FEATURES DESCRIPTION:
SKETCH:
- Sketch is a two-dimensional representation of the model with respect to the plane / view from the outside of the model. There are distinct sketch possibilities available
in solid works to create a sketch. These are referred to in solid works as Entities. The following are the parts available in Line, Arc, Spline, Circles, Rectangular solid works.
OFFSET:
- A specified distance includes one or more sketch entities, selected model edges, or model faces. For example, you may offset sketch entities such as
splines or arcs, model edge sets, loops, and so on. Finite lines, circles, and splines may be offset.
EXTRUDE BOSS/BASS:
- Extrude is a form of function available for transforming a 2D sketch into a 3D model in solid works.
LOFTED BOSS/BASS:
FILLET:
-
A rounded internal or external face on the component is created by Fillet / Round. All the edges of a face, selected sets of faces, selected edges, or edge loops can be filled.
CHAMFER:
SPLIT:
-
The Split tool is used to project an object onto other surfaces or curved / planar faces (sketch, solid, surface, face, plane, or surface spline). You're also capable of splitting faces into
different bodies with one order.
DOME:
-
Choose one or two planar or non-planar faces. For faces whose centroid lies outside the face, you can apply domes. This helps you to add domes to contours which are irregularly shape.
EXTRUDE CUT:
-
Another great feature, Extrude cut, helps remove materials from the 3D model.It is just the opposite of the boss / base extrude feature, since while extruding, it cuts a sketch profile.
You can cut in both directions and use them exclusively to create holes, channels, slots, etc.
REVOLVE:
-
Create a sketch containing one or more profiles and a centerline, line, or edge that can be used as the axis around which the feature revolves. Tap on one of
the following revolving tools.
DYNAMIC MIRROR:
COMBINE:
TRIM ENTITIES:
-
Based on the entities you choose to trim or expand, pick the trim form. With 2D sketches and 2D sketches on 3D planes, all trim forms are available. Any of the following trim
options can be used: Power trim.
SHELL:
LINEAR PATTERN:
CIRCULAR PATTERN:
SURFACE MODELING:
-
Surface modelling allows you the opportunity to produce a visual depiction of the exterior of an object and its contours. It is, in other words, a surface. Parts such as the seat and
the classic 350 fuel tank are surface-modeled.
APPEARANCES:
-
An appearance, including colors and textures, determines the visual properties of a model. Physical properties, which are determined by materials, are not affected by appearances.
A default appearance that emulates the look of the material is given to any material.
DESCRIPTION OF THE PARTS AND FEATURES USED:
- Transmission Belt:
* The transmission belt is used to transfer power from the output shaft of the engine to the input shaft of the gear box. Polyster material with the layers or kevlar and sandwich with
metallic wires is usually made. It's a combination of different components that gives it strength to transfer the full horse power produced from the motor to the gear box.
* The transmission belt profile is produced according to the dimensions of the front plane, with a thickness of 3.5 mm provided to the belt. The belt is extruded after
the sketch has been finished. The square edges of the fillet are given. The transmission belt is made of matte rubber.

2. Kick stand:
Kick stand is a supportive framework provided to a bicycle or motorcycle to help it stand while stationary in a vertical position.
FEATURES USED:
- Sketch
- Loft
- Dome
- Extrude Boss
- Extrude cut
- Fillet
- Split
- Appearances
To build the kick stand, loft features are mostly used. On the right plane, one at the top end and one at the bottom end of the kick stand, two ellipses are created.
On the front plane, a path is sketched that connects the centre points of the two ellipses generated before using the pierce relation between the centre of the ellipses and the path.
The body of the kick stand is built using the loft. To build the rounded end of the kick stan, the elliptical dome feature is used.At the top end of the stand, a slot with an extruded boss is
formed by connecting it to the chassis. The sharp edges of the stand are finally supplied with fillets. The appearance of the Chrome plate will be added to the kick stand.
For the portion of an automobile, motorcycle or other vehicle body that frames a wheel well (the fender underside), Fender is the American English term. Its primary purpose is to
prevent the spinning tyre from tossing sand, dirt, gravel, chemicals, and other surface sprays into the air.
FEATURES USED:
- Sketch
- Offset Entities
- Trim entities
- Revolve
- Dynamic mirror
- Split
- Appearances
A sketch is made using a three-point arc in the front plane and offset it to match the thickness of the fender. Establish an axis at the source. The requested front fender is created
using revolve boss. In the top plane and the right plane, 2 separate sketches are created to cut the front fender to the form necessary. On the sharp edges of the fender, fillets are
formed. The perfect look is added to the fender.
4.REAR FENDER
For the part of an automobile , motorcycle, or other vehicle body that frames a wheel well (the fender underside), Fender is the American English term. Its primary function is to keep
the rotating tyre from throwing sand, mud, gravel, liquids, and other road spray into the air.

spider web spokes and the rim are merged.

10.FRONT FORK
For the front suspension, most bikes today use telescopic forks. The forks with internal coil springs can more readily be understood as essentially large hydraulic shock absorbers.
They cause the front wheel to adapt to road imperfections while isolating the remainder of the motorcycle from the motion. To provide comfort to the rider, it removes the bums.

Sweep:
We can create a form with the Sweep function by moving a 2D sketch profile along a 2D or 3D sketch path.
11.CHASSIS
Its skeleton shapes the chassis or assembly. All of a motorcycle's parts, such as the suspension, wheels, fuel tank, seats, handlebars, etc., are related to this simple structure
that gives a motorcycle its power and capacity to handle well.

13.GAS TANK
A safe reservoir for flammable fluids is a gas tank (or petrol tank). The term is usually applied to part of an engine structure in which the fuel is contained and pushed (fuel pump) or
released (pressurised gas) into an engine, but any holding tank for fuel may be called so.
FEATURES USED:
- Sketch

SURFACE TRIM:
EXTEND SURFACE:
-
To expand the surface that is already made, Extend Surface is used. On the expanded board, there are various choices available. We can expand the surface to the same surface, or
we can extend the tangent of the surface to the surface.

Assembly of the American Chopper
1. In Solid Works, all the designed parts are taken into the assembly section and the whole assembly of the American Chopper is produced using distinct mating
characteristics such as concentric, coincident, parallel, etc. The decals are added to the chopper after assembly.
2. I used multiple possibilities for limitations, such as Coinsident, Concentric, Tangents, and Distance, when making Assembly.
3. In addition, by considering the geometry simulation features (plane surfaces and vertices), I added the above-mentioned limitations
FEATURES USED:
Mates:
Mates build geometric relations between components of the assembly. We define the permissible paths of linear or rotational motion of the components as we add matches.
Inside their levels of independence, we may transfer a part, visualising the actions of the assembly.
RENDERIND
-
Rendering is the method of making with the reality accurate representations of the Photorealistic model.
-
In SolidWorks, rendering has been accomplished in two respects. The two manners are as follows,
-
360 Photoview
-
Visualize Solidworks
-
Any of the mate conditions and locations are
altered in the photorealistic model to make realistic ones.
Then, from various perspectives, the photorealistic
model is turned into functional pictures.




Conclusion :
-
The components of the chopper are sketched and modelled in SolidWorks.
-
The components are placed into the setting of the assembly and assembled by applying the mates' chopper.
-
Using 'Photoview 360 & SolidWorks Visualize', the realistic image was rendered.
