Photo Realistic Rendering

MODELING OF AMERICAN CHOPPER IN SOLIDWORKS

INTRODUCTION

Solidworks is one of the leading design software in the industry. Majority of OEM's use this software for modeling their products. This was developed by Dassault Systèmes. This is used to create 2D and 3D objects and perform design oriented tasks like assembly and rendering. Solidworks has also a module name Photoview 360 which is soley used for rendering the objects that has been created in solidworks. However this can also done through other third part softwares. This project is focussed on solid modeling of American chopper bike, each and individual bodies seperately. Then assembling it in the solidworks assembly environment. And rendering its photo-realistic image in Photoview360 and SOLIDWORKS VISUALIZE(STAND ALONE RENDERING SYSTEM FOR 3D PARTS AND ASSEMBLIES).

OBJECTIVES:-

• To model individual parts of the Chopper assemblyAssembly of the American chopper in Solidworkks.
• Getting insights of decal,light &scene composition and application.
• Final rendering of the Chopper in photoview 360 and in Solidworks visuFLOW CHART

Basic features used and its nature

Sketch:
The sketch is a 2D representation of the model. These are known as entities in Solidworks. e.g.: line, rectangle, spline, circle, arc etc.

Loft:
The Loft feature allows you to generate complex geometry. It does this by interpolating surfaces between various cross section of the model. These cross sections can be sketches, faces or edges. In the Loft interface the cross sections are considered as Loft profiles.

Dome:
This feature is majorly applied to faces. Select one or more planar or non-planar faces. You can apply dome to faces whose centroid lies outside the face. This allows you to apply domes to irregularly shaped contours.

Extrude Boss/Base:
This feature is used to convert a 2D sketch into 3D model

Extrude Cut:
This feature is used to remove materials from the 3D model. It is just opposite to extrude boss because it cuts a sketch profile while extruding. You can cut in both directions and mainly used for creating holes, channels, slots etc.

Fillet:
This feature creates a rounded internal or external face on the part. You can Fillet all the edges of a face, edges , loops etc.

Split:
This tool is used to project an entity onto other surface or curved or planar faces. You can also split faces on multiple bodies with one command.

Offset:
Offset one or more sketch entities, selected model edges or model faces by specified distance. For e.g. You can offset sketch entities such as splines or arcs, set of model edges, loops and so on. You can offset finite lines, arcs and splines.

Revolve:
Create a sketch that contains one or more profiles and a Centre line or an edge to use as the axis around which the feature revolves.

Dynamic Mirror:
Dynamic mirror, it is used as you sketch the entities, they are mirrored about the pre sketch entity.

Trim entities:
This tool is used to delete or cut unwanted sketch geometry and or can be used to extend geometry to the next intersection.

Patterns:
The pattern tool allows you to create Patterns along a Planar or 3D curve. You can base your pattern on a open curve or on a closed curve such as circle. In the chain part curve driven pattern is used.

Shell:
Used to convert a solid object into a hollow object by deleting the materials inside leaving only the outer surface and the thickness defined by the user.

Combine:
Combine feature is used to manually combine two bodies into a single solid body or surface.

Chamfer:
A cut on the edge or corner of something that makes it slope slightly rather being perfectly sharp edge.

Linear pattern:
Multiplies a feature or a sketch along the specified path in a linear path as per the number of instances specified.

Circular Pattern:
Multiplies a feature or sketch along the specified circle or a axis of rotation as per given number of instances.

Move/Copy Body:
This feature is used to move/copy the body from one place to another place

Mirror:
Mirror is used to mirror a solid object or a sketch by specifing a mirror line or any planes in the modeling or assembly window.

Projected curve:
Peojected curve is a kind of 3D curve which is projected based on the two different 2D sketches.

Sweep:
With the sweep feature we can create a shape by moving a 2D sketch profile along a 2D or 3D sketch path.

Composite curve:
This feature is used to join two curves and make them a single curve. Eg combining a projected curve to another curve etc.

Loft surfaces:
Loft surfaces are surfaces generated by multiple 3D curves or existing edges creating a smooth tangency between the selected curves.

Sweep surfaces:
Sweep surfaces are surfaces that are generated from a section curve positioned along a path.

Fill surface:
The fill surface feature constructs a surface path with any number of sides with in a boundary defined by existing model edges, sketches or curves including composite curves.

Surface Trim:
Primarily used to cut away material from a surface and provides two modes: standard and mutual

Surface Knit:
Surface knit is used to knit two free edges / open edges of the surface together into a single surface.

Mates:
Mates create geometric relationship between the assembly components. As we add mates, we define the allowable directions of linear or rotational motion of the components. We can move a component within its degree of freedom, visualising the assembly behaviour.

Assembly of the American chopper

1)Importing the individual components into the assembly file.
2)Fixing the geometrical loaction of the chassis where all the components will be assembled.
3)Giving all components mates with other components to define its location.
4)Mirroring the Foot pedal to the opposite

Rendering
Once the assembly is fully defined, Now the work is to bring it to life using a proper rendering environment.
This can be done in two methods, PHOTOVIEW360 and SOLIDWORKS VISUALIZE

• Photovie 360 is a in-built module in Solidworks which is capable of rendering a component or assembly inside the solidworks.
• Visualize is a standalone rendering software. Which can provide good results in terms of appearance and ease of use.

Rendered in Photoview360

Below images are rendered in SOLIDWORKS VISUALIZE

CONCLUSION

All components are modelled as per the given guidelines. And assembled in assembly environment accordingly. Then using photoview 360 the chopper was set up in rendering view. After that the model was rendered in the same and imported it into the visualize software and done few more renders.
