Creo
• What is Creo ?
 Creo is the Creativity of new products.
 It can able Engineering Design, Analysis, Manufacturing.
 Revolution in the CAD world introducing.
 Parametric ,Feature based , Associative solid Modeling.
 It is developed by PTC based USA 1987.
 Latest release Creo 2.0

2. Modules TERVEZOI
 Sketcher
 Part Modelling
 Assembly
 Surface
 Sheet Metal
 Detailing

3. • Sketcher Module TERVEZOI
 Sketcher Entities
Line Rectangle
Circles Arcs
Ellipse Splines etc…
 Dimensions attached to the Entities.
 Constraints can be added
Equality Tangency
Symmetry Collinear etc…

6. TERVEZOI
Part Modelling
 Its convert 2D to 3D based on the sketch
 Creates a part from a sketch through solid feature based
Modeling.
 Features such as extrusion, revolve, sweep, blend, swept
blend, etc…

7. TERVEZOI
extrude REVOLVE
 It is based on a two dimensional  A revolve feature to revolve
sketch. a sketch about an axis of
revolution(0 to 360)
 It linearly extrudes a sketch  Its easy to create shaft,
perpendicular to the sketching plane cylindrical objects
to create or remove material

8. TERVEZOI
HOLES
 A hollow place in a solid
 It creates standard holes and also manual holes
 Linear ,coaxial , radial , countersink , counter bore

9. TERVEZOI

10. TERVEZOI
SHELL
 The shell feature hollows out the inside of a solid
• model, leaving a shell of a specified wall thickness.

11. TERVEZOI
PATTERN
 A component arrangement between the row and columns at a
equal distance.
 It can able to create axial ,direction ,dimension , curve , fill ,
reference pattern , also..
Direction pattern
Dimension pattern

12. TERVEZOI
Axis pattern
fill pattern
curve pattern

13. TERVEZOI
Advanced features
 Sweep
 Blend
 Swept blend
 Variable section sweep
 Helical sweep
 Toroidal bend etc..
•

14. TERVEZOI
sweep
 A constant section passing through a trajectory is called
sweep…
 It can able to create pipes , wires , etc…

15. TERVEZOI
Blend
 A blend feature consists of a series of parallel sketches.
 It must contain two or more sections. It can reference previous
geometry from section to section. And also contains same
number of entities

16. TERVEZOI
Swept blend
 A swept blend is a mixture of sweep and blend multiple
sections passing through a trajectory
 It must have two sections.

19. TERVEZOI
Variable section sweep
 A constant section uses one or more trajectories can change
shape and orientation along the trajectory.

20. TERVEZOI
Helical sweep
 Helical sweeps can be used to create springs , threads etc.

21. TERVEZOI
Toroidal bend
 To bend a flat solid part into a Toroidal (revolved) shape using
the Toroidal Bend tool .
•
 The Toroidal Bend tool transforms solids, nonsolid surfaces,
or datum curves into Toroidal (revolved) shapes. For example,
you could use this functionality to create an automobile tire
from flat geometry

24. TERVEZOI
Assembly Modeling
 Assembly is a combination of two or more components using
parametric relationship

34. TERVEZOI
Sheet metal
 Lets design and creates the complex parts in sheet metal
 Cuts, Walls, Ribs, Punches, Corner relief are easily to makes
in SHEET METAL

35. TERVEZOI

36. TERVEZOI

37. TERVEZOI
Detailing
 Automatically creates 2D orthographic, isometric, auxiliary,
sectional and detail views of 3D model or assembly.
 It can able to automatically generated bill of materials and
balloons
 Generates dimensions , notes , tolerance , etc..
