YACHT MODELLING
OBJECTIVE:
To Model, a YACTH using SolidWorks part file, Assemble all the individual parts using Solidworks Assembly File and performing attractive rendering using Solid Visualize and PhotoView 360.
INTRODUCTION:
A Yacht is a sail or power vessel using for pleasure, cruising, or racing. There is no standard definition so the term applies to such vessels that have a cabin with according overnight use, to be termed a Yacht as opposed to a board pleasure vessel is likely to be at least 33 feet in length and may have judged to have good aesthetic qualities.
Originally, all yachts are made of wood, using a wooden keel and rib, clad with planks. these materials were supplanted with iron or steel yachts. in the 1960s fibreglass became a prevalent material. these materials and others continue in use. Whereas yachts of 79 feet and below may be constructed of fiberglasses, larger yachts are likely to be constructed of steel, aluminium, or composite fibre-reinforcement plastic.
Top-down and Bottom-up:
In top-down assembly design, one or more features of a part are defined by something in an assembly, such as a layout sketch or the geometry of another part. The design intent comes from the top, which is the assembly and moves down to the parts.
Bottom-up design is the traditional method. Your first design and model parts, then insert them into an assembly and use mates to position the parts. To change the parts, you must edit them individually. These changes are then seen in the assembly.
This Yacht Assembly is designed in the Buttom-up method.
DESIGN METHODOLOGY:
DESCRIPTION :
Rendering of the individual parts was done in SolidWorks Visualize Professional '2019'. The Real View graphics were enabled for efficient rendering. No dedicated cameras and scenes were created for this purpose.
(I) Setting up the Blueprints :
* All the blueprints were imported into a SolidWorks part file using the path: Tools - Sketch Tools - Sketch Picture.
* Appropriate positioning as well as scaling of the blueprints is very important and has to be done perfectly as shown.
* This Blueprint setup is then used to model all the parts.
(II) Modelling the 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, performs an action that is similar to Archimedes' screw. It transforms rotational power into linear thrust by acting upon a working fluid, such as water or air.
* The propeller is modelled simply by using solid modelling features such as - Revolved Boss/Base, Extruded Cut, etc. Initially, a single blade is modelled using the Lofted Boss/Base feature. It is then using in the Circular Pattern feature to model the rest of the blades.
* Fillets are added to remove off the sharp edges, provide appropriate curvature to the periphery of the blades and improve the outlook of the propeller.
(III) Modelling the Radar :
* Marine Radars are X band or S-band radars on ships, used to detect other ships 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.
* The Radar is modelled very easily using the following features - Extruded Boss/Base, Cut Extrude, Fillets, etc. Since the radar is symmetric in shape, only half the portion is modelled. The other half is simply mirrored using the Mirror feature. The Merge Solids option is enabled while doing so.
* A text is added on the surface just for the sake of a better and realistic outlook.
* The text feature can be found at the mentioned path: Tools - Sketch Entities - Text.
* This text is then projected on the radar surface using the Split Line command.
(IV) Modelling the Yacht Hull and the Garage door :
* A Hull is the watertight body of a ship or boat. The hull may open at the top (such as a dinghy), 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.
* Here, the hull is essentially modelled by Surface Modelling. The outer surfaces of the Hull are created using the features in the Surfaces tab.
* For this, the Project Curve feature along with the different sketch tools, is used to create the outer peripheries of the surfaces. Then, the surfaces are created using these curves and by using features such as Lofted Surface, Boundary Surface, Extruded Surface, Trim Surface, etc.
* The Port Holes are modelled by using the Swept Boss/Base features after using Extruded Cut.
* The railing is modelled by creating projected curves through different sketch tools and then by using the Swept Boss/Base command with the curves as the sweep path.
* Fillet is used at all the required places where sharp edges are to be avoided. Also, providing fillets around the windows gives a good aesthetic appeal to the model.
* The Anchor is modelled directly as a solid i.e by using the features such as - Extruded Boss/Base, Extruded Cut, etc.
* These two symmetric parts are then carefully knitted together using the feature Knit Surface. The Create Solid option is enabled to fill the inside portion of the Hull. While doing so, it is ensured that the knitting is done properly. This can be
done by carefully looking at each and every edge. A perfectly knitted edge looks black in colour, while a blue edge means that there is no association between the two faces altogether.
* To give a more realistic outlook, decals are added on the deck surface as well as the stair surfaces. Since the Hull is symmetric, only half the portion is modelled, the rest half is mirrored using the Mirror feature. Appearances are changed by providing colours at all the required faces. This gives the model a perfect and realistic look.
* Now, the Garage door is simply modelled using the garage portion which was carved out of the Hull.
* The unnecessary portion is removed off by using the Extruded Cut feature. Fillets were provided to blend the sharp edges.
(V) Modelling the Seats :
* Seats are modelled either by solid features or by using surface features.
* There are three seatings in the model - Front, Middle and Rear.
* Here, the Front and the Rear seats are modelled by first creating the outer surfaces using the features of the Surface tab. Then by creating a solid after carefully knitting the surfaces together using the Knit Surface feature.
Front Seat :
Middle Seat :
Rear Seat :
(VI) Modelling the Superstructure :
* On watercraft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck.
* This does not usually include its masts or any armament turrets. Here, the Superstructure is also modelled by creating the outer surfaces first, just as we did in the case of Hull.
* These surfaces are then mirrored using the Mirror command and then knitted together properly with the Knit Surface.
* Here as well, the railings are modelled by using the Swept Boss/Base feature.
* The Jacuzzi is just a cutout with a surface at the top to represent the water level.
* The surface is given a transparent appearance for this purpose.
* The window edges are blended using the Fillet feature to give a smooth appearance.
* The vipers are modelled using solid features such as Extruded Boss/Base, Extruded Cut, Swept Boss/Base, etc. along with appropriate Chamfers and Fillets.
(VII) Modelling the Radar Mast :
* The Mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp. Large ships have several masts, with the size and configuration depending on the style of the ship.
* Here, the mast consists of 2 light bulbs alongside 2 antennas.
* This mast is easily modelled using solid features such as Extruded Boss/Base, Revolved Boss/Base, Swept Boss/Base, etc.
* The horns are modelled by using the Shell feature. This feature essentially removes the inside material out of a solid 3D part, thereby making it hollow.
* The Mirror feature is used to mirror-symmetric entities.
(VIII) Creating the Assembly :
* All these individual parts are then assembled together using the SolidWorks Assembly file.
* First off, the Hull is fixed at the proper location. Rest all the parts are then located with respect to this fixed Hull.
* Standard Mates such as Coincident, Tangent, Concentric, Parallel, etc are used to provide appropriate constraints.
* Shown below are the standard vies of the Assembly -

Render:
* Available Decals are added to enhance the outlook of a few of the parts.
* The yacht Assembly is rendered using the Add-in- Solid works Visulaze tool provided by SolidWorks.
* proper Scene is crated for the Render. An appropriate environment is set up for this purpose. Also, a suitable Backplate is chosen out of the library.
* The perspective view is enabled to ensure a real-time look.
* Now, after providing a suitable appearance the model is rendered.
CONCLUSION:
Thus, the complete exterior body parts of a sunscreen predator Yacht are Modeled in Solidworks part files, assembly in SolidWorks assembly file then the assembly is rendered using SolidWorks Visualize.
