Surface modelling of Sunseeker Predator Yacht Using Solidworks
Objective :-
- The objective of this project is used to create a Surface model of different parts of the Yacht using Solidworks
- To assemble the different parts modeled for the Yacht.
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.
Parts to be modeled for Yacht :
The following parts of the Yacht are modeled in Solidworks and assembled together.
- Propeller
- Radar
- Blue Print
- Hull
- Garage Door
- Front Seat
- Middle Seat
- Rear Seat
- Super Structure
- Radar Mast
Some commonly used features across modelling are explained below :
- Loft Surface : Loft Surfaces are surfaces generated by multiple 3D Curves or existing edges creating a smooth tangency between the selected curves.
- Sweep Surfaces : Sweep Surfaces are surfaces that are generated from a section curve positioned along a path.
- Filled Surface : The Filled Surface feature constructs a surface patch with any number of sides, within a boundary defined by existing model edges, sketches, or curves, including composite curves.
- Surface trim : Primarily used to cut away material from a surface, and provides two modes: Standard and Mutual.
- Extend Surface : Extend Surface is used to extend the surface which is already created. There are different options available on the extended surface. We can extend the surface as same surface or we can extend the surface tangent to the surface.
- Surface knit : Surface knit is used to knit the two free edges/open edges of the surfaces together. Also it reduces the gap between the two edges of the surface.
- 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
Where as, - 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.
- Radar :-
Marine radars are X band or S band radars on ships, used to detect other ships and land obstacles.
Features used to create Radar
- Sketch
- Extrude
- Mirror
- Cut Extrude
- Fillet
- Sketch driven pattern
Where as, - Extrude cut : Extrude cut is another cool feature which helps to remove materials from the 3D model.
- Mirror : By using mirror faces with a mid-plane selected only the chosen faces within the revolve will be mirrored
- Sketch pattern : The sketch driven pattern is used to create the replica of the feature, body with reference to some sketch points which are created while creating the sketch itself.
- Split line : The Split Line tool projects an entity (sketch, solid, surface, face, plane, or surface spline) to surfaces, or curved or planar faces. It divides a selected face into multiple separate faces. You can split curves on multiple bodies with one command.
- 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.
Features used to create Hull
- Sketch
- Project Curve
- Swept Surface
- Loft surface
- Extruded surface
- Extend Surface
- Surface Knit
- Extrude
- Mirror
- Cut Extrude
- Fillet
- Pattern
- Split
- Shell
Where as,
- Project curve : The projected curve will be available under the features tab, the project curves command can be used to create a 3d curve. The 3D curve can be created by using the reference of two 2D curves.
- Fill surface : Creates a surface patch within the boundary defined by existing model edges, sketches or curves.
- Surface Extrude : Creates an extruded surface based on some reference sketch.
- Surface Trim : The surface trim is used to trim the surface where one surface interacts with another surface, plane or a sketch.
- Surface extend : Extend the edge, multiple edge or face on a surface based on end condition and extension type.
- Shell : The shell feature is used to create a thickened surface. It can be done either in the interior or exterior surface.
- Chamfer : The chamfer command creates a bevelled feature on the selected edge, face and vertex etc.
- Sweep : The Sweep command is used to create solid features by sweeping a closed profile along an open or closed path.
- Dome : Dome, in architecture, the hemispherical structure evolved from the arch, usually forming a ceiling or roof over the surface/face being selected.
- Helix/Spiral : This command is present under the curves in the features tab. This command actually creates a spiral or helix based on some reference sketch.
- Delete face : This command is used to delete unnecessary faces and this feature comes with some options like, delete face, delete and patch, delete and fill.
- Combine : The combine feature is used to create a single solid body from a number of existing individual solid bodies.
- Garage Door :-
Garage door is used to close the garage part in Hull.

- Ruled Surface : The ruled surface is built by creating a swept surface using selected edges as guide curves.
- Super Structure :-
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.

- Revolve
- Sweep
- Cut Extrude
- Fillet
ASSEMBLY OF YACHT :-
- All the modelled parts are inserted one by one in the assembly.
- Since the parts are created based on the reference with the deck surface the parts are automatically fixed above the deck surface while the part is inserted in the assembly environment.
- So to start the assembly of the yacht the first part being inserted will be the hull which has the deck surface.
- The propeller, radar and garage door are not fully fixed since they have to rotate and move respectively.
- So for these parts, the mates are manually defined to allow them to move in particular axis only.
Below are some of the assembly images of Final yacht are attached, with some changes into appearances.
Conclusion :-
- The parts of the Yacht are modeled.
- The parts are inserted into the assembly environment and the Yacht is assembled.
