Photo Realistic Rendering

MODELLING AND VISUALIZATION OF AN AMERICAN CHOPPER USING SOLIDWORKS

Objective:

The main objective of this project is to model the required parts for the American Chopper, assemble all the parts and render the assembled chopper with the help of solidworks visualize.

Introduction:

Solidworks is a software which is used for planning, grabbing in visual ideas, modelling, feasibility, assessment, prototyping, and project management. This software is used in designing and building of mechanical, software and electrical elements. This gives us more efficiency in building any part and brief idea of how the final element will be the end product. We use solidworks software to design each part required for the American chopper, then the assembly is made simple using the same solid works software, for rendering purpose, the solidworks visualize software is used where it helps in rendering the assembled American chopper in a smooth way.

Design methodology/approach:

Description:

Chassis:

It forms the main skeleton of the chopper, all the components are mounted to the chassis

Features and tools used while designing chassis:

• Sketch
• Offset entities
• Convert entities
• Projected curve
• Create plane
• Extruded boss
• Revolved boss
• Swept boss
• Extruded cut
• Fillet
• Chamfer
• Combine
• Trim entities
• Mirror
• Composite curve
• Split tool

Sketch:

It gives us a 2D representation of the part to be built in different planes with the help of different sketch tools like lines, circle rectangle, spline, arc, straight slots and so on. Later the sketch will be taken out to build a 3D part

Offset entities:

It adds sketch entities by offsetting faces, edges, curves or sketch entities at a specified distance

Convert entities:

It converts selected model edges or sketch entities into sketch segments.

Projected curve:

It is used to project a curve in case of a complicated curve which cannot be created using single plane, it can only be created with the help of multiple planes, and finally the required curve can be projected.

Create plane:

This feature helps us to create a new plane at the required position with the help of some options and dimensions.

Extruded boss:

This feature is used to produce a 3D structure with the 2D sketch, this can be changed to required direction and dimensions also.

Revolved boss:

This feature is used to produce a revolved body to the part by the available 2D sketch, it can also be restricted to some required angles.

Swept boss:

This feature sweeps a closed profile along an open or closed path to create a solid feature.

Extruded cut:

This feature cuts the solid model by extruding a sketched profile in one or two directions.

Fillet:

This feature creates a rounded internal or external face along one or more edges in solid or surface feature.

Chamfer:

This feature is also as same as fillet but here there are options to create angle and distance as required at the edges:

Combine:

This feature is used to combine the body’s all together so the design gets smooth view and it can also be differentiated for some specified parts

Trim entities:

This feature is used to trim of the portion which is not required in the sketch.

Mirror:

This feature is used to get the same surface or body on the other side, the reference can used as a plane or line, the modelling is made easier with help of this option.

Composite curve:

This feature helps us to attach the two broken curves together so that the part is made easier to design.

Split tool:

This feature is used to split the unnecessary portion from the solid body and cut them out, so that we can get a good shape of the part.

• Each part has been built separately, to learn the complete procedure of creating a part.
• Assembly is also learnt by assembling all the parts together with some assembly tools.
• This model is built to learn the standard tools used in solidworks and solidworks visualize.

The final rendering is executed to get the final camera view and other standard views of the American chopper in various scenes.
