> FINAL PROJECT REPORT

SUNSEEKER PREDATOR YACHT

AIM

- To learn about different features of solidworks in solid modelling and surface modelling to create a 3D model of a Sunseeker Predator Yacht.

OBJECTIVES

- To learn about surface modelling and solid modelling to create different parts of the yacht.

- To create assembly of the yacht.

- To learn about Photoview 360 to do photo realistic renedering of the yacht.

INTRODUCTION

A Solidworks model consists of 3D solid geometry in a part or assembly documents. Drawings are created from models or by drafting views in a drawing document. Typically, begin with a sketch, create a base feature and then add more features to the model.

In this project we will discuss about the design approach and different features of the solid modelling and surface modelling.

> Solid Modelling

- Solid modelling is the process of constructing a 3D model through a series of additive and subtractive operations while always maintaining a calculable volume.

> Surface Modelling

- Surface modelling is the process of constructing a 3D model through the process of defining each of the faces that are present in its geometry.

DESIGN APPROACH

> There are mainly 2 types of approaches.

1. Top-down Approach

This is also known as stepwise design. This is a system design approach where design starts from the system as a whole. Complete system is then divided into smaller sub-applications with more details.

2. Bottom-up Approach

This is a system design approach where parts of the system are defined in details. Once these parts are designed and developed, then these parts or components are linked together to prepare a bigger component. This approach is repeated until the complete system is built.

> 3D Modelling Features

- Boss/Base Extrude

It is used to extend a sketched profile in one or two directions as either a thin feature or a solid feature.

- Boss/Base Revolve

It is used to create a solid model around an axis. It is used to revolve the sketch around an axis to add material to it.

- Boss/Base Loft

Loft creates a feature by making transitions between profiles. Loft can be created by using two or more profiles.

- Boss/Base Sweep

This is the one feature that help sweep a closed profile along a closed or open path.

- Boss/Base Thicken

It is used to create a solid feature by thickening one or more adjacent surfaces.

- Cut Extrude

Cut extrude feature removes material from the part.

- Circular Pattern

Circular pattern is used to create multiple instances of one or more features that can be space uniformly around an axis.

- Mirror

It is used to create a copy of a feature or multiple features, mirrored about a face or a plane.

- Dome

It creates a dome that is tangent to the adjacent cylindrical or conical face.

- Shell

The shell tool hollows out a part, leaves selected faces open and creates thin walled features on the remaining faces.

- Split

Split feature is used to create multiple parts from an existing part.

- Chamfer

The chamfer tool creates a bevelled feature on selected edges, faces or a vertex.

- Fillet

It creates a rounded internal or external face on one or more edges of a part, between two face sets or between three adjacent face sets.

> Surface Modelling Features

- Surface Loft

Loft surfaces are surfaces generated by multple curves or existing edges creating a smooth tangency between the selected curves. This tool is very valuable for modelling complex surfaces.

- Surface Sweep

Sweep surfaces are surfaces that are generated from a section curve positioned along a path.

- Surface Extrude

Surface extrude is used to extrude the boundary edges of a face of a solid body or edges of a surface body in a customized direction.

- Ruled Surface

The ruled surface command creates surfaces that extent out in a specified direction from selected edges.

- Surface Extend

Surface extend command is used to extend a surface by selecting an edge, multiple edges or a face.

- Surface Fill

This feature constructs a surface patch with any number of sides, within a boundary defined by existing model edges, sketches, or curves, including composite curve.

- Surface Knit

Surface knit is used to combine two or more faces and surfaces into one.

- Surface Offset

Surface offset tool creates a new surface body from an existing set of faces.

- Surface Trim

Surface trim is used to trim unwanted surfaces. That surface must be intersecting with any surface, plane or has a sketch on its face.

PART MODELLING

> Main parts of the Sunseeker Predator Yacht

Propeller
Radar
Hull
Garage Door
Superstructure
Front seat
Middle seat
Rear seat
Radar mast

> BLUEPRINT SETUP

- Blueprint is a guide for making something. It is a design or pattern that can be followed.

- To setup the blueprints in solidworks, follow these steps:

Open Solidworks.
Create new part file.
Select any plane and create new sketch, then go to Tools > Sketch tools > Sketch picture, then browse the image respected to the selected plane.
Change the different properties like dimensions, position and transparency as required and then close the sketch.

2. Radar

- A radar device acts as a major navigation aid for boaters. It helps in detecting boats, birds, landmasses and weather systems even if the visibilty is less than usual.

3. Hull

- The hull of a yacht is the most notable structural entity of the yacht. To define the hull, it can be said that it is the watertight enclosure of the yacht, which protects the cargo, machinery, and accommodation spaces of the yacht from the weather, flooding and structural damage.

ASSEMBLY

> Appraoch

- As discuss in the introduction, here Bottom-Up Assembly approach is used. All the parts are made seperately in the part file in solidworks and then bring them all together in assembly file.

- In solidworks, part file is save as .sldprt and assembly file is save as .sldasm.

> Mates

There are mainly 3 types of mates which are used to create assembly in solidworks.
