Photo Realistic Rendering

Design, Assembly and Photo Realistic Rendering of American Chopper by Using SolidWorks 2020 3D CAD Software.

1-Objective:

• The main objective of this Project work is to Design and Assemble the American chopper, by using minimum Sketch tools and Features of SolidWorks 3D CAD Software.
• And to learn how to use features with great precession.
• To use the photo view 360 in SolidWorks and Rendering tools.

2-Introduction to SolidWorks:

SolidWorks is a solid modeler, and utilizes a parametric feature-based approach which was initially developed by PTC (Creo/Pro-Engineer) to create models and assemblies. The software is written on Parasolid-kernel.

3-Design Methodology:

Fig1: Design Methodology of Assembly and Photo Rendering

The parts, which are shown above in flow chart are designed by using the latest version of SolidWorks Software. After designing Parts of AMERICAN CHOPPER, they got assembled by using Assemble parts option.

3.1-Assembly:

Assemble Parts option is shown directly when we start creating the new document.

Fig 2: Visibility of Assembly Option

The parts are call in to the assembly by simply clicking the insert component option, which is available in the menu. The part are inverted individually or we can call it bulk, but inserting individual is more preferrable than the bulk.

3.2-Mate:

The mate option is used mainly to set the parts of the American Chopper in their required location. By using mate option, we give tangency, distance, coincide, or even give angle to the mating parts. We can even mate planes by using the mate option.

Fig 2.1: Visibility of Mate Option

Mate option plays very important role during assembling the parts. The options are shown in the figure are used in assembling the American Chopper.

3.3-Photo Rendering:

Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure.

Rendered images has a nice graphics compared with normal assembly

Fig 2.2: Normal and Rendered Image of The Chopper

Above shown images are rendered and normal images. The right image of chopper has applied a nice graphics.

Rendering of assembly should be done by going in to photo view 360 and rendering tools. Photo view 360 is located in SolidWorks add inn.

4-Description:

chassis, tank, kickstand, Engine, Front fender, rare fender, Front wheel, rare wheel, front forks gas tank are the above parts which are made by using SolidWorks 2020.

Sketch Tools Used:

Line:

It helps to draw a line of the graphics sketch area. In side drag menu centerline option also available. This tool helps to create center line for the 2d drawing. The centerline representation follows the engineering graphics drawing tools. The new version of SolidWorks contains Midline which helps to make lines on both sides.

Rectangle:

It helps to create rectangle box in the sketch area. In the side down drag menu, you can see the different rectangle drawing methods such as Corner rectangle, Center Rectangle, 3 Point Corner Rectangle, 3 Point Center Rectangle and Parallelogram.

Arc:

It enables to draw arc. It contains 3 arc drawing methods and they are Center point Arc, Tangent Arc and 3 Point Arc.

Circle:

It helps to draw a circle. IT contains two circle drawing method such as, center point circle and Perimeter circle.

Spline:

Splines are used in mechanical for mating the rotating parts. It is two types internal and external splines. This tool helps to draw highly smooth curves or lines of the sketch.

Straight Slot:

It helps to draw a straight slot in 3D object. It also contains arc slot tool which create an arc slot. It have two types of slot drawing methods such as centerline method, center point, 3 Point arc and Center point arc method.

Ellipse:

This tool helps to draw Ellipse on the drawing interface. You can also draw partial ellipse and parabola form the down drag menu.

Smart Dimension:

The smart dimension is one of the useful tools to create sketches as mentioned in your drawing. You don’t need to care about the dimension of the sketch profile while drawing. It will adjust using Smart Dimension tool in later action.

Plane:

It helps to insert a plane in a 3D sketch.

Sketch Fillet:

If you want to adjust the corners or make round at the corners of sketch, use the Sketch fillet tool. You can enter the fillet parameters through the property manager.

Convert Entities:

It helps to convert selected model edges or sketch entities into sketch segments.

Offset Entities:

It enables to insert the SolidWorks sketch entities offset to face or edge or curves or specified distance from it.

Features used:

Extrude Boss/Bass:

The Extrude Boss/base is one of the most frequently used tools in SolidWorks, which enables to convert a 2D sketch into 3D model. It helps to add material to your sketch files. It is represented by icon When you click on the Extrude button, the property manager opens where we can control everything about extrude.

Revolve Boss/Base:

The revolve feature enables to add materials to your 2D sketch by revolving a long as centerline or axis. The revolve boss/base is actually rotate the sketch along an axis. It helps to create parts shows the symmetry like cylinder, sphere, pulleys etc.

Swept Boss/Base:

It is sweep feature which sweeps a closed profile through a open or closed path for making solid object. This feature helps to make solid part by guiding through a definite path.

Loft Boss/Base:

It helps to create solid model between two profiles in a certain distance. It needs two or more profiles to add materials into it.

Extrude Cut:

Unlike the extrude boss, the Extrude cut removes the material from 3Dmodel by using a closed sketch (Circle or rectangle etc.). You can do the cut in one or two directions the using the property menu.

Revolved Cut:

Using the Revolved Cut, you can remove the material by revolving a closed sketch around an axis.

5-Parts of American Chopper Assembly:

5.1-Chassis:

Fig 3: Chassis

Chassis are generally used to mount the parts. it is also known as supporting frame of the structure. The total structure of the body depends on the chassis. In this several sketch tools and features are used to build the chassis. The sketch tools which are explained above are used to prepare chassis.

5.2-Engine:

Fig 3.1: Engine of American Chopper

Engine is a heart of a vehicle. Working of vehicle is totally depends in the engine. Engine converts the chemical form of energy in to the mechanical form.

5.3-Front Fork:

Fig3.2: Front Fork of American Chopper

Front fork is used to place the front wheel, and other parts which are used in braking system, not only that it is used to handle the vehicle. Line and other sketch tools are used to modal the front forks. Extrude and another features which are explained above used to construct the front forks.

5.4-Gas Tank:

Fig 3.3: gas tank of American Chopper

Spline and composite curves are used to build the gas tank of American chopper.in this first surface modeling tools like surface loft, split curve and other tools are used. later it is modified in to the part. Siena color is used as appearance.

5.5-Tank:

Fig 3.4: Tank of American Chopper

For the tank lines, arc, fillet is used in sketch. Feature tools like extrude, combine, split options are used to make part.

5.6-Chain:

Fig 3.5: chain of American Chopper

Chain is used to transfer the motion, which lead the vehicle to move forward. In this first time we came across the blocks. Where blocks are stored and use them externally. Splines and arc are used to made the path of the chain. Arrange the blocks on the path and extrude it by using from vertex option.

5.7-Front and Rare Wheels:

Fig 3.6: Front and Rare Wheel of American Chopper

Wheels are used to move the vehicle. circle is the major sketch tool which is used to construct the wheel. Revolve and revolve cut is used to construct the outer part, and to cut the spider weds. Convert entities is used to project the sketch on other plane. Which plays a crucial role during designing the wheel and spiderwebs.

5.8-Front and The Rare Fenders:

Fig 3.7: Front and Rare Fenders of American Chopper

The above shown are front and rare fenders are used to protect the wheels, form mud and stones, not only that, these fenders are designed in such a way that it changes the looks of the vehicle and the decals are also added to look better. Revolve and spline are used in the construction of the both fenders.

5.-Pedal, Kickstand and transmission belt:
