Photo Realistic Rendering
DESIGN OF AMERICAN CHOPPER USING SOLIDWORKS
OBJECTIVE
The objective of the project is to model an AMERICAN CHOPPER using CAD(computer aided drafting)solidwhere like SOLID
WORKS and to render it with SOLIDWORKS VISUALIZE to create a photorealistic view of it.
INTRODUCTION
This project explains the designing of American chopper using CAD software SOLIDWORKS from sketching the parts and
modeling them to final rendering of the assembly to give a photo realistic view.
METHODOLOGY
• Part Modelling
• Assembly
• Rendering
PART MODELLING
In part modeling first the 2D sketch of the part is sketched using the tool in the sketch tab and then the 2D sketch is
converted into 3D part using features in the features tab.
FEATURES USED
Boss Extrude :- This features is used to expand the object in 3d according to sketch plane
Extrude Cut : This feature is used to cut / move the 3D object in linear path according to sketch.
Fillet : This is a feature used for making round internal or external edges to avoid sharp edges and make it smooth.
Lofted Boss/Base : This is a feature used to achieve complex shapes. It does this by interpolating aurface between
various cross section of a model.These cross section can be sketches,faces or edges.
Split : This is used to split angles solid part into two solid parts into two solid parts . it is used to project an entity onto
other surfaces or curved/planae faces.
Dome : Dome is a feature used to make dome shaped extrude including elliptical dome.
Shell : Shell feature is used to make to hollow space in solid part by selecting outer wall of the solidpart and so removes
the inner part . It is also used to reduce the specific thickness.
Combine : combine tool is used to make intergration of two solid parts which intersect each other as same solid part.
Chamfer : Chamfer is used to make a sharp edge or corner slightly trapered rather than being a pefect square.
Linear Pattern : The linear pattern is used to create a different numner of instances required to create the pattern
linearly.
Curve Driven Pattern : Curve driven pattern is a feature used to make any pattern which follower by the curve is
sketched before.
Circular Pattern : Circular pattern is a feature used to make 3D feature into circular pattern according to number of
instances.
Revolve Boss Base : Revolve feature is used to make cylindrical or circular 3D extrude along with along with along with
a given reference axis as per drawn sketch.
Revolve Cut : Revolve cut is used to cut or reduce the extrude of cylindrical round surface.
Move/Copy Body : This feature is used to move/ copy the 3D body to one place to another place.
Mirror : Mirror is used to mirror a feature or body by reference of the selected place.
Sweep : This feature is used to sweep any kind of fully defined sketch along with the path.
Sweep Cut : Sweep cut is same as sweep feature but its directly proportional to sweep which makes a cut along with the
sweep path.
Sweep Surface : It is used to make a surface along with a path the curve is driven.
Assembly
Assembly is most often reffred to putting components together in an assembly line,but more specifically ,it refers to
creating a complete product that performs an intended function. Changes in the component are automatically reflected
in the assembly i.e The rebuild option will automatically take place or else it will ask the user to rebuid the document.
Assembly Approaches In Solidworks
• Top-Down Approach
• Bottom-Up Approach
Rendering
Rendering or image synthesis is the automatic process of generating a photo realistic image from a 2D or 3D model
using a computr program .The resulting image is reffered to as the render.

DESCRIPTION :
Transmission Belt
Features Used
1. Offset Entities

4. Appearances
This transmission belt is designed to adapt to the two pulleys created on one side of the engine block. It is a simple model
created using very fewer tools like line, curve and extrude boss/base
Kick Stand

1. Loft Boss
2. Extrude Boss
3. Extrude Cut
4. Dome
5. Split
6. Fillets

Kickstand for this bike is of a very simple kind make by the application of sweep feature. An opening is kept for it to the
chassis and the dome is applied at the ends of the kickstand.

5. Split
6. Fillets
7. Appearance
Front fender for this bike is designed simply by revolving the cross section and cutting away material at the end to make
it pointed. Revolve and split tools are the most used tools here.
Rear Fender
Feature Used :
1. Offset Entities
2. Trim entities
3. Revolve Boss
4. Split
5. Fillets
6. Appearance
The rear fender is thicker but shorter compared to the front fender. It doesn't have a pointed end like the front fender,
rather rounded end as the idea of sketch ,Revolve and split tools are the most used tools here
Chain
Feature Used:
1. Trim entities
2. fillet
3. Blocks
4. Linear Patters
5. Appearances
It is the most complex part of the whole design project .it consist of 390 bodies including sperate bodies for all the inner
plates, outer plates and the pins. The major features used in the parts is the curve driven pattern which allows each
instance of the chain parts to follow the curv driven initially for the chain. It is essential to keep all tha elements of this
chain as a seperate body because it has to rotate along the curve and around the procket which is possible if it is merged
to make a single body
Oil Tank
Feature Used:
1. Boss extrude
2. Fillet

These are two pedels, left and right, Among them , only the right pedel was sketched and designed in the part design
envioenment and the left was made using the in -context features of the assembly enviornmaent. It is designed to sit into

Assembled American Chopper
Assembly is most often refered to putting components together in an assembly line ,but more specially it refers to
creating a complete product that performs an intended function.changes in the component are automatially reflected
in the assembly ie. The rebuild option will automatically takeplace or else it will ask the user to rebuld the document.
American chopper is assembled using the feature valled mates.each and every part is mated with the other or the base
part with specific relation .some relations that are used to mate the parts of american chopper are mentioned below.
1. Concentric
2. Coincident
3. Parallel
4. Tangent
5. width
Final Renders Of American Chopper
Conclusion
Thus the parts of the american chopper are designed and assembled using SOLIDWORKS and are rendered to
Photorealistic images using PHOTO VIEW 360 and SOLIDWORK VISUALIZE
