MODELLING AND RENDERING OF AN PREDATOR YACHT

Objective:-

The objective of the project is to design and model all parts of Predator Yacht and assembly.

Introduction:-

In this project we concentrate on solid modelling and Surface Modelling to model a Predator Yacht. Every single part was design in solidworks. Then all parts were assembled by adding mates to create Realistic image of the yacht.

SOLIDWORKS Visualize is a Realistic Rendering Tool that takes our assembly model to create quality images.

Photo-view 360 is a Solidworks add-in which also produces realistic models by changing scenes, decals, lightning effects and different appearances.

DESIGN SEQUENCE

In this project, we build a Predator yacht using solidworks to understand the 3D – Modelling methodology of Surface Modelling.

The following are the parts which we have modelled in Surface modelling using SOLIDWORKS,

• Blueprint set-up
• Modelling of Propellor, radar
• Modelling of Hull, Garage Door
• Modelling of Rear seats, Middle seats and Front seats
• Creation of Superstructure
• Assembly of Predator Yacht

TYES OF COMMANDS AND ITS EXPLANATIONS

Sketch – Every model usually begins with a sketch. Then we can apply dimensions and features.

3-D SKETCH

When sketching in 3D, we can snap to X, Y & Z direction and constraints are applied along those direction respectively.

SKETCH COMMANDS

Following are the sketch commands

• Line
• Circle
• Rectangle
• Spline
• Sketch Fillet
• Point
• Offset Entity
• Sketch Picture
• Convert Entity

FEATURES COMMANDS

• Extruded Boss/Base - This command allows us to take 2D sketch and apply thickness to it.

• Extruded cut- In this we can remove material by projecting sketch normal to plane.

• Split – Lines or splines are used to divide faces into two.

• Dome – It can add or calculate distance using radius of arc.

• Pierce – The pierce relationship is used in sweep.

• Project Curve- Select Bidirectional to create a projection that extends on both sides of the sketch. The curve can be used as a path for a sweep.

• Wire Frame - Wireframe ia s view mode in which all edges of part or assembly are displayed.

1. SURFACE MODELLING

Surface modelling focuses more on the external body. The process requires us to convert between 3D modelling types. The surfaces are generally used to create models of complex shapes. We can covert surface models in solid models.

• SURFACE COMMANDS
• Lofted Surface – It creates a lofted surface between two or more profiles or sketches. We have to specify start and end constraint and add guide curves to control the path shape.

• Extend Surface – Extends one or more edges or faces on a surface, based on extension type.

• Extruded Surface – Extrudes a sketch or selected sketch contours in one or two directions.

• Revolved Surfaces – Revolves a sketch or selected sketch contours around an axis to create a surface feature.

• Ruled Surface – Inserts ruled surfaces in a specified direction from edges. We can select four types such as Tangent to surface, Normal to surface, Perpendicular to vector and tapered to vector.

• Filled Surface – We can use this feature to construct a surface to fill gap in a model. This feature constructs a surface patch with any number of sides within a boundary of existing edges.

• Trim Surfaces – It trim the surface where it intersects with another surface, plane
• Offset surface – This allows us to create an offset surface with gaps, by specifying required distance.

• Mirror Surface- Using this we can get exact replica of selected feature. We can mirror about Plane, faces. If the original feature or sketch is modified, the mirrored copy is updated to reflect the change.

• Swept Surfaces – It sweeps a closed profile along an open or closed path to create surface feature.

• Reference Plane – We can create planes in part, we can use planes to sketch, to create a section view of model.

• Projected curve – A projected curve is typically used either in sweeps and loft as path or guide curves.

• Split Line – The Split tool projects an entity to surfaces. It can divide a selected face into multiple separate faces.
• 

• Fillet – A fillet is a rounding of a corner or edge in a sketch or an edge on a surface.

• Chamfer – The chamfer tool creates a beveled feature on selected edge, faces, or a vertex.

PARTS OF YACHT AND ITS FEATURES

1)BLUEPRINT

A blueprint is a reproduction of a technical drawing using contact print process on light sensitive sheets. At its most basic, a blueprint is a production of an image that already exist. These are easier to read and faster to make.

The below shown Blueprint was used to model the yacht. For setting up blueprint, the sketch pictures were used and placed with their respective distances.

2)HULL

A hull is a 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. The line where the hull meets the water surface is called the waterline.

