                                                                             MODELING, ASSEMBLY AND PHOTO REALISTIC RENDERING OF YACHT

 

1) OBJECTIVE

• To design the individual parts of Yacht with required dimensions in SOLIDWORKS.
• To carryout assembly of designed parts using suitable relations of all part models in SOLIDWORKS.
• To add Decals, Lights, Camera, Appearance and start rendering the assembled model.
• Apply Photoview 360 and SOLIDWORKS Visualize rendering tools, and obtain realistic view of the model.

 

2) INTRODUCTION

SOLIDWORKS is a CAD modeling software which is used for solid and surface designing various parts. Here with the help of commands we draw the sketches of individual parts of yacht using the given dimensions. Convert those 2D sketches to 3D model in solidworks. After designing all individual parts we carryout assembly of the yacht. Next step is to add decals, lights, camera and do rendering in solidworks. To get the realistic view of the designed model we use Photoview 360 and SOLIDWORKS Visualize rendering tools. Here we add suitable environment, backplates, appearance and set the image quality for getting realistic view.

The various parts of Yacht are as follows:

• Propeller
• Radar
• Hull
• Garage Door
• Rear Seat
• Front Seat
• Middle Seat
• Superstructure
• Radar Mast

3) DESIGN METHODOLOGY

In this project we used bottom-up approach : First we design the individual components and then assemble all the components to make a complete product.

4) FEATURES

 

Let us discuss the features which are used while designing the individual components of Yacht.

Extruded Boss

 It is the basic feature in SOLIDWORKS. To use this feature, first we need to do a fully defined 2D sketch and

then convert the 2D sketch into a solid body. After choosing the extruded boss option a property manager

window pops-up. Here we add dimensions in the required directions and also we need to choose the start

and end point of the feature. Blind, midplane, from the vertex are some of the available options to use.

 

Fillet

 Some of the 3D shapes have sharp edges which need to be given smoothness. For this purpose we add fillets.

By using this feature the edges get some roundness with appropriate radius. By this we can delete the unwanted

material from the solid body and give it a nice appearance. Constant size, variable size, face and full round fillets

are the types of fillets used.

                                                                                                                                             

Revolved Boss

It is used to create solid 3D model around an axis. The sketch can be revolved around an axis to add materials

to it. Hollow cylinders, hollow spheres, solid spheres can be created using this feature. We need to select the

axis of rotation and give it a direction to come into existence.

Extrude Cut

     

Extrude cut feature removes materials from the part. We can use this tool by projecting a sketched section

Normal to the sketching plane. Both open and closed sections can be used to create a cut. Removing material

using a closed section creates a slot.

Shell

The shell feature hollows out a part, leaves open faces which are selected, and creates thin walled features on

the remaining faces. To create a closed, hollow model we need to simply do not select any face on the model. 

Linear and circular pattern

 Linear patterns are used to create multiple instances of one or more featues that can be spaced uniformly along

one or two linear paths.

Circular patterns are used to create multiple instances of one or more features that can be spaced uniformly

around an axis.

Mirror

 Creates a copy of a feature mirrored about a face or a plane. Select the feature or the faces that comprise the

feature. Bodies to mirror. Select a body in a single model or multibody part to create a mirror entity. This gives

a symmetrical part without really drawing a sketch of it.

                                             

Projected Curve

 The project curve feature is to create a 3D curve. We can create multiple closed or open contour projected curves

from a single sketch. Create two 2D curves using spline tool on different planes and the project a 3D curve.

The resulting yellow color curve is the projected ones.

Chamfer

 The chamfer tool creates a beveled feature on the selected edges, faces, or a vertex. Angle-distance, Distance-

Distance, Vertex, Offset-face and face-face are the types of chamfers.

 

               

Sweep

 This feature helps sweep a closed profile along a closed or open path.

                     

Mate

 Mate creates geometric relationship between assembly and component. When we add mates, it defines the

allowable direction of linear or rotational motion of component within its degree of freedom, visualizing the

assembly’s behaviour.

The feature includes:

• Coincident mate
• Concentric mate
• Tangent
• Angular mate

 

 

Offset

 Creates concentric circles, parallel lines, and parallel curves. We can offset an object at a specified distance or through a point.

Offset entities takes a copy of an existing geometry and copies it at an offset.

         

 

Spiral/Helix

Spiral curve is used as guide curve for sweep feature.

It can be of constant pitch or variable pitch.

        

 Surface Extrude

After drawing a fully defined 2-D sketch, in reference with that sketch we can extrude surfaces to surrounding features in both the directions.

