization techniques.
It is the intent of this activity to allow the student to apply the skills taught in
this course; however, the time constraint of this course is also a factor. At any
point when progress is not being made, enlist the help of your instructor.

Starting Unigraphics
The first step in working in Unigraphics is to log on to a workstation and start a
Unigraphics process. Because this procedure varies from company to company,
consult the system administrator for a site specific procedure to follow.
Unigraphics Windows - No Part
The graphic below shows the No Part" Unigraphics interface. This interface
only allows the user to adjust default options, open an existing part or create a
new part in which to work.

The Gateway Application
The Gateway application is entered upon retrieval of an existing part or
creation of a new part in Unigraphics. Gateway allows for review of existing
part files and the ability to obtain information on those files. To create or edit
objects within a file, one of the other applications such as Modeling or Shape
Studio must be entered.

Cue/Status line
The Cue/Status line appears at the bottom of the main application window. The
purpose of the Cue line is to prompt for user interaction. The purpose of the
Status line is to give the user visual feedback regarding system activity.
NOTE: In a Windows environment the Cue line may be relocated to the
top of the user interface. To do this click the third mouse button (MB3)
in the toolbar area (see Toolbars section of this lesson) and choose
Customize at the bottom of the dialog.
Choose the Options tab; then choose
Top in the Cue/Status Position box.
The change will take effect when the
next session of Unigraphics is
launched.
