Steps involved

1. Create individual parts of American chopper.
2. Assembly them with proper mates.
3. Rendering process by using photo view 360 and solidworks visualize.

METHODOLOGY

• Part Modelling
• Assembly
• Rendering

FLOW CHART 

PART MODELLING

 In part modelling, first the 2D sketch of the part is sketched using the tools in sketch tab and then the 2Dsketch is converted into a 3D part using features in the features tab.

FEATURES USED

• Boss Extrude: This feature is used to expand the object in 3D according to sketch plane.
• Extrude Cut: Extrude cut feature used to cut/remove the 3d object in linear path according to sketch.
• Fillet: Fillet is a feature used for making round internal or external edges to avoid sharp edges and make it smooth.
• Lofted Boss/Base: Lofted boss is a feature used to achieve Complex Shapes. It does this by interpolating surfaces between various cross-sections of a model. These cross-sections can be sketches, faces, or edges.
• Split: Split tool is used to split single solid part into two solid parts. It is used to project an entity onto other surfaces or curved/planar faces.
• Dome: Dome is a feature used to make dome shaped extrude including elliptical dome.
• Shell: Shell feature is used to make to hollow space in solid part by selecting outer wall of the solid part and so removes the inner parts. It is also used to reduce the specific thickness.
• Combine: Combine tool is used to make integration of two solid parts which intersect each other as same solid part.
• Chamfer: Chamfer is used to make a sharp edge or corner slightly tapered rather than being a perfect square.
• Linear Pattern: The linear parent is used to create a different number of instances required to create the pattern linearly.
• Curve Driven Pattern: Curve driven pattern is used to make any pattern which followed by the curve is sketched before.
• Circular pattern: Circular pattern is a feature used to make 3d feature into circular pattern according to number of insistences.
• Revolve boss base: Revolve feature is used to make cylindrical or circular 3D extrude along with a given reference axis as per drawn sketch.
• Revolve cut: Revolve cut is used to cut or reduce the extrude of cylindrical round surface.
• Move/copy body: This feature is used to move/copy the 3D body to one place to another place.
• Mirror: Mirror is used to mirror a feature or body by reference of the selected plane.
• Sweep: This feature is used to sweep any kind of fully defined sketch along with the path.
• Sweep cut: Sweep cut is same as sweep feature but its directly proportional to sweep which makes a cut along with the sweep path.
• Swept Surface: It is used to make a surface along with a path the curve is driven.
• Boundary Surface: Boundary surface is used to make a surface in between two finished surfaces.
• Loft Surface: Loft surface is used to make loft in between two profiles along with guide path.
• Knit surface: Knit surface is used to knit the two free edges or open edges of the surfaces together also it reduces the gap between the two edges of the surface.
• Surface Trim: Primarily used to cut away material from a surface, and provides two modes: Standard and Mutual.
•  Projection Curve: Projection curve is a 3D curve which is projected on the basis of the two different 2D curves in two different planes.
• Blocks: You can make save, edit and insert blocks from the drawing items and sketch entities that you use often such as standard notes, title blocks, label positions and so on you can attach blocks to geometry or to drawing views
• Trim entities: it is used to trim the unwanted lines or extended entities in the sketch.
• Appearances: An appearance defines visual properties of the model including colour and texture. Appearances do not affect physical properties which are defined by materials. every material is a assigned a default appearance.

ASSEMBLY

Assembly is most often referred to putting components together in an assembly line, but more specifically, it refers to creating a complete product that performs an intended function. Changes in the component are automatically reflected in the assembly i.e. The rebuild option will automatically take place or else it will ask the user to rebuild the document. 

EXPLANATION BEGIN  

Let start with step one part modelling

American chopper contain 13 parts in my design there are

1. Transmission belt
2. Front fender
3. Rear fender
4. Kick stand
5. Chain
6. Oil tank
7. Pedal
8. Front wheel
9. Fork
10. Rear wheel
11. Chassis
12. Engine
13. Gas tank

Let me explain the each parts which my part model

1. Transmission belt

It uses to transmit the power between two shafts.

Features used boss extrude and fillet.

This belt create in front plane with 3.5 mm thickness and extude to convert in 3D form and I used fillet to give realistic look for this belt.

Note :

Always remember to make your sketch full defined to get better result.

2. Front fender

It a cover plate from front wheel

Features used revolve,split and fillet.

This part ceate in front plane by using 3 point arc and revolve into particular angle and creating another two sketch to split and remove a part to get desire design and fillet it to get realistic look.

