MODELING, ASSEMBLY, PHOTOREALISTIC RENDER OF AN SUN SEEKER PREDATOR YACHT

OBJECTIVE

Main objective of this project is to Create a photo-realistic Conceptual model of an sunseeker predator yacht using solid works.By creating part drawings, converting them to 3D models, assembling the created parts and finally giving it a photorealistic view by rendering the model using Photoview-360.

INTRODUCTION

SOLIDWORKS

Solid works is a 3D-Modelling Computer Aided Design (CAD) and Simulation based software. To create a 3D Model, it uses the parametric future based approach (Developed by PTC) by taking the inputs from the user

YACHT

A yacht is watercraft used for pleasure or sports. The term originates from the Dutch word jacht (which means "hunt"), and originally referenced light, fast sailing vessels that the Dutch Republic navy used to pursue pirates and other transgressors around and into the shallow waters of the Low Countries.

Today's yachts are almost exclusively for leisure. A yacht is any sail or power vessel used for pleasure, cruising, or racing. The word often connotes luxury; however, luxury is not a quality necessary to meet the definition; nor is it always desirable. Many racing yachts are stripped-out vessels with a minimum of accommodations to lower weight.

DESIGN METHODOLOGY

Idea is the primary requirement to design/model any product.

In this project the blueprints are taken as the base files for the construction of the yacht Model. Blueprints are arranged and saved as the blueprint setup for the base of the modeling

MODELLING

The Predator yacht consists of

• Hull
• Front seat
• Middle seat
• Rear seat
• Superstructure
• Garage door
• Propeller
• Radar
• Radarmast

The major Tools/Features used in the solid works for modeling the chopper were

1.Creating a 2D sketch:A 2D sketch is the base to create a 3D model. It is usually created on the X-axis & Y-axis. This includes lines, circles, rectangles, splines, etc.

• The Status of a Sketch
  The current status of a sketch is displayed in the lower right corner of the screen.
  Fully Defined = Black
  Under Defined = Blue
  Over Defined = Red

2.Geometric relation: Geometric relations are one of the most powerful features in SOLIDWORKS.They’re used in the sketch level to control the behaviors of the sketch entities when
they are moved or rotated and to keep the associations between one another

3.Project curve:

• Click Project Curve on the Curves toolbar, or Insert > Curve > Projected.
• In the PropertyManager, under Selections, set Projection type to one of the following:
• Sketch on faces
• Use this selection to project a sketched curve onto a model face.
• Under Sketch to Project , select the curve in the graphics area or from the flyout FeatureManager design tree.
• Under Direction of Projection, select a plane, edge, sketch, or face as the direction of the projected curve.
• Under Projection Faces , select the cylindrical face on the model where you want to project the sketch.
• Select the Reverse projection check box, or click the handle in the graphics area, if required.
• Select Bi-directional to create a projection that extends on both sides of the sketch

4.lofted surface:

2.Superstructure :

• A superstructure is an extended construction of any building or platform that rises above the rest of the building or platform in a distinct manner. Thus, superstructure 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
• The size of the superstructure has a great influence on the mobility of the vessels. They are designed in a manner, so that, they add value and hinder the speed and mobility in the least.

5.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 which is similar to Archimedes' screw. It transforms rotational power into linear thrust by acting upon a working fluid, such as water or air.

6.Radar :

• Radar will show what is around the boat, seeing through darkness, precipitation and poor visibility. Whether you’re crossing a busy shipping channel in thick fog, looking for squalls offshore, or identifying a harbour entrance in the dark, Radar offers a significant aid to navigation and safety.
• It works by sending out a radio signal. When the signal hits an object, it gets reflected back to the radar, which can then calculate a rough estimate of the object. It does so by detecting other ships and land obstacles, to give bearing and distance for collision avoidance and navigation while on water
• Features used for this model are Boss Extrude, Cut Extrude, Mirror, Sketch Pattern, fillet and Split line

ASSEMBLY OF PREDATOR YACHT

• All the parts were assembled in a Solidworks Assembly file by inserting each part, one after the other using suitable mate relations.

1.Mates: Mates create geometric relationships between assembly components. As you add mates, you define the allowable directions of linear or rotational motion of the components. You can move a component within its degrees of freedom, visualizing the assembly's behavior. Some of the mates used during the assembly process are coincident, distance, angle, concentric, parallel, width, limit angle
