Assembly and Modeling of the Yacht:

Objective:

• The objective of this project is to create part models of the Yacht and assembly the parts using Solidworks.
• To add Decal, Camera view, and Environment Scene of the assembly.
• To create the photo-realistic Model of this Yacht assembly and rendering the assembly using Solidworks Phtotview 360.

Introduction:

This project explains the designing of different parts of the Yacht and assembling them to get a complete model of the Yacht using Solidworks. It also tells about the rendering of the model using Solidworks 360 to make the Yacht more natural and realistic.

Modeling and Assembly Features:

The various modeling features used for modeling the Yacht are discussed as follows:

• EXTRUDE BOSS/BASE:

Extrude Boss/Base is one of the important and very useful tools in Solidworks CAD software to create solid 3D models. It extrudes a sketch or selected sketch contours in one or two directions to create a solid feature. That means, if you have a closed contour sketch drawing, then you can add materials to that contour and convert it into a 3D model.

• EXTRUDE CUT:

Extrude cut is another cool feature that helps to remove materials from the 3D model. It is just the opposite of to extrude boss/base feature because it cuts a sketch profile while extruding. You can cut in both directions and are mainly used for creating holes, channels, slots, etc.

• REVOLVE BOSS/BASE:

Revolved Boss or Base is a SolidWorks feature tool that is used to create a solid 3D model around an axis. You can revolve the sketch around an axis to add materials to it. You can access revolved boss/base from both command manager and menubar.

• SWEEP:

SWEEP is the one feature in Solidworks that helps sweep a closed profile along a closed or open path. In this session, we are going to use a simple 3D object as an exercise to demonstrate the use of the SWEEP command in Solidworks.

• FILLET:

A fillet is a tool used to round an edge, vertex, or face on both inside and outside of a 2D or 3D model. The fillet type, location, and radius of the fillet are defined.

• CHAMFER:

SolidWorks chamfer tool is one of the useful tools, which helps to cut (45-degree angle with the normal surface) or make edges or corners (vertex) of 3D model in straight.

• MIRROR:

The mirror tool in Solidworks is used to copy a 2D or 3D object about a reference line or plane. Creates a copy of a feature, (or multiple features), mirrored about a face or a plane.

• SHELL:

In Solidworks, Shell feature having their own property manager which controls the application of the shelling process on designed models. Here, both uniform thickness and multi-thickness shelling can be easily done by using this feature tool.

• LINEAR & CIRCULAR PATTERN:

The Linear Pattern Command is used to drive features, faces, or bodies in a linear direction. The Circular Pattern Command is an excellent tool used to replicate features, faces, or bodies in a rotational manner about an axis.

• PROJECTED CURVES:

A projected curve is a 3D curve that represents the intersection of two extruded surfaces of two sketches on intersecting planes.

• SURFACE EXTRUDE:

In SolidWorks, the Extruded Surface tool is provided to extrude a closed or an open sketch to create an extruded surface.

• SURFACE LOFT:

The loft feature is an important tool for (surface) modeling in SolidWorks. The loft feature creates a shape by making transitions between multiple profiles and guide curves. This tool is very valuable for modeling complex surfaces.

• SURFACE SWEEP:

Sweep creates a surface by moving a profile (section) along a path. A sweep can be simple or complex. To generate the swept geometry, the software creates a series of intermediate sections made by replicating a profile at various positions along the path.

• SURFACE FILL:

The surface fill joins the solid, removing the features inside. The model with Filled Surface applied and Merge result cleared. The surface fill creates a new surface, and the features inside remain. Forming a solid is possible if all the boundary entities are open surface edges.

• SURFACE TRIM:

To trim a surface, Create two or more surfaces that intersect at one or more points, or create a surface that intersects with a plane or has a sketch on its face.

• Mates:

Mate operation is the basic tool for assembling the parts. Mates are used in SOLIDWORKS to constrain and connect different parts in an assembly. There are various mate operations such as coincident, parallel, perpendicular, tangent, concentric, lock, etc.

