Photo Realistic Rendering

AIM

1)To design and model an American chopper using Solidworks

2)To assemble all the parts of the American chopper

3)To do photorealistic rendering using Solidworks Visualize or Photoview 360

INTRODUCTION

A chopper is a type of custom motorcycles which emerged in California in the late 1950s. The chopper is perhaps the most extreme of all custom styles, often using radically modified steering angles and lengthened forks for a stretched-out appearance.

SOLID MODELLING

A part is made from a sketch using solid feature modelling. Most of the parts are made using this.

SURFACE MODELLING

A part is made using surface features in Solidworks. Gas Tank is made by surface modelling.
