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) softwhere like SOLIDWORKS 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 modelling them to final rendering of the assembly to give a photo realistic view.
METHODOLOGY:-
- Part Modelling
- Assembly
- Rendering
PART MODELLING:-
In part modelling first the 2D sketch of the part is sketched using the tools 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 feature is used to expand the object in 3d according to the 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 surface between various cross-section of a model.These cross-section can be sketches,faces,or edges.
SPLIT:This is used to split single solid part into two solid parts.it is used to project an entity onto other surfaces or curved/planar 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 solid part and so removes the inner parta.It is also used to reduce the specific thickness.
COMBINE:combine tool is used to make integration 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 beign a perfect square .
LINEAR PATTERN:The linear parent is used to create a different nummber of instances required to create the pattern linearly.
CURVE DRIVEN PATTERN:Curve driven pattern is used to make any pattern which follower by the curve is sketched before.
CIRCULAR PATTEN:Circular pattern is a feature used to makeot 3D feature into circlular pattern according to number of insistences.
REVOLVE BOSS BASE: Revolve feature is used to make cylindrical or circular 3D extrude 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 plane.
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.
BOUNDARY SURFACE:Boundary surface is used to make a surface in between two finished surfaces.
LOFT SURFACE:Loft surface is used to make loft in between two profiles along with guide path.
KNIT SURFACE:Knit surface is used to knit the two free edges or open edges of the surface together also it reduces the gap between the two edges of the surface.
SURFACE TRIM:-Primarily used to cut away material from a surface and provides two modes STANDARD and MUTUAL.
PROJECTION CURVE:Projection curve is a 3D curve which is projected on the basic of the two different planes.
BLOCKS:You can make save,edit and insert blocks from the drawing items and sketch entities that you use often such as standard notes,title blocks,label positions and so on you can attach blocks to geometry or to drawing views
TRIM ENTITIES:It is used to trim the unwanted lines or extended entities in the sketch
APPEARANCES: An appearances defines visual properties of the model including colour and texture.Appearences do not affect physical propertites which are defined by materials every materials is assigned as default apperance.
ASSEMBLY:
Assembly is most often reffered 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 rebuild the document.
ASSEMBLY APPROACHES IN SOLIDWORKS
- TOP-DOWN APPROACH
- BOTTOM-UP APPROACH
RENDERING
Rendering or image synthesis is the automatic process of generating a photorealistic or non-photorealistic image from a 2D or 3D model using a computer program.The resulting image is referred to as the render.

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
FEATURE USED
- LOFT BOSS
- EXTRUDE BOSS
- EXTRUDE CUT
- DOME
- SPLIT

Kickstand for this bike is of a very simple kind made 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.
FRONT FENDER
FEATURE USED
- OFFSET ENTITIES
- TRIM ENTITIES
- REVOLVE BOSS
- DYNAMIC MIRROR
- SPLIT
- FILLETS
- APPEARANCE
The 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
- OFFSET ENTITIES
- TRIM ENTITIES
- REVOLVE BOSS

ASSEMBLED AMERICAN CHOPPER
Assembly is most often referred 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 ie.The rebulid option will automatically take place or else it will ask the user to rebuild the document.
The American chopper is assembled using the feature called 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.
- CONCENTRIC
- COINCIDENT
- PARALLEL
- TANGENT
- 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 PHOTOVIEW 360 and SOLIDWORKS VISUALIZE.
