Photo Realistic Rendering

MODLLING AND RENDERING OF AMERICAN CHOPPER USING SOLID WORKS  :

OBJECTIVE:

• To Create Individual Solid Parts Of American chopper Using Solid Works 
• How To Assemble Individual Solid Parts Of Chopper
• Applications Of Decals , Lights, and Camera etc
• Createing a Photorealistic Rendered Images of American Chopper Using Photo360 and Visuvalization . 

INTRODUCTION:

Solid Works is a one of the prominent modelling software. This software is mainly used to model 3D parts using 2d sketches. It has photoview 360 which helps in rendering the final model of chopper and also we can decied the look and material of the part and assembly in solid works. In this project we learnt the detailed design of chopper parts and assembly of chopper and finally the rendering of american chopper after the assembly.

 Design Methodolgy/Approch:

Kick Stand:

It is also know as side stand . It is used to support the american chopper when it was in resting stage.

Features Used to Create Kick Stand :

• Sketch
• Loft
• Dome
• Extured boss
• Extrued cut
• fillet 
• split

Sketch:

The sketch is a 2d repserentation of the model.These are entitles in solid works e.g: line, circle and arc etc.

Loft:

Loft feature allows to generate complex geometry in single feature by interpolating surface between various cross section of a model these cross section can be face or edge.

Dome:

Dome feature gives smooth face on profile you can apply dome to face whose centroid lies outside  the face .This allows you to apply dome to irregular contours.

Extured Cut:

Extrude cut is used to remove materials from the 3D models . It is just opposite to Extrude Boss feature you can cut it both directions and mainly used for creating holes, slots etc

Extured Boss :

Extrude is a type of feature to convert 2D sketch into 3D model.

Fillet :

Fillet creat round internal and external face of parts you can fillet number of faces and edges .

Split :

Split tool used to project an entity (sketch, solid, surface, face, plane or surface spline) onto other surface or curved face you are able to split faces on multiple bodies by this command

Procedure To create a 3D model of kickstand :

• Open solid works and create new model
• Select mid plane (Right plane) draw sketch on it
• Then the 2D sketch is created in the front plane and dimensions are given to the sketch to fully define we will use trim and spline commands are used
• Then create two new planes and the ellipse are drawn on the new planes as per requirements
• Then use loft command to create loft for kickstand
• Then do extrude cut command to remove unwanted parts for the
  stand

 Transmission Belt :

 Transmission belt in the chopper is used to tansmit power from engine  to gear box

Features used to create transmission belt:

• sketch
• offset
• fillet
• extrude
• appereance

Offset :

offset one or more sketch entities select model edge or model face by a specified distance for example offset sketch entities such as lines, arcs and splines

Procedures followed to create a model of Transmission belt :

• Open solid works software and create new model
• Select front plane and draw a sketch
• The 2D sketch plane is created in front plane and dimensions relations are given to the sketch and sketch the offset command use to duplicate sketch to some distance.
• After the process extrude the sketch from 2D to 3D model.
• Then apply the fillets as per requirements of the transmission belt
• After that give appearance to transmission belt and save the model.

FRONT FENDER :

Front fender is part mounted on the fork above the wheel to protect the rider and the chopper other parts from debrisis and foreign particals .

Features used to create front fender :

• sketch

Revolve :

To create revolve feature u must have one or more profiles and center line to use axis around which the feature revolve tools .

Trim entities :

select trim based on the entities you want to trim All trim types are available for 2D sketches and 2D sketches on 3D planes and you can use power trim

Dynamic Mirror:

Blocks :

You can edit block and insert blocks for drawings items and sketch entities such as standard notes tittle blocks label positions and so on you can attach blocks to geometry or u can insert blocks into sheet formats .

Process to Create a block :

1. create a sketch
2. click make blocks (block toolbar)
3. Select sketch to make blocks
4. repeat step once again
5. with sketch in edit mode add the necessary relations
6. save the part

Pattern :

curve driven pattern tool allows to create pattern along 3Dcurve u can do a open or closed curve such as circle in the chains parts curve driven pattern is used

Mirror :
By using mirror face with a mid-plane selected only the chosen within the revolve will be mirrored. mirroring bodies can be used whether in a singleor multi body part and allows you to select solid geomentry instead of the features and faces in a body In the fork part  the one part of the fork is
created and the other part is mirrored .Then the parts are manually combined.

Project curve :

Project curve is the kind of 3D cure which is projected on the basis of the two different 2D sketches

Sweep :

Filled surface :

Filled surface feature constructs surface path with any number of sides within a boundary defined by existing model edge sketches or curves including composite curves

Surface trim :

Primarily used to cut away material from a surface and provide two modes standard and mutual

Surface knit :

Surface knit is used to knit the two free edge of the surface together. also it reduce the gap between the two edges of the surface

Assembly of chopper:

•  Initially the chassis part is inserted in the assembly by using insert parts in the option after that the part is inserted in the assembly make it fix the chassis
•  After That the other parts of the chopper are inserted into the assembly and give possible mate conditions

Features used to assemble chopper :

•  Mates
• Insert part

Mates :
Mates create geometric relationships between assembly components as we add mates we define the allowable direction of linear or rotational motion of the component we can move a component within degrees of freedom visualizing the assembly behaviour

Rendering:

•  Rendering is the process of creating realistic images of the
  photorealistic model with the environment.
•  rendering can be done in two ways in solidworks.
•  Photoview 360
•  Solidworks visualize.
•  In photorealistic model some of the mate conditions and positions are
  changed to render realistic model.

Photoview 360 :

Solid Visualization :

Conclusion:

•  The parts of the chopper are modeled.
•  The parts are inserted to assembly environment and the chopper is assembled.
• The realistic image was rendered with the use of the photoview 360 and solidworks visualize.
