Radar Mast & Final Assembly of Yacht
Modelling of Sunseeker Predator Yacht on Solidworks
Introduction:
In this course, we learned about complete designing of Sunseeker Predator Yacht using solidworks, from the initial sketching to the final assembling. With the help of appropriate dimensions, sketching of all the parts were done and created separately. Once every part is created, then we assemble the parts into a complete model. After assembling the parts, addition of decals, lights and camera etc. is done to do the rendering of the Sunseeker Predator Yacht using Solidworks visualize.
The parts or the components we created to make the Sunseeker Predator Yacht are:
- Hull.
- Propeller.
- Radar.
- Front Seat.
- Middle Seat.
- Rear Seat.
- Garage Door.
- Radarmast.
- Superstructure.
Objectives:
- To Sketch the parts of Sunseeker Predator Yacht using solidworks.
- To Assemble all the parts to make a complete model in solidworks.
- To add decals and to set camera and lights to get a realistic view of our model.
- To render the model using various features available in the Solidworks visualize.
Design Approach:
There are two types of design approach we follow in designing.
Bottom-up approach
Top-down approach
Bottom-up approach: In the bottom-up approach, the most primitive operation is done first followed by the complex operations.
Top-down approach: The approach in which the design is started at highest possible level and the sublevels are followed by it.

We have,
- Extruded Boss/Base

- Revolved Surface
- Loft Boundary

Extruded Boss/Base:
Extruded boss/base feature is used to make a sketch into a complete solid model or part. This feature contains option such as “From to Direction” to select the direction in which we want to extrude our part. “Dimension” column to get the required the length of our model.

Fig. 03: Model after applying Extrude Boss/Base feature.
Revolved Boss/Base:
To get a cylindrical object, we use Revolved Boss/Base feature in our fully defined sketch. As in Extruded Boss/Base feature we got “Axis of Revolution” to give the axis or plane in which we wish our model to revolve. We also got the direction tab to give the direction for our model.

Extruded Cut:
If we want a hollow space in our model, we can do it by using the Extruded cut feature. This feature requires a proper fully defined sketch with closed entities. When we click on this feature, the property manager window will pop-up with an option similar to Extruded boss/base feature. It got “From and To” to give the feature from where it has to cut our model. And the direction in which it has to cut is given in the “Direction” section available.

Extruded surface:
Extruded Surface feature is used to create an extruded surface of the sketch. Unlike Extruded Boss/Base, Extruded surface feature creates a surface which is not a closed one.

Fillet:
Fillets are the most important and frequently used features in making a model as it has got many advantages. Once we made a solid part, it will have sharp corners and edges which we do not like to have. So, to make the sharp edges/corners to look smooth and have nice finish, we use this “Fillet” feature. The thickness of the fillet can be adjusted in the property manager window pop-up.

Fig. 11: Model after applying fillet feature.
Linear Pattern:
Linear pattern is used make a copies/duplicates of the feature which we want in our model, in the linear direction. It is an easy feature which let us do same the process for n number of times, without adding any extra sketches.
Fig 12: Model before linear pattern is applied.
Fig. 13: Model after linear pattern is applied.
Mirror:
Mirror feature is used to mirror/copy the object, features in our model. When the feature is applied the property manager window will pop-up asking you the axis or plane in which you want your feature or object to get mirrored or copied. You can also select multiple features.
Fig. 14: Model after Mirror feature is applied.
Fig. 15: Model after Mirror feature is applied.
Reference Geometry:
It is used to define a sketch or feature in an appropriate plane or axis. It is also used create a plane of our desired requirement to create a sketch on that plane and then get our model in desired position.

Knit:
Knit is a feature which is used to bind/combine two or more faces and surfaces into a single body. It creates a closed body by filling or closing the gaps in between the edges.
Fig. 17: Model before applying the Knit feature.
Fig. 18: Model after applying the Knit feature.
Mates:
Mates is the feature which you can see and use during the assembly of our parts into complete model. It creates a geometric relationship between two parts. When we apply mate, it defines linear or rotational motion to the parts to get it fixed at the right position with the other part. There are many mates which we can apply to the models, they are:
Coincident mate: coincident mate allows us to make two planes into coplanar. When we apply this mate, the part cannot be removed separate from the plane.
Tangent mate: Tangent mate is used to place the part and the plane in a tangent relation.
Concentric mate: Concentric mate is used to make the circular faces to be concentric and allow them to move along the axis.
Angular mate: Angular mate is allowed to make the part to be fixed at a certain angle with the flat surface.

Assembly of the Chopper:
All the parts that are modelled using Solidworks, has been imported to assembly window in solidworks to assemble them. In assembly, mate is the feature which is most commonly used to locate and relate the parts with one another.
Hull is acts as the main component which is inserted and then fixed, at first. The other components are brought in and then inserted one by one by using planes for reference and giving them proper definition using mate feature once the parts are placed. Some parts are modified during assembly to make it perfect according to requirement.
Decals:
A decal consists of a picture, image, pattern, or design that’s printed on a metal body. We have added decals on Hull surface, Jacuzzi stairs. It gives nice appearance to the yacht.
Rendering:
Rendering is the term used to refer the artistic drawing, how it will look in the future or how the output will look like. Rendering of our Sunseeker Predator Yacht model is done in the SOLIDWORK Visualize software. By using PHOTOVIEW 360, we can add various camera views to the model, we can set various angles, direction, and can set appropriate distance to get the perfect camera view. In SOLIDWORK Visualize software, we can change the color of chopper parts, background, brightness, rotation and various settings of predator yacht. By adjusting the resolution and setting number of passes, we get more detail visuals of the yacht. Rendering is done to check how our predator yacht model will look in the environment.
Conclusion:
Thus, the modeling of Sunseeker Predator Yacht is completed using Solidworks and the rendering of the same is done in Solidworks Visualize.
