DESIGNED AMERICAN CHOPPER,ASSEMBLY, AND RENDERING
INTRODUCTION
This report cover the designing part of american chopper,a complelete large assembly and rendering. Here we are going to design the variouspart of the american chopper.
OBJECTIVE
Design is the pratice creating things. It is a diverse practice that draw from engineering, here we will understand how tool behave when we use it and we will foucs on how many ways we can draw a similar diagram, to design american chopper 2 to 3 day to complete the design.
PARTS AND EXPAINATION
1. TRANSMISSION BELT
A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel.In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts). As a source of motion, a conveyor belt is one application where the belt is adapted to carry a load continuously between two points. The belt drive can also be used to change the speed of rotation, either up or down, by using different sized pulleys.
To design the belt we have use feature like 2d sketcher, extrude, fillet.
Process
Step 1; Select the front plane to sketch, draw a line horizontal with origin and 3 point arc ,and dimension it to make fully defined.
Step 2; Make a offset of 3.50 of last sketch inward direction.
Step 3; Create extrude feature by selecting sketch , and extrude it by giving dimension.
Step 4; Use fillet all side of the corner to do smooth finishing.
Step 5 ; Give the apperance to the transmission blet of rubber mate to look realistic.
2. KICKSTAND
A kickstand is a device on a bicycle or motorcycle that allows the bike to be kept upright without leaning against another object or the aid of a person. A kickstand is usually a piece of metal that flips down from the frame and makes contact with the ground.
To design the kickstand we have used 2D sektcher , extrude , extrude cut , dome , filllet.
process
step 1; Front plane>> Draw a ellipse which is horizontal to origin and make a sketch fully defined by giving dimension with origin. Then select right plane and then make a spline selecting origin and dimesion it. Activate the spline handle as required dimension.Next create new plane at the end of the spline. then draw new ellipse in new plane and make pierce relation to end of the spline which will help us to create loft base feature.
step 2; Apply elliptical dome feature to end of the spline. use fillet in kickstand for smoothness.
step 3; Give appearance, selecting the chrome plate finish to look realistic.
RENDER IMAGE
3. FRONT FENDER
TO DESIGN THE FRONT FENDER WE HAVE USE 2D SKETHER , REVOLVE, SURFACE TRIM, THICKEN, EXTRUDE CUT, FILLET.
Process
Step 1; Front plane>> Sketch 3 point arc above the origin which will vertical to origin. use offest feature at arc in inward ,then extend the entities next close the arc by line entities.
step 2; Select the sketch and use revolve feature through construction line by specifing the angle in both the direction.Select the body cut out the remaining part
step 3; Use fillet at edge of the front fender for smoothness.Apply the appearance by selecting siena color.
4. REAR FENDER
To design the rear fender we have used feature like 2d sketch, extrude cut , thicken, shell,revolved, surfaced surface trim, fillet.
Process
Step 1; Front plane>> Sketch 3 point arc above the origin which will vertical to origin. use offest feature at arc in inward ,then extend the entities next close the arc by line entities.
step 2; select the sketch and use revolve feature through construction line by specifing the angle in both the direction. select the body cut out the remaining part
step 3; use fillet at edge of the front fender for smoothness. apply the appearance by selecting siena color.
5. OIL TANK
Any tank for containing or storing oil such as a very large oil storage container at a refinery or a large oil storage area on an oil tanker or a smaller container for the storage of heating oil at a property.
To design the oil tank we have use feature like 2d sketch, surface extrude,fillet, surfacetrim and surface knit,shell, extrude.
process
Step 1 Select the top plane and draw 2d sketch of oil tank using Line ,3 point arc, make a relation to each other. To make fully defined. Then extrude the part.
step 2 Select th fornt plane and draw 2d sketch by using spline , line ,make the sketch fully defined. And then extrude it by mid plane by through all option, and combined two seperated bodies.
step 3 Use fillet in all the corner of the tank for the smooth edge. give the seina color.
CHAIN
6. CHAIN
A bicycle chain is a roller chain that transfers power from the pedals to the drive-wheel of a bicycle, thus propelling it. Most bicycle chains are made from plain carbon or alloy steel, but some are nickel-plated to prevent rust, or simply for aesthetics.
To draw the chain we use feature like extrue, mirror, fillet, curve drive pattern.
process
step 1; Select the front plane CHAIN and create a sketch by clicking on the 2D Sketch icon. The origin should be in the middle of the biggest circle. draw path of the chain using line and arc. use insert block feature to add two add another 2d sketch diagram. And make relation with sketch spline ,concentric with another part. use curve driven pattern . Extrude the pins and plates. use fillet to look smooth.
step 2; select next arc again insert the block 1 and 2 make block 1 coincident with arc and concentric. after doing all the path of chain separate the pin and plate in new folder. Use mirror option to mirror all
7.PEDAL
Used feature extrude, revolve, dome, linear pattern, fillet chamfer.
process
step 1 Draw the sketch on front plane, line with origin 5 lines and 2 splines. and give all dimension with orign to make fully defined. Then extrude it use fillet in all edge.Select the front surface of Extrude1 and create a sketch by clicking on the 2D Sketch icon make a two circle and extrude it. use dome circular feature
step 2 Use the linear pattern across the boss extuded. Use distance-distance chamfer option.
8. FRONT WHEEL AND REAR WHEEL
FEATURE USED, EXTRUDED CUT, BOSS EXTRUDE , REVOLVE, REVOLVE CUT, FILLET, CHAMFER, LINEAR PATTERN, MIRROR, CIRCILAR PATTERN, COMBINE.

step 1 select the front plane and create a sektch of upper part of the wheel by line draw a constuction line throught origin to upward and make the sketch fully defined.
step 2; turn on the temporary axis to revolve it.
step 3; select the right plane sketch on it by draw a constuction line from origin to upward and draw the next construction line of angle direction ,use the spline command. mirror the all three entities across the vertical construction line . extrude the feature.
step 4; to draw spider webbed degine, offset all the 3 entities of other side. use the cut extrude feature to remove material.
step 5; draw the 3 circle from the origin concentric to each other, convert the entities .and offset in ward direction to get intersection point , trim rest of the unwanted entities. make 3 point arc with intesection point in all the 3 circle of intersection point make the sketch fully dimension. and then extrude it.
step 6; select the front plane we need to removed large amount of area so draw a spline from origin to upward. cut the extrude part.
step 7 use the circular pattern spider webbed degine and combined all the solid body .
step 8 select the front plane draw a circle and extrude it. slect the extrude circle and sketch on it, draw new small circle ,use linear pattern give the 4 instance, cut extrude part .
step 9 convert the intersection curve and draw arc and line . then revolve it. create profile on tire and cut extrude and use fillet part. give the apperance

step6; Select the front plane to create the cylindrical part of the engine. Draw a line from origin again draw a line which will be colliner to line. Generate the new plane by selecting the line and end point of the line . sketch in new plane draw a rectangle and extrude it upward. use fillet as well. create angle rectangle to new plane and use cut extrude part.
step 7;.Draw a curve. sketch 2d diagram in two different plane by ensuring the end point should be same . use the feature like convert entities. construction line ,spline. after getting projected curve , draw two concentric circle make sure the using pierce relation to it then sweep it.
