Photo Realistic Rendering
TITLE - MODELLING AND RENDERING OF AMERICAN CHOPPER USING SOLIDWORKS.
OBJECTIVE:-
To create a 3d model of American Chopper using Solidworks 2020.
Create model of different sub-assemblies of chopper using solidworks.
Assemble the model parts to get final model.
Rendering final model to get Photorealistic model using Solidworks Photoview 360.
INTRODUCTION:-
To design any object we have to start with modelling 2d and 3d images. 2d modelling is a process of representing different view of physical body in space. 3d moselling is a process of representing a physical body using collection of points in 3d space. Part modelling consists of both processes while designing any object. In part modelling we can create a part from a conceptual sketch through solid feature based modelling, as well as build and modify parts through direct and intuitive graphical manipulation. This project consists of sketching, featuring and part modelling different parts of American chopper with the help of Solidworks 2020.
DESIGN METHODOLOGY:-
DESCRIPTION:-
Part creation process start from drawing fully defined 2d sketches. These sketches are the references to multiple features by which 3d part created.
Sketch - It consists of various options for creating different entities:-
Line, Circle, Polygon, Spline, Offset, Fillet, Convert entities, Trim entities.
Different ways to use above options:-
1) Features and Surfaces - These tabs consist of multiple options which can help to create different shape solid body and surfaces.
2) Appearance - In this feature, we can apply material or visual appearance to part or model. These appearances help us while rendering to achieve real world image.
AMERICAN CHOPPER:- It consists of 13 parts/ sub- assemblies as per below:-
a) Transmission belt - It is used to transmit power engine to gearbox.
Features used to create transmission belt:-
1) Extrude- This feature is used to convert 2d sketch into 3d object.
2) Fillet - This feature is used to convert external and internal edges into rounded shape.
3) Offset entities - It is used to create same entities on some distance.
Procedure:-
1) Draw the fully defined sketch of require dimension on front plane using line and arc option. Then offset the sketch on some distance to create thickness of belt.
2) Then extrude command is used to convert 2d sketch into 3d.
3) Fillet is applied as per requirement to sharp edges.
4) Model is fully defined and should be saved.
b) KICKSTAND - It is used to support chopper when not in use and pivoted to chasis in such way that it can be move down the frame.
Features Used:-
1) Extrude boss- This feature is used to convert 2d sketch into 3d object.
2) Fillet
3) Loft- It determines the profiles used to create a loft. Select sketch profiles, faces or edges to connect. Lofts are created based on the order of profile selection.
4) Dome- This is used to apply dome shape to faces. This allows you to apply domes to irregularly shaped contours.
5) Split- This feature is use to split the solid bodies, surfaces and allow us to remove unnecessary portion.
6) Extrude cut- It help to remove the material from solid bodies.
c) FRONT FENDER - It is mounted on front wheel and below the front fork. It prevents mud particle being thrown into the air by rotating tyres.
Features used:-
1) Revove- Any profile can be revolved about an axis, centre line or edges and obtain solid bodies from 0 degrees to 360 deg.
2) Dynamic mirror- In this you can mirror any sketch or entities about pre-selected sketch or entity.
3) Offset entities.
d) REAR FENDER:- The use of rear fender is same as front fender. It is mounted on chasis above the rear wheel.

2) Revolve.
3) Extrude boss.
4) Fillet.
5) Dome.

ASSEMBLY OF AMERICAN CHOPPER:-
To start assembly, Load new assembly file.
While assembly, we need to insert each part step by step followed by mating relations to each other.
Features used for assembly:-
1) Insert part.
2) Mates.
3) Mirror.
Mates - It is use to provide relation between part as per their working principle. We have to define the mates as per present condition and whatever look we require.
Relations used in mates:-
Coincident, Parallel, Concentric, Angle, Tangent, Width Mate.
PHOTO REALISTIC RENDERING:-
Rendering is the process of creating realistic image model in real world environment.
Rendering can be done by 2 ways - Photoview 360 and Solidworks Visualize.
Following are the rendered images in Photoview 360:-
Rendered images in Solidworks Visualize:-
CONCLUSION:-
1) Understanding of user interface of solidworks.
2) Part modelling of American chopper using solid modelling tools in solidworks.
3) Understanding of features and flexibility of modelling in solidworks.
4) Part is assembled together to get complete assembly in solidworks.
5) The realistic image generates in photoview 360 and solidworks visualize.
