How to Use This Manual
It is important that you use the Student Manual 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 will seem redundant as the step text becomes all that
is needed to accomplish a given task.
Step 1 Open part file pau_topic_1.
- From the menu bar, select File
- Choose Open.
- Double-click on the parts sub-directory.
- Select the file pau_topic_1 and choose OK.

Class Standards
The following standards will be used in this class. Standardization allows users
to work with and predict the organization of parts created by others . All work
should be performed in accordance with these standards.
About Part File Naming
In order to facilitate the identification of design models without requiring the
user to open a part file, the user community must establish standard names for
the various files associated with the part definition. The following is a sample
usage of a filenaming standard:
x x x _ x x x x x x x x x x x x _ x x x x _ x x x x
•
p r t
identifier
(3 characters)
part name
(25 characters)
configuration
(4 characters)

revision
(4 characters)
extension
(4 characters)
TIP
Currently up to 128 characters are valid for file names. A four
character extension (.prt) is automatically added to define the file
type. This means the maximum number of user defined characters for
the file name is actually 124.

Class Part File Naming
This course utilizes the following filenaming standard:
pau_ x x x x x x x x x x x x x x x x x x x x _ x
•
p r t
course identifier
(3 characters)
part name
underscore delimiter
unique identifier number
extension
(4 characters)
underscore
delimiter

Where 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 pau" in the new filename with the remainder of the filename
matching the original.
Expressions
The student will notice that there is a standard set of expressions resident in
each of the part files as follows:
Expression Name Intended Use
bend_r=.5 identifies bend radius for sheet metal parts
dia=.5 identifies diameter
h=1 identifies height
l=1 identifies length
out_r=.625 identifies the outside radius for sheet metal
parts
rad=.25 identifies Radius
thk=.06 identifies thickness
w=1 identifies width
These expressions could be entered by the user in each file or could be a
standard expression file that could be imported into the part file by the user.
Expression files that are valid for importing carry the file extension of .exp. The
total number of characters allowed in an expression is 132.

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 Preferences
D Commonly used expressions
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, pau_seedpart_in for inch
parts and pau_seedpart_mm for metric parts. These files incorporate the
standards described above, and include the TFRĆTRI view as the default view.

Definition of Terms
Explicit Modeling
Explicit modeling is modeling that is not parametric. Objects are created
relative to model space, not each other. Changes to one or more objects do not
necessarily affect other objects or the finished model. Examples of explicit
modeling include creating a line between two existing points, or creating an arc
through three existing points. If one of the existing points were moved, the
line/arc would not change.
Parametric Modeling
A parametric model is one in which the values (parameters) used for the
definition of the model are stored with the model for future editing. Parameters
may reference each other to establish relationships between the various
features of the model. Examples include the diameter and depth of a hole, or
the length, width, and height of a rectangular pad. The designer's intent may be
that the hole is always as deep as the pad is high. Linking these parameters
together may achieve the desired results. This is not easily accomplished with
an explicit model.
ConstraintĆbased Modeling
A constraint-based model is one in which the geometry of the model is driven,
or solved, from a set of design rules applied to the geometry defining the model
as constraints. These constraints might be dimensional constraints (such as
sketch dimensions or positioning dimensions) or geometric constraints (such as
parallelism or tangency). Examples include a line tangent to an arc, where the
designer intends for that tangent condition to be maintained even though the
angle of the line may change, or a perpendicular condition being maintained as
angles are modified.

Hybrid Modeling
Hybrid modeling refers to the selectively combined use of the three types of
modeling described above. Hybrid modelers allow designers to use parametric
modeling where needed, without requiring that the entire model be constrained
before proceeding. Because of this, designers have more flexibility in modeling
techniques. The Unigraphics hybrid modeler supports traditional explicit
geometric modeling along with constraintĆbased sketching and parametric
feature modeling. All tools are integrated so they can be used in combination.

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,
and platform to platform, consult the system administrator for a site specific
procedure to follow. The Unigraphics NX Activity Menu shown below will not
be displayed on Windows workstations, and may or may not be displayed at
Unix workstations. It is shown here to describe the options available in case this
is the normal start dialog box at your site.
