Introduction

Solid work- Solid work is a software which is developed by dassault systemes and used for CAD (computer-aided design) and CAE (computer-aided engineering).
Aston martin- Aston martin is a British public limited company, founded in 1913 and known for manufacturing luxury sport cars and grand tourers.
Aston martin one- 77 car- It is a cars model manufactured by Aston Martin Company and designed by Marek Reichmann.

Some interesting facts about this car is, this model manufactured in 2009-2012 and only 77 model’s are available in the world, that’s why this model name is one-77.

Command used

Sketch command

2D sketch- 2D sketch is a command for making sketches to required solid bodies. We have to choose any one plane for start sketch with front, top or right plane
3Dsketch- 3D sketch is a command for making sketches without any plane required. The sketch will be 3 dimensional rather than 2 dimensional.
Line- For making line this command used. And have two another types of line constructing line and mid-point line.
Circle- For making circle this command use. And have another types which is perimeter circle which need three points to make circle.
Spline- It is used for making desired curve basically a cure which is very complex to make. Therefore this command comes very helpful and also have 3 another types- style spline, spline on surface, and equation driven curve.
Rectangle- Rectangle tool is used for making rectangle and this tool have four types- centre rectangle, 3 point corner rectangle, 3 point centre rectangle, and parallelogram.
Convert entities- Converts selected model edges or sketch entities into sketch segment.
Offset entities- Add sketch entities by offsetting face edges, curve, or sketch entities a specified distance.
Trim entities- Trim or extends a sketch entity to be coincident to another or deletes a sketch entities.
Mirror entities- Mirror selected entities about a centreline or place reference.
Circular sketch pattern- Add a circular pattern of sketch entities.
Move entities- Move a sketch one place to another place.
Smart dimension- Create a dimension for one or more selected entities.
Sketch picture- To insert the sketch picture as a blue print setup.
Display/delete relations- Display and delete geometrical relation.

Features command

Surface loft- Creates a lofted surface between two or more profile.
Boundary surface- Creates a boundary surface between profiles in two direction.
Fillet/round- Creates a rounded internal or external face along one or more edges in solid or surface feature.
Chamfer- Creates a bevel feature along an edge, chain of tangent edges, or a vertex.
Fill surface- Creates a surface patch within a boundary defined by existing model edge, sketches or curves.
Surface offset- Creates offset surfaces using one or more contiguous faces.
Ruled surface- Inserts ruled surfaces from edges.
Surface extend- Extend the edges, multiple edges or the face on a surface based on end condition and extension type.
Surface trim- Trims a surface where one surface intersects with another surface, a plane or a sketch.
Knit surface- Combines two or more adjacent, non-intersection surfaces together.
Delete face- Deletes faces form solid bodies to creates, or deletes faces from a surface bodies.

Curve command

Projected curve- Creates a 3D sketch using two 2D sketches.
Split line- Creates curves on the solid bodies using sketches.

Methodology

Surface modelling

Blue print setup(BP setup)- Blue prints are the reproduction of the original drawing which was firstly made by an architect or a draughts man or a designer, and blue prints are used to make multiple copies or zerox of that kind of object.

Here I used blueprints to give my Aston martin car a perfection model as a design.

Feature used for setup

Sketch picture

Methodology used-

Firstly Inserts the blue prints
Then Sets the dimensions of BP in centimetres
Then Untick enable scale tool & lock aspect ratio
After that Seted the transparency

Modelling of roof, sides, back rails- These all are the surfaces of the car and together these makes car’s body, where roof are used to weather protection and sometime used for luggage career and sides of the car are used to provide gates in the car whereas back rails are the back side of the car which depends on the car design some time it used to make extra extra space to carry luggage.

Feature used

Sketch tools
Boundary surface
Fill surface
Offset surface
Ruled surface
Knit surface
Trim surface
Cut with surface
Smart dimension
Fillet
Projected curve
Etc.

