Creo Extrude Tutorial
Part 1: Setup and Initial Extrude
1. Open Creo Parametric 2.0
2.
3. Setting Working Directory (Optional): Automatically saves all work in the folder user has chosen
a. Click on the Icon Select Working Directory
b. Navigate to the folder you wish to save in > Select folder > HOLD Right Mouse Button > Select Set
Working Directory
Dialogue Box: Provides instructions on what software would
like you to select or shows error messages
Built-In Internet/Computer
Navigator Window: This
will show the user files on
the computer/external
hard drives and browse the
internet.
Standard Window Menus: I.E New, Open,
Minimize, Maximize, ETC
4. Select New
a. A pop window will open and show different types of drawings the user can create. Listed are the
types of drawings can be created in Creo.
5. We will be creating a 3D part.
a. Select Part
b. Name the file extrudetutorial
i. File names need to be one string of characters. (NO SPACES)
ii. It is important to provide a consistent filing system for your file names in order to keep
drawings and folders organized. I.E DWG01, DWG02, DWG03, etc. Each assignment will have
two files, it is important to have a filing system in order to keep these files together because
they are dependent upon each other and it is just easier to find them.
c. Click OK (if an error comes up you check your file name. Remember NO SPACES)
Types of Drawings
1. Sketch: Allows the user to create 2D
objects
2. Part: Allows the user to create 3D shapes
(we will be using this a lot)
3. Assembly: Allows users to put multiple
Part files together to create a larger
object.
4. Drawing: Allows users to layout Part files
in orthographic form
5. Format: Allows users to create forms that
can be used multiple times. I.E Title Blocks
6. Other Drawing Types we will not be using
6. The following screen should appear.
7. Creo Part Basics
a. Datums: Imaginery defined planes, edges, axis, points in space to help define location of a solid model
i. Each part starts with 3 Default Datums (Note: Each datum has 2 dimensons)
1. Right (Dimensions: Height and Depth)
2. Top (Dimensions: Length and Depth)
3. Front (Dimensions: Length and Height)
ii. All parts are predefined in inch scale
8. Solid Model Navigation Tools
a. Mouse
i. Left Mouse Button: Selects objects
ii. Roll Bar: Zooms in and out on the model screen.
iii. Hold Down Roll Bar (Middle Mouse Button): Rotates Model
iv. Hold Right Mouse Button Down: Gives pop out menu based on the design tab.
b. Hotkeys
i. a= Autoscale
ii. i= Isometric
iii. d= Turns Datums on and off
File Name Tabs for various operations on the solid model
Model Tree: Shows all of the operations you
have created on the solid model. Workspace: Where the model is being built.
9. Various ways to create Solid Models (Note all processes can ADD and Subtract material)
a. Extrusion: Elongating a 2D Closed Profile in a linear distance (Length, Height, or Depth depending on the
orientation of the 2D Closed Profile)
b. Revolve: Rotating a 2D Closed Profile around an axis
c. Sweep: Elongating of a 2D Closed Profile along a user defined path
d. Blend: Connection of multiple profiles that are on parallel datum’s
10. Creating an Extruded Model
a. First step is to create a 2D Closed Profile this is called a Sketch. There are two types to create a Sketch
i. External Sketch: This seperates the Sketch and the Extrude operations. We will be avoiding this
method.
ii. Internal Sketch: This embeds the Sketch into the Extrude operation. Keeping the Sketch and Extrude
linked. Also called the Parent/Child Relationship.
b. On the Info bar at the top of the screen select the Tab Model > Select the Extrude icon.
c. The Extrude Info Bar
Solid Model:
Extrudes model
as a solid entity.
Surface: Extrudes profile
as surface. Makes inside
hollow
Extrusion Types and Distance
1. Blind: User Defined
Distance in one
direction of the datum
2. Symmetric About
Datum: Extrudes
model on both sides on
datum based on user
defined distance
3. Extrude to Surface,
Datum, Point, and
Edge: User selects a
predefined entity to
extrude too.
User Defined Distance
Flips Extrusion from one side of
the datum to the other

