American Chopper Bike Assembly and Rendering

AMERICAN CHOPPER BIKE

Objective: To learn and apply different SOLIDWORKS commands/features to design an American Chopper Bike and render it.

Introduction: This report contains details about design of American Chopper bike using SOLIDWORKS, PhotoView 360, SOLIDWORKS Visualize. SOLIDWORKS is a 3d CAD design software and it was used in this project for modeling all the bike components and assemble them using proper mates and relations. PhotoView 360 is a visualization and rendering tool for creating photo-realistic renderings of your designs. SOLIDWORKS Visualize is a tool used to turn your CAD data into realistic photo-quality images.

Design Methodology:

The steps followed in the process are as follows,

Fig.1 Design Methodology Flowchart

As bikes have various components, first we need to design all the components of the bike. Then in order to design the bike, we need to assemble all the parts with proper mates (relations) between them, to form the assembly. Further the assembly is given appropriate appearances and lighting effects to produce photo-realistic rendering images of the assembly.

Tools and Features:

• Chamfer: Chamfer is used to give a sloped or angled corner to otherwise sharp edge.
• Combine: Combine feature allows you to add two bodies together and keep the area that is common to both.
• Dome: As the name suggests, dome feature is used to provide dome shape to surfaces.
• Extrude: Extrude feature allows to form 3D solid body from surface or plane.
• Fillet: Fillet is used to give rounded shape to (internal or external edges) otherwise sharp edges.
• Loft: Loft feature allows you to generate complex geometry in a single feature by specifying cross sections made from faces and profiles of closed sketches.
• Mirror: As the name suggests, mirror feature allows you to create an opposite hand version of a part.
• Pattern: Pattern tool allows you to create patterns of desired parts/sketches along open or closed curves, edges, surfaces etc.
• Projected curve: This tool allows you to create a projected curve, from 2 different curves. The resultant curve is the intersection of surfaces formed by the two curves.
• Revolve: This feature allows you to revolve a closed sketch around a selected axis of rotation to form solid body.
• Shell: Shell tool hollows out a part and creates thin-walled features on all sides, leaving the selected faces open.
• Split surface: As the name suggests, split surface feature allows you to split a surface into two separate surfaces.
• Surface knit: Surface knit feature is used to merge 2 surfaces into one surface.
• Surface loft: Surface loft feature is used to generate complex surfaces by specifying cross sections made from sketches.
• Surface sweep: As the name suggests, sweep surface command allows you to sweep a surface along a given curve, to form a complex surface geometry.
• Sweep: Sweep command is used to sweep a feature along a provided curve to form a solid body.
