Photo Realistic Rendering

PROJECT : MODELLING OF AMERICAN CHOPPER USING SOLIDWORK

INTRODUCTION:

The Solidworks is a CAD software which is a mechanical design automation application that lets designer quickly sketch out ideas, experiment and feature & dimension , and produce model and detailed drawing this software is mainly using 2D sketch.

Parts are basic building blocks in the solidworks software . Assemblies contain parts or other assemblies called subassemblies. Solidworks model consists of 3D geometery that define edge face and surface. The solidwork software lets us design models quickly and precisely. It has other ADD-in feature like photoview360which helpin rendering of final models to make it look photorealistic.

In this project we learnt about detailed design of AM chopper parts and assembling them and rendering the final chopper after the assembly.

OBJECTIVES:

The main objectives of this projects are :-

• To create individual parts of chopper using solidworks.
• To assemble all the individual parts into a chopper.
• To know the application of decals, light , camera,etc.
• To create Photorealistic model and render it using Photoview 360 and solidworks visualize.

DESIGN METHODOLOGY/ APPROACH

DESCRIPTION

TRANSMISSION BELT

This is used to tansmit power from engine to gear box.

FEATURE/TOOL USE :

• SKETCH
• OFFSET
• EXTRUDE
• FILLET
• APPERANCE

SKETCH:- A Sketch is a 2D profile or cross section. to create 2D sketch, we use a plane or a planer face .It is a 2d representation of the model sketch of any model can be creates by using various commands such as line, circle ,spline arc etc

OFFSET :- It is parallel profile with a specific distance of the original sketch entities. If the original entity changes then the offset entity also change when we rebuild the model.

EXTRUDE :- Extrude a sketchor selected sketch contours in one or two direction to create solid feature.

FILLET :- Create a rounded internal or external face along one or more edge on a solid or surface feature, fillets can be of constant or variable size.

APPEARANCES :- It is an application of colour material i.e plastic, metal ,rubber, glass, decal as per requirement of model we select specific looks in real life model. As here we apply rubber.

KICKSTAND

It is also known as sidestand. It is used to support the chopper while it needs to rest on the ground.

FEATURE/TOOL USED

• Sketch
• Loft
• Dome
• Extrude Boss
• Extrude Cut
• Fillet
• Split

LOFT : Addsmaterial b/w two or more profile to creates asolid feature.

DOME :- We can apply domes to faces whose centroid lies outside the face. This allows to apply domes to irregularly shaped contours and non- planar face ditection of dome -concave and convex.

EXTRUDE CUT :- Cuts a solid model by extruding a sketched profile in one or two direction. If the cut offset multiple bodies in multibody part , we can select which bodies to keep in the bodies to keep dialog box.

SPLIT :- It creates multiple bodies from a single body we can create the bodies in the existing part or in separate parts

OILTANK

The Oil tank is used to store the oil required to run the engine. It is a hollow one , the thickness of the oiltank is giveb by 3mm in our chopper model.

Feature/tool use:

• Sketch
• Boss extrude
• Combine
• Fillet
• Shell

COMBINE:- We can only combine bodies contained with in one multibody part file. we cannot combine two seperate parts, however, we can create a multibody part by using insert part to place one part into the other part file . Then we can use combine on the multibody part.

Add solid: create a single body

subtractsolid: remove over lapping material.

SHELL: The shell feature is used to define the thickness of thin and thick shell element.

PEDAL

It is external part bolted /welded with chassis . It used to keep foot while riding and it provide ease to rider.

FEATURE/TOOLS USE

• Sketch
• Extrude
• Fillet

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

LINEAR PATTERN :- It is used to create multiple instance of one or more feature that we can space uniform along one or two linear paths.

CHAIN

Chain is a type of transmission system that is used to transmit a power from the engine to the rear wheel. The sprocket is used to transmit the power to the chain the sprocket is connected with the shaft with help of a key.

FEATURE/ TOOL USED

• Sketch
• Trim
• Fillet
• Blocks
• Extrude
• Pattern
• Apperance

TRIM :- It is used to cut the extend line or curve which is beyond the sketch limit or the curve or line is no more needed.

BLOCKS :-

1. Create a sketch
2. Click make block ( tools > block > make block )
3. Select the entity you want as a block for block entities.
4. Click OK and save the first block.
5. Repeat step 2-4 for another block.
6. With the sketch in edit mode and necessary relation .
7. Finally save the part.

LOFT :- Loft surface are surface generated by multiple 3D curve or existing edge creating a smooth tangency b/w the selected curves.

SWEEP SURFACE :- Sweep surface are surface that are generated from a section curve positioned alond a path.

FILL SURFACE: The fill surface feature constructs a surface path with any number of side with in a boundary defined by existing model edge, sketches or curves including composition curve .

SURFACE TRIM :- It is use to cut away material from a surface and provide two modes standard and mutual.

SURFACE KNIT :- Surface knit is used to knit two fre edge open edge of the surface together. Also it reduces the gap b/w two edge of the surface.

ASSEMBLY OF THE CHOPPER

• Initially the chassis part is inserted in the assembly by using parts in the optin after that the part is inserted in the assembly environment or click OK to fix the chassis
• After that other parts of the chopper are inserted into the assembly and give possible mate condition.

FEATURE/TOOL USED

• Inserted parts
• Mates

MATES : Mate create geometric relation b/w the assembly components . As we add mates , we define the allowable direction of line or rotational motion of the component . we can move a component with in its degree of freedom , visualising the assembly behaviour.

DECAL

PART WITH APPLIED DECAL.

• GAS TANK TOPVIEW WITH DECAL.

• GAS TANK SIDEVIEW WITH DECAL.

• OIL TANK WITH DECAL

.

• REAR FENDER WITH DECAL

RENDERING

• Rendering is a process of creating realistic image of the photorealistic model with the environment.
• Rendering has been done in two ways in solidworks.

1. Photoview 360

2. solidworks visualize.

In the photorealistic model some of the mate condition and position are change to render realistic model. Then, the photorealistic model is rendered into realistic image with different views.

PHOTOVIEW 360 :

Photoview 360 is a visualization and rendering solution includes with solidworks. providing a highly interactive environment for viewing designs as well as for creating photorealistic rendering it can be showcase our designs.

SOLIDWORKS VISUALIZE :

Solidworks visualize provide a suit of stand alone software tool that combine industry leading rendering capabilities with visual design oriented feature and workflows, allowing easy and fast creation of visual content that communication a design vision , passion and emotion.

CONCLUSION

• The parts of the chopper are modelled.
• The parts are inserted into the assembly environment and the chopper is assembled.
• The realistic image was rendered with the use of the photoview 360 and solidworks visualize.
