Aston Martin ONE-77 Challenge-11 (Project)

Surface Modeling of Aston Martion 0ne-77

Objective

This project aligns its scope with developing a complete surface model of Aston Martin One-77 in Solidworks design tool.

Introduction

One-77 is a 2-door sports car built by Aston Martin, a British automobile giant. The concept was revealed by the automaker in 2008 Paris Autoshow. Yet it was fully revealed at 2009 Geneva auto show and went on sale from 2011. Only 77 of these were on sale and so the name One-77.

This project involves designing the complete surface modelling of Aston Martin one-77 in Solidworks.

Design approach

Features description

Boss/Base features

The features under this header deals with creation of solid bodies.

Extrude

This feature lets us extrude a sketch to a specified distance or to any constrained dimension.

Revolve

This feature revolves a given sketch about a specified axis.

Sweep

This feature lets us develop swept bodies with sketches and guidelines prescribed.

Solid Cut features

The features described under this header deals with removing parts of solid bodies.

Features like Extrude, revolve and sweep are also used to remove solid part bodies. The functionalities of these features remain the same like we saw previously expect for these are used to remove parts of bodies in this case.

With surface

This feature can be used to remove parts by using other parts or bodies as trim tools

Manipulation tools

The features under this header throws light on solid/surface manipulation tools in solidworks

Fillet/ round

This feature allows us to smoothen out the selected edges of a part

Chamfer

This feature is very similar to fillets but adds a chamfer to the edge instead of leaving a rounded edge

Draft

This function is used to generate faces that are tapered to some degree from the horizontal or vertical planes

Shell

This function can be used to scoop out the inner volume of a body and make it hollow to specified dimension.

Flex

This function can be used to perform a variety of functions such as bending, twisting etc. The user inputs include the object/body that’s to be bent and the angle to which it is to be bent.

Combine

This feature lets us primarily to add or subtract two or more parts of a body

Split

This feature splits bodies to fragments when proper trim tools are assigned.

Move/copy

As the name suggests, this feature helps user to copy/move features from one place to another

Pattern/mirror features

These features are primarily used to copy a part/body in a certain geometrical pattern

Linear pattern

As the name says, this feature lets the user to copy a part/body in a linear pattern

Circular pattern

As the name suggests, this feature lets the user to copy a part/body in a circular pattern

Mirror

This feature can be used when the user wants to mirror a part/body about a particular prescribed axis.

Curve driven pattern

This feature is similar to the linear or circular pattern. The only difference is that the pattern is laid based on the curve input given by the user.

Surface features

The following features deals with the surface aspect of the solid work parts

Like we saw previously, the common functions like Extrude, Revolve, Loft, Sweep are also present for surface creation. The working and usage of such common features are the same except for the type of bodies it generates.

Boundary Surface

This tool lets the user create a surface when bounded by 4 boundary curves. There boundary curves are often placed under different direction options to yield desired surfaces.

Ruled surface

This feature is used when the user wants to use a edge to create ruled surfaces. The user has the freedom to oriented their ruled surfaces about any direction by opting for proper options.

Fill

This feature is similar to the boundary surface creation feature. But the only difference is that it does not have any constraints related to the number of bounding curves like we saw previously in boundary surface.

Extend

This feature can be used to extend selected surfaces to a user mentioned limits.

Trim

This feature is used when the user wants to trim a surface with respect to a sketch. The sketch with respect to which to which the surfaces are to be trimmed is selected as the trim tool.

 Knit

This feature is used when the user wants to knit together 2 or more surfaces. Tangent surfaces are indicated by dotted lines when knitted feature is applied between them.

Curve features

The following features help users to manipulate curve inputs.

Split line

This feature can be used to split 2 surfaces/bodies about a curve.

Projected

This feature can be used primarily for 2 functions

    1. Create 3D curves using two input 2D sketches.

2. For projecting curves onto surface/bodies.

Reference geometry

These geometries are created to support/aid in making surfaces/bodies effectively.

Plane

This feature helps us in creating planes in different orientations based on user inputs. These planes can be later used for sketching and many such operations.

Axis

Similar to planes as reference geometry, axis can also be used as reference geometries. This features lets user to create axes along different directions and orientations based on user inputs.

Sketch picture

This feature lets user import reference blueprints for creating sketches and bodies. These blueprints can be inserted in all planes (Front, right and top planes) and worked upon to get a wholesome idea for a 3D body.

Conclusion

Working on this project helped me gain strong surface modelling and rendering skills. I ventured through different features and options to mend the complex surface flow of the car. This helped me gain confidence over the design tool.