The first step for modelling yacht was creating a blueprint of it. Then curve has projected to get the shape of hull using splines. After that we created a lofted surface and trim unwanted surface. Another surface was created by using offset and filled the surface by using surface fill feature. Deck surface was created using boss extrude. All the windows and portholes were created using extrude cut and fillets were added. Then we created a rail at bottom and chamfer, it. By using slot option, the Rope hangers were extruded and Dome was applied and then Line pattern wea used. Then windows, staircase and hand support were created railings around the was generated with the help of blueprint. By using 3 D sketch we created Axle of propellor and surfer by applying Revolved boss/base. Then Anchors were created by sketching the first half and extruded using extrude boss and other half was mirrored. Finally, the Garage was created using extrude cut. And rest of the features we mirrored and saved the part.

3)RADAR

Marine radars are short range radars used for locating other ships and land in the area. Ship radar are used as tracking ship devices. 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.

We draw required sketch of the body and radar was created using extruded Boss. By using sketch pattern holes were created and then applied extrude boss and cut feature. The Radar has a circular slot underneath which was created using extrude cut. The half was mirrored, Then Text over the Radar created using Text option. Then applied fillet wherever required and finally part was saved by adding appearance.

4)PROPELLER

There can be one, two or three propellors. It is the most important part of the ship without which a ship can’t move, so the main function of propeller is to propel the ship in the forward direction by producing thrust on water. It is based on Newton’s third law of motion and Bernoulli’s theorem.

The centre portion of the Propellor was sketched and revolved using Revolved boss. Then the blades were created using Reference Plane, Lofted boss and fillet. Then the remaining five blades were created by using circular pattern. Then the centre circular portion was removed by extrude cut and finally part was saved by adding appearance.

5)GARAGE DOOR

Garage door is a large door on a garage that opens either manually or byb an electric motor. Garage doors are large enough to accommodate automobiles and other vehicles. The operating mechanism is spring -loaded or counterbalanced to offset the weight of the door and reduce human effort required to operate the door.

In this we split the solid body while creating Hull to model the Garage Door. Then we applied extrude cut and chamfered the face for the Door creation. Then solid body of Garage door was created by shell feature and filets are applied. Then created Door holders on both sides using extrude cut. Then we apply mirror to get the whole body. After that Text over the Garage door was created using Text option in sketch feature, finally by adding appearance part was saved.

The front seat in our model was placed before the superstructure and also it has sun pads rest on it. Front seats are the two connected seats that are built back-to-back from one and other. They have a built-in storage unit underneath them.

The front seat of the yacht was also created with the help of Blueprint. The first half was modelled and half was mirrored. The front seat was placed before the superstructure. The body of the Front seat was modelled using swept surface, extruded surfaces, filled surface, lofted surface and unwanted part was removed using trim surface. Then four Rest Beds were created using Extruded boss and Dome was created over the face of the beds separately. Then the required fillets and chamfers were applied with extruded thin surfaces.

Often it is called as Bridge or Deckhouse. A superstructure is an upward extension of an existing structure above a baseline called ground level.

The deck surface from the hull was imported and then the superstructure was modelled over it. The side surface of the superstructure was created by using Extruded surface, lofted, filled and trim surface and then knitted the surface. The front edge of the superstructure was provided with a water feature which was created by using extruded boss, extruded cut and filled with a water appearance windshield was created by extruded cut and the wipers were created using 3D sketch and reference plane with the help of swept boss/base. The portholes for the superstructure were created by using extruded surface trim and extended surface. Ruled Surface was used to fill the left-out edges.

The back Doors of the superstructure was created using extruded cut, filets and reference plane. Then all the surfaces generated were knitted to form a solid body. The superstructure consists of two surface bodies and five solid bodies. One of the surfaces of superstructure was used to place the Radar Mast so it was named as Radar Mast Reference.

Then rest half was mirrored by applying proper fillets and appearance and part was saved.

ASSEMBLY

In this, whole existing parts of model are taken and give mates like coincident, concentric, etc.

Assembly Procedure

• We have imported all the parts manually by using insert component option.
• Advanced mate was also used wherever required.
• Then fix the hull part by applying coincident mate.

• Then for each part we applied necessary mates required by the blueprint using coincident mates, concentric mates, etc.

RENDERING

Rendering of the Solid works model is done using Photoview 360 and solidworks visualize.

• Photoview 360 is a visualization and rendering solutions, providing interactive environment for viewing designs as well as for creating photo – realistic renderings. It can be used to showcase our designs.
• Solidworks Visualize provides0 quick and easy, professional photo quality images. We can say Solidworks Visualize is Camera for our CAD data.Solidworks visualization provides the right combination of quality, speed, and ease of use and is the best render.

Conclusion

Thus the project design , assembly and Photo Realistic Rendering of American Predator Yatch modelled successfully.
