Creo Parametric Session-1

Open PTC Creo Parametric 3.0

1) Click on Erased Not Displayed.

• As it erased all the Back end memory of a computer(Memory in RAM)

2)      Select Working Directory before Starting a Model

• Working Directory is a Target Location for Opening & Saving of files.
•  Many ways to set a Working Directory: 1. Before Starting a Model. 2. From Folder Browser ( Folder Browser-Select folder of choice- Right Click- Set Working Directory)

3)  New

• Name
• Uncheck Use Default Template (As Creo Selects Inch By Default)

• OK
•  Select mmns_part_solid (Millimeter/Newton/Seconds)
• OK

It opens as in Trimetric Orientation By Default.

4) Initial Setting required to make in Creo:

• File – Options-Model Display-Default Orientation-Isometric
• File-Options-Sketcher-Sketcher Startup-Check Make Sketch Parallel to plane
•  File-Options-Sketcher -Dimensions Behavior while dragging the section- Check Lock User Dimensions

5) Isometric Orientation and Terminology of Creo 3.0

Above Screenshot illustrates the terminology of Creo.

 Note:   Standard Orientation-  Cntrl D

             Command Through Keyboard- Press Alt

          Rotate Object- Press Scroll and Move the Mouse

          Zoom IN/OUT- Scroll

6) Dimensions In Creo:

There are 3 Types:

• Weak: By Default, weak dimensions are generated.
• Strong:
• Locked:

7) Constraints:

It is nothing but locking the Degree of Freedom of sketcher.

1.       Dimensional Constraints

2.       Geometrical Constraints:

•  Vertical: Make entity vertical
•   Horizontal: Make entity Horizontal
•   Perpendicular: Make two entities 90 degrees to each other
•   Tangent: make two or more entities tangent
•   Midpoint: Midpt of entity
•    Coincidence: Make pt/Line coincidence
•    Symmetric: make symmetry
•    Equal: Make entities equal
•     Parallel: Make entity parallel

If weak dimensions is not present in the sketcher, the sketch is fully Constrained.

Let’s Start with a Sketcher…..

8) Sketch- Select a desired plane( Front/Right/Left)-Ok

Sketcher Mode is Activated.

8.1 Profile Requirements in Creo:

• Profile must be a closed loop. Shaded colour shows it is closed loop. So, Shade closed loops must be Active.

• All Dimensions should be Locked. i.e Sketch should be fully constrained.

• Profile Should not be overlapped. To check, Overlapping Geometry option Must be active. The Red colour shows the geometry is overlapped there. To delete overlapped geometry, Right click on the geometry- pick from list- dlt

•  Profile should not be open. If such profile is open, the Highlight open ends option highlights the open ends.

•  Minimum two References must remain in a single sketch.

            References: Two types of selecting References: 1. Right click on entity and                   references 2.  Ribbon-Ribbon-References                      

9) To trim an unwanted geometry, Ribbon- Delete Segment

10) Saving of Files:

Every time Creo saves the file with a new version. Every time new file is created with a newer version.

•         File- Save- Ok
•        To delete all versions: File- Manage File- Delete all Versions
•        To delete old version: File-Manage File- Delete Old Version

11) In Graphics Toolbar:

• Datum Display: To Hide Datum Planes/Axis
• Also we can hide from model tree
• To Rotate about point: Select spin center
•  Pan: Shift+ Press Scroll- Move in Graphics Window
•  Scroll: Zoom In/Out
• Turn: OFF Spin Center
•  Zoom: Cntrl Press+Scroll Press+Move In a graphics window

12) Colour Codes :

•  Wireframe Green  - Component Selection
•   Dark Green             - Surface Selection
•  Orange                     - Preview Geometry of Component
•   Purple                       - For Assembly( Partially Constraint Component)
•  Selection Sequence: Component- Face- Edge-Point
•  Direct Selection : Alt+Point/Edge/Face

13)Model Tree:

Set of features in order of creation.

• Tree Filter: For Displaying Specific features
•  Show Layer Tree
•  Layer tree- To Show/Hide All Planes

14)Types of Selection:

• Direct Selection( In Sequence,Left click on the Component/ face/Edge/Point)
• Range Selection (Shift Press same as in Windows)
• Multiple Selection( Cntl Press and select entities to select same as in windows)
• Query Selection( Right click on part for inside part selection/ Hold Left click and Pick from list)
•  Smart Selection( Smart Filter at Right Bottom corner)

15)Editing Sketch:

• From Tree- Right click on sketch- Edit Definition
• Or Double click on feature

16)  Regeneration:

• After editing the dimension, it will automatically updated/Regenerated.
•  If not Regenerated automatically, Select Regenerate option from Ribbon.

17)  Delete And Supressed items

Delete	Supress
It is permanent.	It is temporary.
It cannot be Resumed.	It can be Resumed.
It is permanent removal form graphics window.	Suppressing an item removes it from graphics window and regeneration cycle.
Delete-options- Suspend	To recover Supressed- Resume
	In case of assembly- Supress- freeze

18)   To change plane: Ribbbon- Sketch setup

19)   Datum Plane/Axis/Point for generating plane/axis/point
