Samples of 3D Modeling carried out
with various software packages
Demonstrating proficiency in Mechanical Design

2. Pro/Engineer Samples
The following images present samples of
work carried out during my final year at
university. The objective of this project was
to design a transmission system to deliver
power from a 2.5 hp engine. Solid
modeling was carried out using
Pro/Engineer

3. Various modeling tools were utilized to create complex
geometrical shapes and features
Nuts and Bolts complete with threads
Centrifugal Clutch with springs
and shaft hole

4. Shapes were modeled realistically and made visually
appealing in order to compete against other design teams
Spur Gears with key holes Roller Bearing assembly complete
with cylindrical elements

5. Complex geometry was modeled using various tools
Coupling, nuts and bolts
Shaft with keys
together in exploded view

6. Various components were accurately assembled to create a
transmission
Coupling
Driven
Shaft
Gear
Bearing
Pinion
Bearing
Driving Clutch
Shaft

7. The gear housing was designed based on the placement of
various transmission components.......
Gearbox with openings for various shafts

8. ...And perfectly accommodated with the transmission

9. SolidWorks Samples
The following images present samples of work
carried out during my Co-op placement at the
National Research Council. This was done to
document the design of a test rig in great
detail with all major and minor components.
Solid modeling was carried out using
SolidWorks

10. Small and large components were accurately modeled
Gasoline Port Fuel Injector
Cartridges present
within fuel vaporizer

11. And precisely combined to create sub-assemblies
Cross Sectional and Isometric views: Fuel Injector and Vaporizer
combined with various elements to create passageway for fuel flow

12. Single cylinder research engine and fuel injection system with view of
combustion chamber and internal passages

13. Owing to the large number of components, placement
required a great deal of visualization
Spray Chamber with outer and inner views

14. The positioning of various components and sub-assemblies of
the test rig was studied using blueprints such as this.....
Piping and Instrumentation Diagram of the Test Rig

15. ......To create an complete model of the Test Rig
3D Model of the Test Rig

16. Catia V5 Samples
Over the past few months, I have been
learning to use Catia V5. The following images
are samples of designing I carried out with the
use of tutorials. I have become proficient in
the basic tools and functions of Catia V5 and
will soon gain expertise with advanced
features.

17. I’m capable of creating basic objects using Catia
Water Bottle Wheel

18. As well as entities with varying features
Shapes created during interactive tutorials

19. Capitalize on my talent