Designing Approach:

Modeling of the Yacht:

Propeller:

A propeller is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral, that, when rotated, exerts linear thrust upon a working fluid, such as water or air. Propellers are used to pump fluid through a pipe or duct or to create thrust to propel a yacht boat through water or an aircraft through the air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade which exerts a force on the fluid.

Propeller is modeled by fully defined sketches, features used like revolve, loft, filets extrude cut, circular pattern. Add appearance to the propeller.

Hull:

A hull is the watertight body of a ship, boat. The hull may open at the top, or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design.

There are three basic types of motor yacht hull: full-displacement, semi-displacement, and planing, which have progressively higher cruise speeds and hourly fuel consumption with increased engine power.

• Full-displacement hulls move the water up and out of the way of the vessel, making a wave. They are limited in speed by the square root of the waterline length multiplied by a factor, depending on the units used. Added horsepower cannot increase the maximum speed, only the size of the waves produced.
• Semi-displacement hulls allow speeds that are faster than the hull speed of a displacement vessel because they rise somewhat out of the water and create smaller waves. They also provide greater comfort than planning hulls.
• Planing hulls require sufficient power for the boat to slide up onto the surface, which avoids the need to use power to lift water out of the way of the vessel. Such vessels have flat surfaces on the undersides.

The Hull is modeled by fully defined sketches, features used like revolve, loft, filets, extrude, extrude cut, linear pattern, surface extrudes, surface loft, surface trim, extend surface, surface sweep, sweep boss/base, surface fill, etc. Add different appearances to the parts of the hull for looking good and realistic view.

Front Seat, Middle seat, and Rear seat:

A yacht seat is designed primarily for comfort. It is usually an upholstered armchair with a slightly inclined back. The seats is modeled by fully defined sketches, features used like revolve, loft, filets, extrude, extrude cut, surface extrudes, surface loft, surface trim, extend surface, surface sweep, sweep boss/base, surface fill, etc. Add different appearances to the parts of the hull for looking good and realistic view.

Super Structure:

A superstructure is an upward extension of an existing structure above a baseline.

On watercraft, the superstructure consists of the parts of the ship or a boat, that project above its main deck. This does not usually include its masts or any armament turrets.

The size of a watercraft's superstructure can have many implications in the performance of ships and boats since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly.

The height and the weight of the superstructure on board a ship or a boat also affect the amount of freeboard that such a vessel requires along its sides, down to her waterline. In broad terms, the more and heavier superstructure that a ship possesses (as a fraction of her length), the less the freeboard that is needed.

Radar and Radar Mast:

Radars on ships or boats are used to detect other ships or boats and land obstacles, to provide bearing and distance for collision avoidance and navigation at sea. They are electronic navigation instruments that use a rotating antenna to sweep a narrow beam of microwaves around the water surface surrounding the ship to the horizon, detecting targets by microwaves reflected from them, generating a picture of the ship's surroundings on a display screen.

RADAR RADAR MAST

Garage Door:

The garage door is mainly used to keep hidden the things in the garage. It is the closing of the garage on the boat or ship. It is designed according to the need of shape and design. The Garage Door is designed from the split part of the superstructure. First design half part and then mirror about the midplane.

ASSEMBLY OF THE CHOPPER:

All the parts modeled were imported to assemble them. In assembly, the mating feature was often used to locate and relate the parts with one another. The hull was inserted initially and fixed. The other components were inserted and set with a reference to the hull.

• RENDERING OF THE YACHT:

In rendering, the Sunseeker Predator Yacht was made to set up in such a way to look natural and unique. Decals were added to the body parts. Views and light directions were changed. Using Solidworks Photo-view 360, the appearances, background scenes, and camera views were changed. Then final rendering was done to make the chopper, a cool and realistic one.
