Introduction:-
A yacht is a watercraft used for pleasure or sports. Today's yachts are almost exclusively for leisure. A yacht is any sail or power vessel used for pleasure, cruising, or racing. Until the 1950s, almost all yachts were made of wood or steel, but a much wider range of materials is used today. Although wood hulls are still in production, the most common construction material is fibreglass, followed by aluminium, steel, carbon fibre, and ferrocement. Apart from materials like carbon fibre and aramid fibre, spruce veneers laminated with epoxy resins have the best weight-to-strength ratios of all boatbuilding materials.
In recent years, these yachts have evolved from fairly simple vessels with basic accommodation into sophisticated and luxurious boats. This is largely due to reduced hull-building costs brought about by the introduction of fibreglass hulls, and increased automation and "production line" techniques for yacht building. Most basic yachts have electric lighting, radio and navigation aids such as GPS. Aids such as radar, echo-sounding and autopilot are common.
Part Modeling :
- Part Modeling you can create a part from a conceptual sketch through solid feature-based modeling, as well as build and modify parts through direct and intuitive graphical manipulation.
Surface Modeling :
- Surface modeling gives you the ability to build out a visual representation of an object’s exterior and its contours. In other words, it’s a surface.
- Surface modeling plays a major role in modeling a yacht. Most of the parts in the yacht are surface modeled.
- The following are the features used in surface modeling,
- SKETCH- 2D-To create sketches on a plane reference
3D-To create sketches in the three dimension
- Lines- To create a line or centerline
- Circles- To create cirlcular shape
- Rectangles- To create rectangular shape
- Splines- To create curved lines controllable through handles
- Slots- For creating slot shape
- Arcs- for creating arcs or half circles
- Offset Entities- To offsetting the sketch at required distance
- Convert Entities- To convert sketches from plane to another plane
- Trim Entities- For deleting or trimming the sketch
- Extruded Boss/base- To create 3d object
- Extruded Cut- For cutting a portion from 3d Object
- Revolved Boss/base- To revolve a circular shape around axis
- Lofted Boss/base- To create surface between multiple curves
- Surface Extrude- For creating surface
- Trim Surface- To Trim Surface
- Loft Surface- To create surface between multiple curves
- Sweep Surface- For creating surface of sketch over a curve
- Sweep Cut- To remove material along curved 3d shape
- Extend Surface- To increasing the length of surface
- Knit surface- To join or knit multiple surfaces
- Fillet- To Create round edges
- Chamfer- To make slope(in Angle)
- Dome- For making Round or circular shape on an end
- Sweep- To create a 3d shape from 2d shape along a connected path
- Split- To create multiple part from single part
- Shell- To removing inner material to form hollow shape
- Mirror- To copy sketch/Feature and Body from one side of a plane or axis to another
- Patterns- For creating same shapes or objects to another place by reference of any line or plane in linear, curve
- Combine- To combining or adding bodies to make them single body
- Appearences- To give parts their material look and painted colour
PARTS CONSISTS IN THE YACHT
- Propeller
- Radar
- Blue Print
- Hull
- Garage Door
- Front Seat
- Middle Seat
- Rear Seat
- Super Structure
- Radar Mast
- Propeller :
- A Propeller is a fan mechanism that transmits power by converting rotational motion into thrust. Usually consisting of 3 or more blades.
Features used to create Propeller
- Sketch
- Revolve
- Cut Extrude
- Loft
- Fillet
- Circular Pattern
Sketch
- Sketch is the two dimensional representation of the model with respect to the plane/view from the outside of the mode.
Revolve
- To create a revolve feature: Create a sketch that contains one or more profiles and a centerline, line, or edge to use as the axis around which the feature revolves.
Circular Pattern
- Circular pattern is used to create a pattern of the propeller. By using this multiple patterns are created.
Loft
- Loft are surfaces generated by multiple 3D Curves or existing edges creating a smooth tangency between the selected curves.
2. Radar
Radar is 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. A Radar has a flat antenna that spins, emitting a signal, then listening back for that signal. The return signal bounces back at varying times based on what it may be bouncing off of.
Features used to create Radar
- Sketch
- Extrude
- Mirror

- Hull :
- A hull is the watertight body of a ship or boat. The hull may open at the top or it may be fully or partially covered with a deck.

- Super Structure :
- Superstructure is an upward extension of an existing structure above a baseline. It consists of the parts of the ship or yacht (in this case) that project above her main deck. The size of a watercraft's superstructure can have many implications in its performance, since these structures can alter their structural rigidity, their displacements, and/or stability. It encloses the cabin and living area of the yacht. They are designed in a manner, so that, they add value and hinder the speed and mobility in the least.
- It was designed after importing the deck surface of the Hull as interface surface. Its designing required precise curvature during the sketching stage to avoid any bad geometry from showing up in the modelling stage. It means to add a construction to an already existing structure. In ships this is the name given to the part of the ship that emerges from the deck.

RENDERING
The rendering is a process in which a simple design is converted into a realistic appearence design. The environments, camera view setup, lightning, shadows, etc can be controlled and edited with the help of photoview 360 and visualize.