      

 Surface Trim

Using a plane or a sketch (2-D, 3-D) as a trim tool we can trim the unwanted surfaces.

We can also keep the surfaces to be considered by this feature.

 Surface Extend

We can extend any surface by selecting an edge or a face.

In this feature edges or faces can be extended upto certain distance, upto any point or upto any surface.

 

Surface Sweep

By selecting any face, edge or a curve as sweep profiles. Profile may be open or closed for this feature.

Selecting any sketch as a path we can create surface sweep. The start point of the path must lie on the plane of the profile.

Surface Offset

This is the advanced feature to offset the entities. Just selecting surface offset and choosing the faces

as parameters we can create offset sketch of surfaces.

 

Surface Knit

This tool is to combine two or more surfaces into single entity. With this feature we can convert two or more

entities into single entity and make it a solid part.  Here knitting tolerance can also be altered to control the

gaps between the entities.

Ruled Surface

Using this feature we can create surface which extends to specified direction.

It may be of tangent to surface, normal to surface, tapered to vector and so on.

Surface Loft

Surface loft helps to create complex geometry in a single feature. It creates surface between cross-sections of the model. Faces, edges,sketches can be considered as loft profiles.

 

Dome

This feature helps to create a bulged surface at the end of any portion. Eliptical dome can also be applied.

Combine

This feature helps to combine two or more parts of a model to form a single entity.

There are three types in it add, subtract and common. One can add or subtract bodies, or keep material

That is common to the selected bodies.

 Reference Plane

It includes edges, planes, axes, points to create a plane. Using this reference plane we can create sketches

That are used in lofts, sweeps, patterns etc.

 

5) MODELING PARTS

Following are the parts of YACHT :

Blueprint Setup

The first step in modeling the yacht is to setup the blueprint. For this go to tools, sketch tools and sketch picture.

Browse the picture that is to be adjusted in particular plane. By this applying all views picture on appropriate

planes we get blueprint setup to proceed further.

Propeller

It is a mechanical device for propelling a boat, consisting of a revolving shaft with two or more broad, angled

blades attached to it.

Radar

It is located at the top of the model to detect the presence, direction and objects by sending out pulses of radio waves which are reflected off the object back to the source.

Hull

The main body of a yacht including the bottom, sides, and deck but not the masts, superstructure, engines and other fittings. It acts like protective portion for goods, machinery from natural calamity.

Garage Door

Garage door is located at the back portion of the model used to protect the vehicles parked in the garage.

Rear Seat

It is located at the rear side of the yacht.

Front Seat

Front seat is located at the front part of the model. It is basically mounted at the front of the superstructure.

Middle Seat

Middle seat is located at the middle portion of the model.

Superstructure

It is the part which consists navigation controls, front seat and pool. It is mounted at the top surface of the hull to give the model a proper shape of a yacht.

Radar Mast

This is an electronic navigation instrument which uses a rotating antenna to sweep a narrow beam of microwaves around the water surface surrounding the yacht.

6) ASSEMBLY

• Now that we have designed all the individual components of the Yacht , we need to assemble them by creating a new assembly file, importing all the parts which are fully modelled.
• In assembly, mate feature is most commonly used to locate and relate the parts with one another.
• Standard mates include angle, coincident, concentric, distance, lock, parallel, perpendicular and tangent mates. Advance mates include limit, linear, path and width mates.
• Hull is the main component which is inserted first. The other components are inserted one by one. By using planes for reference and giving the mate feature once the part gets fixed it floats with the main frame.
• Some parts need to be modified during assembly to make it look accurate.

 

7) PHOTO REALISTIC RENDERING

 

• In this project we use Photoview 360 and SOLIDWORKS Visualize rendering tools, and obtain realistic view of the model.
• PhotoView 360 is a SOLIDWORKS add-in that produces photo-realistic renderings of SOLIDWORKS models. The rendered image incorporates the appearances, lighting, scene, and decals included with the model.
• SOLIDWORKS Visualize is the fastest and easiest way to produce photo quality images by bringing in the YACHT model. It generates photo quality image, interactive animations, and 360 degree spin to effectively communicate the most complex design details.
• In this we can set scenes, backplates, environment, lights and cameras to get the realistic view and obtain the rendered images.

 8) CONCLUSION

• All the individual parts of yacht are modelled and assembled using SOLIDWORKS.
• The assembled model is rendered and with the help of PHOTOVIEW 360 and SOLIDWORKS Visualize realistic views of Yacht are obtained.
