Photo Realistic Rendering
Title of the Project: American Copper Bike
Objective:
To learn SolidWorks by modeling the different parts of the American Chopper Bike and its assembly using different tools like line, circle, spline, extrude, revolve, mirror, fillet etc.
Introduction:
SolidWorks is a professional software used by design engineers in order to create 2D sketch, 3D models, surface models, assembly of the different parts, rendering and many more. It is also helpful to apply different appearances to our models. In this software firstly a 2d sketch is created and the converted that sketch into 3d model and surfacing. After the parts are created then they are assembled together to make them a product. Then we have different other things to do like rendering and different other things according to the necessity.
American Chopper Bike is one of the most popular bike started in 2003. It focuses on Paul Teutul Sr, his son Paul Teutul Jr and their company, Orange County Choppers which is located in Orange County, New York. This Chopper is very interesting because of the differences between the vision and styles between the father and son. They focus on restorations and customizations of choppers built in the US.

Side view
Camera setup view
Top view
Front View
Isometric view
Rendering:
Rendering is the process of creating the photorealistic look of the the model.It is done in two ways
a) Photoview 360
b) Solidworks Visualize
Photoview 360: It is a visualization and rendering solution which is included in the solidworks. It provides a highly interactive environment for viewing designs and creating photorealistic rendering.
Solidworks Visualize: It is a standalone application from solidworks which helps our 3D cad data to create photo quality content from images to animations, interactive web content, and immersive virtual reality to bring our products to life.
Rendered snapshots:
Conclusion:
Hence all the parts of the American Chopper were modelled and assembled using solidworks and the Photo-Realistic Rendering were done using Photoview 360 and Solidworks Visualize.
