An Overview of Pro/ENGINEER

Pro/ENGINEER is a computer graphics system for modeling various mechanical designs and for performing related design and manufacturing operations.

The system is a feature-based, parametric solid modeling system with many design and manufacturing applications.

Feature-Based Design Create sketched features including protrusions, cuts, and slots

made by either extruding, revolving, or sweeping along a 2D sketched trajectory, or blending between parallel sections

Create pick and place features, such as holes, shafts, chamfers, rounds, shells, flanges, ribs, etc.

Reference datum planes, axes, points, curves, coordinate system, etc.

EXTRUDE

Two dimensional closed objects can be extruded to give solid objects

The direction of the extrusion is typically normal to the 2-D cross sectional sketch

The height of extrusion can be specified

SWEEP

The path of the extrusion must be defined (trajectory)

The extruded cross section must be defined

The cross section stays normal to the path

REVOLVE

Two dimensional closed objects can be revolved to give solid objects

The axis of rotation must be defined

The angle of revolution must be specified

BLEND

Smooth transition can be made between two closed shapes with similar geometry (i.e. equal number of vertices)

The distance between sections must be defined

The angle of twist between sections must be specified

Manipulating Geometry and Parametric Modeling

Basic Modes

Sketcher: Define the 2D cross-section (or section) of an object model for sweeping.

Part: Create the solid model of a part. Assembly: Form the solid model of an

assembly of multiple components. Drawing: Produce engineering drawings

of parts and assemblies created in Pro/E.

Pro/E Modeling Procedure

User Interface

The window on the left is the navigator window. The large window in the middle is web browser

window. The pull-down menu is on the top. Below the pull-down menu, there is a series of

shortcut buttons/keys. Below the pull-down menu, there is a command or

message window. There are some sketch toolbar on the right hand side. On line help is available when click on “?” button.

Set Working Directory

Set temporary working directory: File -> Set Working Directory, select working directory.

Set permanent working directory:Click on the shortcut icon of Pro/E -> Properties, set the Start in field to the directory that you want Pro/E to start up in the Properties dialog box.

The temporary working directory needs to be set again whenever you start Pro/E while the permanent one dose not.

Display a Model

Set working directory. File -> Open, select a *.prt file. Spin the object by pressing and holding

down the middle mouse button. Spin center on: object spins about the spin

center. Spin center off: object spins about the position of the cursor.

Zoom in/out by simultaneously holding down Ctrl and middle mouse button, or using zoom in/out button.

Move the object by simultaneously holding down shift and middle mouse button.

Display a Model

Turn View/Orient mode on -> right mouse button -> velocity: the object spins as long as the middle mouse button is pressed down.

Click on the saved view list icon: shows the engineering drawings.

Display modes: Wireframe, Hidden Line, No Hidden, and Shading icons.

Tools -> Model Player: to see the step forward through the model one feature at-a-time.

Remove Current Model

File -> Erase -> Current: remove current model for pro/E.

Exercise Set temporary & permanent working directories. Download example .prt files from following URL:

http://www.msi.umn.edu/~chenxy/bme506link.html

Open one of downloaded files. Move, spin, and zoom in & out the object. Change the display mode to see the difference. Check your working directory after you save or

delete file/files.
