Procedure
- This model is done by creating mirror features by sketching one half
- Front Axle frame is designed by applying to extrude revolves and cut solid bodies.
- The handlebar frame is designed with a projected curve feature to sketch. And sweep based on the circle and the projected curve
- The headlight model is designed and dome, chamfer features applied.
- Finally, the model is mirrored and the necessary appearance is given to different parts. Visual Propagation is checked to apply the appearances on both sides.
- Luminous intensity is applied to the headlight model for effective display when doing rendering.
Chassis
It is mainly designed to keep all the parts in the chopper this is mainly done with the help of sweep, project curve and reference plane

- Mirror is used for mirroring the sweep through a plane
- Extrude ,cut extrude are used at the end of the sweep and the mirror
- Sweep and extrude are used to design it up to the back wheel
- Then a sweep is created to keep the gas tank
- A revolve is created at the end of the sweep to fix the front fork

Gas Tank
- The Gas Tank is approached using Surface Modelling Features and converted to a rigid solid body after enclosing as a closed surface model.
- The Gas tank provides the Seating grip for the Rider and looks stunning with different themes and sketches with different choppers.
- The main purpose is to store the Fuel and hence the solid body is shelled to the appropriate thickness.
Features involved
- Surface Sweep
- Surface Trim
- Surface Loft
- Boundary Surface
- Surface Knit
- Sweep cut
- Fillet
- Mirror
- Shell
The Decals are added to the tank using Photo view 360 and appearances are given as sienna car pain for the main body.
Assembly procedure
- At first chassis is taken from the document to the assembly and fixed
- Then engine is taken from the document coincident mate and distance mate are used to fix the engine to the chassis
- Pedal is fixed with the assembly by using concentric mate and coincident mate
- Then the pedal is mirrored to get the pedal on the other side
- The transmission belt is fixed between the two gear drives and ensured that the tooth meshes properly.
- Oil Tank is placed above the Engine Casing.
- Rear Wheel is attached to the End frame of the Chassis and Rear Fender is placed using appropriate concentric mates.
- The chain is Inserted between the rear wheel sprocket and Engine Sprocket.
- The Gas Tank is placed over the Top Frame.
- The Front Axle is attached to the front shaft of the chassis.
- Finally, the Front Wheel and Front fender are attached to the axle
- The Axle, Front Wheel, and Fender are given an angular mate to move on both sides.
- The Kickstand, Front Wheel, and Rear Wheel are grounded to the Plane to create a realistic model view.
- Design and Assembly of American Chopper using Solid works and Photorealistic rendering