Methodology used-

Started one side sketches with the help of side and top BP and make fully defined with proper dimensions and relations for neglecting errors in surface generation
Generated curves with the help of fully defined sketches
After that with the help of curves generate needed surfaces
Trims the extra surfaces where needed to be trim

Roof

Side

Back rails

Parts modelling

Modelling of windshield, windows, rear lights, front light- These are the fixed parts of the car where wind shields protect with air coming when car in speed and window are used for internal environment of the car for comfort whereas rear light and front lights are mainly used to travel in night for escaping with accidents.

Feature used

Insert into new part
Sketch tools
Boundary surface
Fillet
Combine
Delete/keep body
Split
Linear pattern
Cut with surface
Extend surface
Trim surface
Thicken
Projected
Split line
Smart dimension
Etc.

Methodology used-

After creation of roofs, sides and back rails surface the windshield, window, rear lights and front light parts are creates in different file with insert into new parts command, these are the type of fixed parts
After that with the help of BP’s and proper dimensions starts sketches
And with sketches generated curves
And with the help of curves generated surfaces
And trims the extra surfaces where needed to be trim
In the front lights the thin feature command used to give extra thin profile

Front lights

Windshield

Windows

Rear lights

Modelling of rims, wheels, disc brake, clipper- These parts are floating parts of the car and these parts make complete wheel to run on the road where rims are used to support the cars load and wheels runs on the road with direct contact with road whereas disc brake and clippers are used to stop the car without any jerk with accurate timing.

Feature used

Boss extrude
Revolved boss
Sweep boss
Lofted boss
Cut extrude
Draft
Mirror
Sketch tool
Circular pattern
Combine
Fillet
Delete/keep body
Etc.

Methodology used-

For these parts of the car started a new sketches and insert blue prints of wheel
After that with the help of BP started sketch with proper dimensions and relations to make fully define the sketches
And with the help of sketches created the solid profile of rims, wheels, disk brake and clipper
Disk brake are created with ideal dimensions not with the help of BP
The front wheel and rear wheel dimensions are different that’s why front and rear wheels are made separately
Appearance are used to give for material and actual looks

Brake disc

Clipper

Rim

Tyre

Emblem creation- Emblem is a visible object or representation symbolizes or a concept like a moral truth or a person or an allegory.

Here the emblem represents the Aston martin company.

Feature used

blue prints
sketch tools
boss extrude
cut extrude
combine
smart dimension
delete/keep body
Etc.

Methodology used-

For making emblem started a new sketch and insert blue prints of emblem
With the help of BP started sketches an make them fully defined with dimensions and relations
After that created a solid profile of emblem
And used appearance for proper look of emblem

Aston martin emblem

Creation of wheel assembly- The wheel assembly is that’s parts which complete the wheels and these parts are rim, clippers, brake disc, wheel tyre etc.

Feature used

Mates
Browse parts
Etc.

Methodology used-

Starts a new assembly and then inserts the all parts to make complete wheel, and that are rims, wheel, disc brake, clipper
Make mates relation with all parts one by one
Firstly brake disk and clipper then wheel and rim
Then mates relation between assembly of clipper and assembly of rim to make complete wheels of front wheel and rear wheel

Assembled wheel

Modelling of back reflector- Back reflector are for comfort driving to see the back said environment of the care to make sure for driver to change their direction according to needs.

Feature used

Sketch tools
Projected curve
Thicken
Knit
Fillet
Boundary surface
Filled surface
Etc.

Methodology used-

After completing the sides, roof and back rail start sketch to modelling of back reflector
With the help of blue prints of car completed fully defined sketch with the help of front, side and top BP one by one
The generated curves with sketches and the surface modelling started
The back reflector firstly made with some certain distance and then after connected with the side of the car
Thin feature used for making mirror of the back reflector and sometime trim and, cut with surface command used

Back reflector

Parts assembling

Creating constrains with surface modelling & parts modelling- After making all floating and fixed parts and car surfaces now it’s time to final assembly of all parts with car to look like a final luxury Aston martin one-77 car.
