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
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.
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.
