Learn ProE Step by Step In Simple Language From Basic to Professional training

1. What is Pro/ENGINEER?
Pro/Engineer feature-based, associative solid
modeling software. The application runs on
Microsoft Windows platform, and provides
solid modeling, assembly modelling and
drafting, finite element analysis, and NC and
tooling functionality for mechanical engineers.
The Pro/ENGINEER name was changed to
Creo Elements/Pro

2. What is CAD/CAM?
Computer-Aided Design
Computer-Aided Manufacturing
COMPUTER-AIDED DESIGN
Engineers use CAD to create two- and three-dimensional drawings, such as
those for automobile and airplane parts, floor plans, and maps. While it may
be faster for an engineer to create an initial drawing by hand, it is much more
efficient to change and distribute drawings by computer.
COMPUTER-AIDED MANUFACTURING
CAM uses a computer to control the manufacture of objects such as parts,
which are most often made of metal, plastic, or wood. The manufacturing
operations may include milling, drilling, lathing, and polishing.

3. Getting Started
Once you have Pro/Engineer wildfire installed
on your system, there are two options to start
it.
1.The first option is to choose the start button
at the lower left corner of the screen and
select start> Programs> PTC> Pro Engineer.
2.The second option to start Pro/Engineer>
Pro/Engineer wildfire is by double-clicking on
its shortcut icon on the desktop of the
computer.

9. Create Datum Planes
We will now create the first features of the part: three reference planes to locate
it in space. It is not absolutely necessary to have datum planes, but it is a very
good practice, particularly if you are going to make a complex part or assembly.
Datum planes are created using the “Datum Plane” button on the right toolbar, as
shown in Figure. Note that these icons look quite similar to the buttons on the top
toolbar that control the display of datums. What’s the difference?

10. Pro/ENGINEER Feature Overview
Below (and/or to the right of) the datum creation buttons in the right toolbar
are three other groups of buttons. These are shown in Figures 1, 2, and 3. If
you move the cursor over the buttons, the tool tip box will show the button
name.
Two of these menus contain buttons for creating features, organized into the
following categories:

11. Placed Features (Figure 1) - (holes, rounds, shells, ...) These are
features that are created directly on existing solid geometry.
Examples are placing a hole on an existing surface, or creating a
round on an existing edge of a part.

12. Sketched Features (Figure 2) - (extrusions, revolves, sweeps, blends, ..) These
features require the definition of a two-dimensional cross section which is then
manipulated into the third dimension. Although they usually use existing
geometry for references, they do not specifically require this. These features will
involve the use of an important tool called Sketcher.

13. The final group of buttons (Figure 3) is used for editing and modifying existing
features. We will deal with some of these commands (Mirror and Pattern) later in
the Tutorial.

15. Another change is the addition of some new toolbar buttons at the top of the
screen5. See Figure. These are in two groups: a Sketch Display group and a
Sketch Diagnosis group
In the Display group, the four buttons with the eyeballs control display of
dimensions, constraints, the grid (default off), and vertices. Leave these buttons in
their default position (Dimensions, Constraints, Vertices, all turned on). It is
seldom (if ever) that you will need to turn on the grid in Sketcher. The button at the
far left will return you to the default view of the sketch if you should accidentally (or
intentionally) go into 3D view. Buttons in the Diagnosis group will control or launch
functions that can help you identify and fix possible problems in the sketch. For our
first sketch, turn on the Shade Closed Loops and Highlight Open Ends buttons.

16. On the right end of the dashboard are several common tools that appear for all
features. See Figure. These function as follows:
Pause - allow you to temporarily suspend work on this feature so that you can, for
example, create a missing reference like a datum plane, measure something in the
model, etc. When you are finished with the side trip, press the symbol < that
appears here to continue where you left off.
Preview - (default on = checked) this is responsible for the shaded yellow display of
the feature under construction. Uncheck this - all you will see is the feature creation
direction, drag handle, and depth dimension. Turn this back on.
View Geometry (or Verify) - this shows what the geometry will look like when the
feature is fully integrated into the part. Not much happens with this first protrusion.
Press again to return to preview.
Accept and Quit - do just what you expect!

17. This is one of the few times when a middle click does not mean “Accept”, which is a
good thing since inadvertent middle clicks happen often when you are in Sketcher.

19. Differences From Other Parametric Sketching Systems
All sketches are always fully constrained. Pro/Engineer automatically suggests
constraints to all sketch elements as soon as they are created; these are generally
shown in gray and are called weak constraints. Constraints specified by the user are
shown in a brighter color and are called strong constraints. Users may accept the
automatically-chosen weak constraints by invoking the RMB context menu and
selecting the Strong option. A Strong constraint may be weakened by invoking its
context menu and selecting Delete.
Fully (strongly) constrained sketches can still be moved and reshaped. Other CAD
packages consider all dimensions to be locks whereas Pro/Engineer allows the user
to drag and modify even the strong dimensions already specified. To experiment with
a geometry with particular constraints locked, the Lock option can be selected from a
dimension's context menu.
There is no offset. It can be avoided by sketching entities and constraining them with
dimensions and geometrical constraints.
Datum planes have positive and negative sides which are colored differently and
have different behavior.
Pro/E Sketcher is simpler than similar sketchers in some other 3D CAD packages, as
it has relatively few 2D entity toolbar buttons. Other CAD packages such as CATIA
V5 have many more toolbars.

20. Keyboard/mouse shortcuts

21. The user can spin, zoom, and pan the model by moving the mouse while
holding middle mouse button, middle mouse and CTRL key, and middle
mouse and SHIFT key respectively. Fig. illustrates the mouse
functions. The center of the zoom is always at the cursor location. The
view can be scaled by a factor of 2 by holding SHIFT or CTRL key, and
rotating the middle mouse button. Explore each of these functions.

22. A description of the Pro/E screen

23. Pro|ENGINEER creates three default datum planes - FRONT, TOP and
RIGHT. Each datum plane has two sides marked by orange and black
colors. These planes can be visualized by looking at Fig. where the
planes are shaded. In the standard orientation (shown in Figs.), only the
orange sides are visible. The black color appears when the model is
rotated. The orange side is considered to be the active side of the datum
plane. In Figs. 2.2 and 2.5, the default part coordinate system
“PRTCSYS- DEF” is located at the intersection of three datum planes.
The spin center shown in Red, Green and Blue (RGB) color lines helps in
rotating the model

24. INSERT EXTRUDE [Or click
in the feature toolbar – left side]
To select the sketch plane, click Placement (in the dashboard) Define

25. Sketch view set-up window
Pro|ENGINEER brings up “Sketch” window where we define the sketch plane.

26. We are going to sketch the section on the TOP
datum plane.
Pro|ENGINEER highlights different planes as we
move the mouse over them.
Select the TOP datum plane in the graphics
window or in the model tree by clicking on “TOP”
The yellow arrow in the graphics window points
to the view direction. Clicking “Flip” in the sketch
window
reverses the view direction.
Pro|ENGINEER automatically orients the sketch
plane by aligning the outward normal from the
reference (the right datum plane) in the right
direction.
Sketch
The screen changes to the sketcher mode.
Activate “References” window by selecting:

27. SKETCH REFERENCES
The “References” window shows two
references: F1(RIGHT) and
F3(FRONT).
All dimensions are placed with respect
to these two references. If necessary,
additional references can be added to
this list. It is advisable to select the
references before sketching.

28. Holding the middle mouse button and moving the mouse
rotates the model.
Move the mouse holding Middle Mouse
