MEMD261 Computer Aided Design
Pro Engineer Concepts, Interface, Part
Creation Basics, and Models in ProEngineer
Pro Engineer
More advance drafting software in the
market.
Powerful drafting tool in Eng.
Industry.
Is a solid modeler-has volume&surface
area.
Allows user to input mass properties as
part of model design.
Concepts
1)Featured-Based
ProE is a feature-based solid modeling
tool
It builds the model using individual
blocks one at a time.
Examples of features are Protrusion,
Cut, Hole, Chamfer, Round and etc.
2) Associative
ProE can be used to create isometric
drawings, orthographic drawings, and
assembly drawings.
If you change a part in an assembly,
the system automatically reflects that
change in any other parts and drawings
of that assembly.
3) Parametric
Features are interrelated, so
modifications of a single feature
propagate changes in other features as
well.
Relationships between features develop
when one feature references another,
known as a parent/child relationship.
Pro Engineer Interface
Accessing ProE
Double clicking the short cut icon
on the desktop.
The Main Window
When you start ProE, the Main window
composed of 5 areas opens on your
desktop.
ProE Interface
The pull-down menus on the menu bar at the top
of the window
Folder navigator: enables you to navigate folders
Web browser: to browse Web pages on Internet.
The toolbar below the pull-down menus contains
shortcut commands and the toolbar on the right
contains feature tools.
The display area displays the model graphic
The message area displays system messages that
prompt you for required information.
Working with models
In ProE you can work with parts,
drawings and assemblies.
System automatically recognizes type of
the model by the extension;




.prt signifies part models
.asm signifies assembly model
.drw signifies drawing models
.sec signifies section (2D sketch)
Part Design Basics
1) Select options(icons) that describe
the general feature you want to create.
2) Establish a sketching plane by
selecting datum planes from the default
datum planes system.
3) Sketch the basic shape (2D) of the
feature.
4) Add or modify dimensions to the
sketched shape.
5) Modify and redefine the created
feature.
Types of commonly used
sketched features
Extrude:Protrusion/Remove material
Revolve
Variable sweep
Chamfer
Round
Rib
Shell
Hole
Some Sketcher Commands
The basic sketcher tools/commands are
located on the toolbar menu on the
right of the screen once you start a
sketcher session
Pick items
Create lines
Create rectangles
Some Sketcher commands
Create circles
Create arcs
Create redefining dimensions
Modify dimensions
Impose sketcher constraints
Create text
Continue with the current session

Functions Of The Middle
Mouse Button In ProE
To SPIN-Middle mouse button:hold down and
drag to rotate a model in 3-D.
To PAN-SHIFT+Middle mouse button :hold
down and drag to to move the model across
the screen.
To ZOOM-CTRL+Middle mouse button: hold
down and drag vertically to zoom in/out.
To TURN- CTRL+Middle mouse button: hold
down and drag horizontally to turn the model
normal to the screen.
Models of Pro Engineer
Basically there are 3 types of
models:
1) Part model


.prt signifies a part model.
A part model allows you to create a 3D
model consisting of features.
Models of Pro Engineer
2) Drawing model


.drw signifies a drawing model.
A drawing model allows you to create a 2D,
fully dimensioned drawing of a part or
assembly.
Models of Pro Engineer
3) Assembly model


.asm signifies an assembly model.
An assembly model allows you to create a
3D model in which you can assembly parts
together.
