• Describe how to use Pro/ENGINEER as a solid modeling designtool
• Describe the three main Pro/ENGINEER design concepts
nova - HGP
Trang 24Pa g e 1 - 2 I n t r o d u c t i o n t o P ro / EN G I N E E R
NOTES
PRO/ENGINEER CORE CONCEPTS
You use Pro/ENGINEER to create solid models of your designs The
three-dimensional work environment enables you to take advantage of:
• Feature-based modeling
• Associativity
• Parametric relationships
Solid modeling has many advantages over two-dimensional design:
• Solid models have volumes and surface areas
• You can calculate mass properties directly from the geometry youcreate
• When you manipulate a solid model, the model itself remains a solid
Figure 1: Different Views of a Solid Model
nova - HGP
Trang 25I n t r o d u c t i o n t o P ro / EN G I N E E R Pa g e 1 - 3
NOTES
Designing Feature-based Models
The models you create in Pro/ENGINEER are feature-based This meansthat the geometry of your part model is composed of one or more features
A feature is the smallest building block in a part model
Pro/ENGINEER enables you to build a model incrementally by addingindividual features one at a time As you construct your model, you chooseyour building blocks, as well as the order that you create them
Creating models in Pro/ENGINEER involves incorporating your “designintent” into the model Design intent is the reason for adding every feature.For example, you add hole features to a model because the resulting partmust be assembled to another part, and the holes are needed for thescrews The next figure shows how a typical part can be designed byadding one feature after another to a base model
Base Feature Protrusion Added Blind Cut Added Chamfers Added
Thru-All Cuts and Holes Added Chamfer Added Rounds Added
Figure 2: Building Models Feature by Feature

Trang 26Pa g e 1 - 4 I n t r o d u c t i o n t o P ro / EN G I N E E R
NOTES
Designing with Parametric Features
The designs you create in Pro/ENGINEER can be parametric This means
that their dimensions are controlled by parameters, which are relateddimensions
Parametric modeling has many advantages:
• Model geometry can be changed by modifying dimensions
• Designated features can be related to each other
• Modifications to certain features propagate changes to other features
• Parent/child relationships can be developed between features.

Trang 27I n t r o d u c t i o n t o P ro / EN G I N E E R Pa g e 1 - 5
NOTES
Taking Advantage of Associativity
Pro/ENGINEER models usually consist of several parts, assemblies, and
drawings All of these objects are fully associative in Pro/ENGINEER.
This means that changes made at one level will propagate to all the levels.For example, if you change dimensions on a drawing, the change will bereflected in the associated part The following figure shows associativitybetween a part and an assembly

THE PRO/ENGINEER INTERFACE
Figure 1 Sample Model Display in Main WindowWhen you start Pro/ENGINEER, the main window opens on your desktop.You create your designs in this window This window has four main parts:
• Pull-down menu
• Toolbar
• Display area
• Message area
Accessing Commands with Pull-Down Menus
You can always use the following Pro/ENGINEER pull-down menus:
• File – File manipulation commands
• Edit – Object manipulation and action commands
• View – Model display commands
• Datum – Datum feature commands
nova - HGP
Trang 31T h e P ro / E N G I N E E R I n t e rf a c e Pa g e 2 - 3
NOTES
• Analysis – Model, surface, curve, motion, and sensitivity andoptimization commands
• Info – Query and report commands
• Applications – Launch commands for other Pro/ENGINEER modules
• Utilities – Working environment customization commands
• Windows – Window manipulation commands
• Help – Help commands
Accessing Frequently-used Commands with the Toolbar
The Pro/ENGINEER toolbar contains icons for frequently usedcommands Toolbar buttons are provided as an alternative to menucommands You can customize you toolbar
Figure 2: Pro/ENGINEER Toolbar
Manipulating Your Designs in the Display Area
Pro/ENGINEER displays parts, assemblies, drawings, and models on thescreen in the display area An object’s display depends on the currentenvironment settings When you select the model on the screen, thesystem distinguishes between an edge and a surface of the model byhighlighting them in two different colors
Note:
Surfaces of models are valid in Pro/ENGINEER regardless of the model display.

Trang 32Pa g e 2 - 4 I n t r o d u c t i o n t o P ro / EN G I N E E R
NOTES
Viewing Information in the Message Area
The message area:
• Displays status information for every operation performed
• Displays queries and hints to simplify the task you are working on
• Prompts you for additional information (the text message isaccompanied by an optional audible signal)
• Displays icons that represent different kinds of information, such aswarnings or status prompts
To view old messages, you can use the scrollbar located on the right
Every type of Pro/ENGINEER object has a different file extension
Typical file extensions are described next
• PRT – Part files allow you to create 3-D models consisting of manyfeatures
• ASM – Assembly files contain information on how 3-D parts andassemblies are assembled together
• DRW – Drawing files contain 2-D fully dimensioned drawings of parts
or assemblies
• SEC – Sketch files contain 2-D non-associative sketches that can beimported while in sketcher mode. There is also a SKETCHER modethat allows you to create two-dimensional sketches that are parametric

NOTES
Working with Dialog Boxes
Dialog boxes in Pro/ENGINEER are used for model manipulation, featurecreation, and saving There are two kinds of dialog boxes: generalandmodel.
The General Dialog Box
A general dialog box performs general functions such as saving, viewing, and interrogating The following figure represents some of the common elements in a regular dialog box.
Trang 34Pa g e 2 - 6 I n t r o d u c t i o n t o P ro / EN G I N E E R
NOTES
The Model Dialog Box
A model dialog box creates and modifies model geometry by prompting
you for required and optional elements from the user.
Required elements are modifiable properties of a Pro/ENGINEER featurethat must be specified to completely define a feature Optional elementsare additional operations that you may perform; but they are not necessaryfor completing the feature
The following figure illustrates a model dialog box that defines a ROUNDfeature
Figure 4: A Model Dialog BoxThe option buttons in a model dialog box are:
• Define – Defines and/or changes selected elements in the dialog box
• Refs – Displays the external references of the current selectedelement
• Info – Generates a listing of the properties of the feature that you arecreating
• OK – Completes the definition of the elements, creating the feature ormodel entity
• Cancel – Cancels the current feature or model entity
• Preview – Checks geometry before completing the feature definition
nova - HGP
Trang 35Using the Model Tree
The MODEL TREE presents the model structure feature by feature Youcan select features from the MODEL TREE for modification and deletion.MODEL TREE icons indicate the corresponding item type and its currentstatus

NOTES
Using the Menu Manager
The MENU MANAGER displays a list of menus that you can use to create,modify, and duplicate model geometry
Using the MENU MANAGER, you drive along a certain path to complete atask by making choices from menus Each time you choose an option from
a submenu, Pro/ENGINEER opens another submenu until you havefinished making selections
Obtaining Additional Information with Help
When you hold your mouse over any menu option, an on-line helpmessage displays on the bottom of the current active window If you needadditional help, you can right-click the menu option and select Get Help
from the pop-up menu
Note:
The system administrator must install and setup the online documentation for you to be able to access this functionality.
Working with Multiple Models
You can have multiple models in session at one time—each windowcontaining a model—making it possible to refer to one model whileworking on another However, Pro/ENGINEER only allows you to work