d. In the work area (black background) HOLD your Right Mouse Button down > select Define Internal Sketch
e. The Sketch Pop Window will appear
f. Select the Front Datum by either selecting it in the Workspace or in the Model Tree. The information the
Sketch Menu will fill in. (Do not worry about what the rest of it means)
g. Press Sketch in the Sketch Pop Window
h. The screen should rotate so the datum is perpendiculiar to your view
i. Info Bar will change to the sketching window. These are the tools you will use to draw your 2D Closed Profile
j. Select the Line Tool > starting at the Origin (center of the screen) > Left Click once to start the line. To set the
line Left Click at the endpoint of the line. Draw the following shape do not worry about the length of the lines.
Avoid making lines the same length. The Software will place an L next to a lines that are equal length.
k. Once the shape is closed click the Middle Mouse Button to exit out of the line tool. The profile should be
shaded in creating a Closed Profile.
a. Types of Profiles
i. Closed Profile: Shaded informing on solid shape of geometry. Can be Extruded
ii. Open Profile: Non-Shaded form of geometry. Collection of lines that do not
form a shape or have intersecting lines. Cannot be Extruded
If not then you must add an extra line to complete the shape or if you have to many lines use the Delete
Segement Icon under Editing. You can either click Left Mouse Key on the line or hold the Left Mouse Key and
drag over the line(s) you want to delete.
l. Press the letter A to autoscale the screen. This should center and zoom in your part. This wil ltake you from
the Sketch Tab to Model Tab. Reclick on the Sketch Tab
m. To place your own dimensiong click on the Normal Icon.
There are two ways to place the linear dimension
1. Left Click once on the line you want to place a dimension on and Middle Mouse Button
2. Left Click once on one line then Left Click on a parallel dimension then Middle Mouse Button
to place. Note: If you select two non-parallel lines then an angle dimension will appear.
If you place to many dimensions than error menu will appear. This means you are Over Constrained. Select
one of the options, the option will highlight on the part and hit delete.
DO NOT worry about the values. They do not
need to be the same as the tutorial yet. The
software will automatically place dimensions.
These are Weak Dimensions and appear in
Blue. If you double click on the dimension and
change the value it will become a Strong
Dimension and appear in Red
n. Place and change the dimensions as you see below. Rule of thumb is to change the smaller dimensions first
and work out to the larger ones. The screen should rezoom as the part gets smaller. If not use the Hotkey a
to autoscale.
o. Click the Green Check button to accept the sketch profile. (Red X will cancel the profile and delete everything
you have created.)
p. Place cursor on the part > Hold the Middle Mouse Button down > move the mouse to rotate the part.
q. Press i to rotate the part into an Isometric
r. Press a to Autoscale the part
s. In the User Defined Distance in the info bar type in the distance of 4
t. Click the Green Check to complete the Extrude. (Red X will delete the part)
11. Change the View State
a. Click on the Tab View > Click on Display Style Icon > A list will appear >
i. Shading with Edges= Shades objects and makes edges thick so they standout
ii. Shading with Reflections= Gives a rendered image as if a light was shining on the part
iii. Shading = Default, Colors the image and provides minor shading of surfaces to help define orientation
iv. Hidden Line= Shows object lines and hidden lines without solid color
v. No Hidden= Only shows object lines without solid color
vi. Wireframe= Shows all lines object and hidden as solid lines
Try a few of these types out to see what they look like. Rotate the part to see the differences on the object
Hotkey d= Click Letter d to turn off and on datum planes, axis, points, etc.
When finished hit Letter i (Isometric) and a (Autoscale) to reset the object.

Part 2: Adding a Cut
12. Goto Model Tab > Click on Extrude Icon > Hold Right Mouse Button in Work Area > Select Define Internal Sketch >
Select the Surface shown below > Click Sketch > View will rotate surface perpendiculiar to your view
13. Goto View Tab > Display Style > Hidden Line
14. Setup References > Refernces allow the user to select known edges to snap to
a. Goto Sketch Tab > Click on the References Icon under Setup ( First column on the info bar)
Pop up menu should appear. This will list all of the edges selected. User can select
as many edges as they need (We are adding more than needed here).
Select all of the edges of the part.
A Datum Line (Dashed Blue Line) Will appear on top of each of the edges
User can add Reference lines at any time.
Image Should look as follows
15. Use Sketching Tool > Rectangle and draw a rectangle starting from the top edge. Cursor should snap to the top edge
because of the reference line. Without the reference line the cursor would not snap to the top edge. Simliar to what
is shown > Click Middle Mouse Button to exit out of the Rectangle Tool. Remember the dimensions do not need to be
the same as the tutorials yet. Software will automatically dimension and the profile will shade in. The sketch will not
shade in if it is an open profile
16. Change the dimension using the Normal Tool to what is shown and change the values to the same as what is shown.
Middle Mouse Button will exit out of the Normal Tool. Note the dimensions you are changing to are not the only set
that will work for this part. Remember this is practice.
17. Click the Green Check to Exit Out of the Extrude > Press Letter i and a
18. If the Extrude Preview dissappears click on the Extrude Tab to reshow it.
19. Change the View Display back to Shaded. View > Display Style > Shading
20. The Profile is shown as adding material. Click the Subtract Material Icon on the Extrude Info Bar and Flip on Datum to
place the cut into the part. Change the Extrude Value to 1.00
21. Part should look as follows
22. Modifying Sketch Size while in the Extrude Menu Bar
a. Click on Placement Tab > Edit > This will place you back into the sketch. Change the values as follows

b. Select your surface > Click Ok from the floating Select Menu
Save File
Part 5 File Cleanup
35. Everytime the save button is pressed the software will create a new file. For example if I have saved this file 3 times on
in my Working Directory I will have
EXTRUDETUTORIAL.prt.1
EXTRUDETUTORIAL.prt.2
EXTRUDETUTORIAL.prt.3
We only want to keep the most recent. There are two ways to clean this up
Option 1: Exiting Creo 2.0 > Navigate to the working directory in the C: Drive or External Folder > Select all of the files
except for the most recent one and delete. Be careful not to delete everything
Option 2: While in Creo 2.0 > Goto the File Tab > Manage Files > Delete Old Versions > Type in the file name if it does
not apear > Click Green Check to accept or Red X to Cancel
36. We also need to cleanup the Temp Folder. Doing this will help the software and computer run better.
a. While in Creo 2.0 > Goto File Tab > Manage Session > Erase Not Displayed > A pop-up window will appear >
Click Ok. (If nothing appears there is nothing to erase you are fine.)
Note: Both of these steps should be completed on a regular basis (Once or
Twice a week). Not doing this will use up harddrive space making it so you
cannot save and will slow the computer down.