3. Rear fender

It a cover plate from rear wheel

Features used revolve, split, fillet and shell.

A sketch create in front plane by using 3 point arc and offset to get thickness of fender and revolve it particular angle and create another sketch to split and remove part then fillet and shell to get realistic look.

4. Kick stand

 It used to stand a motorcycle in slight vertical position when motorcycle in stationary 

Features used loft, dome, extrude cut, split, boss extrude and fillet.

Loft is a feature to create a stand base look by ellipse sketch and guide line. To turn a flat face into round face dome feature is used at top and bottom. To create a mate part between kick and chassis cut extrude feature is used and another sketch create in top side then boss extrude it. Finally fillet to get realistic look.

5. Chain

Its help to transmit the power between engine to rear wheel by the help of spocket.

Features used boss extrude, linear pattern, circular pattern, fillet, mirror and combine.

The whole part create by using reference sketch in front plane. To reduce a work load block should be created. By the help of reference sketch block sholud placed then fillet and pattern. repeat it then get complete model then mirror and combine to get good look of chain.

6. Oil tank

Oil tank is used in motorcycle to stored oil for better performance.

Features used boss extrude, combine, fillet and shell.

This part model create by combination of two sketch. Boss extrude and combine it to make one part then fillet and shell to get better look.

7. Pedal

Its use to rest the foot in it to give confort for rider.

Features used boss extrude, fillet, revolve, dome, chamfer and pattern.

Iike every sketch model it create by given dimensions and features like boss extrude,fillet,revolve,dome,chamfer and linear pattern.

8. Front wheel

It help vehicle to move forward and backward. It contains rim, rotor, caliper and tire.

Features used revolve extrude, boss extrude, revolve cut, cut extrude, circular pattern, mirror, combine, chamfer and fillet.

Create a bass sketch to revolve it and sketch to make a rim by boss extrude and fillet. Sketch on face to create rotor and caliper then circular pattern to make holes in rotor. Chamfer and fillet for good look. Mirror and combine for create a desire model.

9. Fork

It helps to balance and turn a wheel into desire direction. Its hold other control device for rider and shock absorber which is held by triple clamp.

Features used boss extrude, revolve extrude, revolve cut, cut extrude, project curves, swept boss, combine, mirror, chamfer and fillet.

Create a long tube by given dimension then sketch on face to create clamp and project curve for create a handle bar swept and revolve detail design and mirror it. Combine to make it single part and apply appearance for better look.

10. Rear wheel

It helps to move a bike forward by the power of engine. It contain rotor, rim, tyre, caliper, and sprocket.

Features used revolve extrude, boss extrude, revolve cut, extrude cut, circular pattern, mirror, combine, chamfer and fillet.

Create a bass sketch to revolve it and sketch to make a rim by boss extrude and fillet. Sketch on face to create rotor and caliper then circular pattern to make holes in rotor. Another sketch on face to create sprocket by boss extrude and cut extrude and circular pattern.  Chamfer and fillet for good look. Mirror and combine for create a desire model.

11. Chassis

It is a skeleton of the motorcycle because it carry every part in the vehicle. It is a base for every vehicle.

Features used revolve extrude, boss extrude, revolve cut, extrude cut, linear pattern, project curves mirror, combine, dome, chamfer and fillet.

12. Engine

Engine is a main component of the vehicle. It’s give a power to move a bike without any external force.

Features used revolve extrude, boss extrude, revolve cut, extrude cut, linear pattern, project curves mirror, combine, dome, chamfer and fillet.

It creates by the help of blueprint. By the reference we have then we can model and project it desired shape.

13. Gas tank

It’s carry a fuel for the engine. Based on design fuel carry level is varies for different motorcycles.

Features used swept surface, loft surface, boundary surface, project curve, knit surface, combine, shell, mirror and fillet.

It creates by the help of blueprint. By the reference we have then we can model and project it desired shape.

 

Assembly

By opening every part model it bring single location to assemble a part easier. By using different type of mate operation such as concentric, coincident, parallel etc. mate will be made in that we face some overlapping issues but it resolve in assemble level itself. After resolve everything assemble will be done at our desires.

RENDERING

Rendering is a process to bring our model into realistic ways with environment.

Photo view 360

It will be done in solidwoks 2018 itself. It help as to add light, camera, decal and scene. 

                                                                               

Conclusion

• The part model its design as per given dimensions.
• Assembly made with proper mate and resolve overlapping issues.
• Rendering process done on photo view 360.
