Radar Mast & Final Assembly of Yacht

MODELLING OF YACHT IN SOLIDWORKS

ABSTRACT

Modelling of Yacht in solidworks.

Modelling of yacht is more purely dependent on the usage of surfacing tools. It requires a complete understanding of the sketch to make over all the sketches for the surfaces of the yacht. The yacht is sectioned into five main structures. They were hull, superstructure, seats (front, middle and rear), propeller and radar mast. In the process of designing the yatch it requires a cruising nature of look, hence surfacing is the best choice for modelling such objects. After surfacing the structures were knitted into one single surface, which enables an enclosed volume. A solid is created from that enclosed volume. Finally the yacht is assembled and then rendered.

SOFTWARE USED

The structures are modelled in the solidworks and then it is rendered in photoview360 and solidworks visualize. Solidworks is a 3d modelling software and it also has add-ins like photview360 and solidworks visualize. The 3d parts are modeled form its 2d sketch.

OBJECTIVES

1. To surface model all the structures and then create the solid model.
2. To apply appearances and decals.
3. To assemble all the structures with the mate constraints.
4. To apply cameras, lights and scenes.
5. To render yatch in photo view 360 and in solidworks visualize.

BRIEF OF TOOLS

1.SKETCH

It is a 2d representation of a 3d part. It includes entities like line, rectangle, spline, circle, etc. It is a predetermined drawing with dimensions and relations.

2. OFFSET

Offset uses selected edges, faces, splines, arcs at specified distance. It saves time by simply reproducing the sketch that we need.

3. EXTRUDE BOSS

A selected closed sketch is extruded to the specified distance which in turn a solid is created.

4. EXTRUDE CUT

A selected closed sketch on a 3d part is deleted or cut from the 3d part for a specified distance or upto next surface etc.

5. FILLET

This is a type of surface continuities which is called G1 continuity. It is also called tangent continuity. It makes the selected faces or surfaces to be tangentially continuous.

6. SKETCH FILLET

It is the fillet given in the 2d sketch itself and making the sketch continuous over the corners.

7. LOFT

It generates surface by creating section profiles in different planes.

8. DOME

Dome is a feature applied to any coplanar or non-coplanar faces which caps them with elliptical or circular profile.

9. SPLIT

After projecting a sketch on a curved face or surface the split tool uses the sketch as trim tool and makes the part to be split. We can removed the selected parts.

10. TRIM

The unwanted projections or sketch entities in 2d sketch are deleted by using this tool.

11. REVOLVE boss/cut

A created sketch can be revolved around an axis to produce a 3d part. Mostly this is useful for producing symmetrical parts. It adds/removes the sketch.

12. DYNAMIC MIRROR

It is used to mirror the sketch entities about the sketch previously created or about any axis.

13. BLOCKS

We can create a 2d sketch and then make block for future use of that sketch in another sketch where it is related.

14. PATTERN

There are linear pattern and circular pattern. It is used to increase the number of instances of the sketch/bodies that have created in a specified direction, which makes the process much easier.

15. COMBINE

This tool combines all the surfaces /bodies/faces into a one single body. All the bodies can be selected as a single body, useful while adding appearances/materials.

16. SHELL

It is used when turning a solid body into a shell body with the specified shell thickness. It is for creating parts like thin cylinders.

17. CHAMFER

It converts the squared edges into a sloped edges.

18. PLANES

This is a very useful tool to add a new plane in a specified direction which is handful for creating sketches in complex faces.

19. MOVE/COPY BODIES

This is used to distance the selected bodies or to copy them.

20. PROJECTED CURVE

This is a curve suspended in 3d world and it is created using 2d sketches from different combination of views like front and top view, top and side view, etc.

21. SWEEP

The 2d sketch it swept along the curve and makes it a 3d part for example lie piping, tubing etc.

22. CONVERT ENTITIES

It is used when we need a direct sketch from a previous one or its projection on the current plane of sketch.

23. COMPOSITE CURVE

This tool combines two or more curves which is obtained from a projected curve.

24. SWEEP SURFACE

A surface is created along desired direction from as section curve.

25. LOFT SURFACE

A surface created by multiple selected edges with tangency.

26. FILLS URFACE

A surface created by selecting the edges which are closed and the curvature has to be adjusted to have a smooth finish.

27. SURFACE TRIM

It is to cut away the materials from the surfaces.

28. KNIT SURFACE

It is more like stitching the clothes. The surfaces are stitched together by adjusting the gaps between them. They can be selected all as a one surface.

29. SWEEP CUT

It removes the material from the 3d part in the direction of the specified curve.

30. BOUNDARY SURFACE

It is used while surfacing a range of curves. It completely uses all the curves in direction 1 and direction 2. It gives a complete c2 continuity from starting to end of curve and also at the side of the curve.

31. RULED SURFACE

It extends the specified surface in desired direction like perpendicular, tangent, normal, tapered to a vector, etc. But it does not result in a continuous surface.

32. FILLED SURFACE

It is like a patch up tool. It can use more than four edges to get filled with a surface.

33. DELETE FACE

This tool deletes the face of solid model.

34. SURFACE EXTEND

This tool extends the surface with only two options like same surface and linear one.

35. THIN EXTRUDE

This feature is to extrude the sketch with the desired thickness.

36 .SURFACE OFFSET

It creates the duplicate surface from existing surface which is useful for making individual structures with the help of duplicate surface as a reference figure.

ASSEMBLY OF YACHT STRUCTURES

In which the assembly is completed by inserting all the individual structures one after another and also constraining them is required. The parts are mated with one another by executing a relation in between them. All required relations are performed to make the assembly fixed. Actually in which the mates are not required for the superstructure, front seat and radar mast because we have our surface offset which automatically finds its mate position and gets fixed, if mates needed we can go for distance mates.

FRONT VIEW OF ASSEMBLY

SIDE VIEW OF ASSEMBLY

ISOMETRIC VIEW OF ASSEMBLY

Features used

1. Inserting components
2. Mates

Mates

Mates are so important while assembly, it decides the relative position of the interlinked parts with one another. There are several mates like parallel, coincident, tangent etc. These mates makes the assembly constraint in all directions.

RENDERING

Rendering is mainly done to have realistic perspective of the developed product, which makes the customer much easier to grasp the intent of the design without knowing its technical detailing, it also makes the product so pleasant with its high in-depth quality of imaging. It enhances the cruising look with high quality resolution rendering.

This can be done by the following ways

1. Photoview360
2. Solidworks visualize

PHOTOVIEW 360

It is an add-inn in solidworks software which is helpful in rendering the yatch structure in solidworks itself. There is preview and final renders available.

It includes the directional lighting from three different direction and having lighting luminosityof 1.1w/srm^2. I made a set of scene proof illumination sheets from which a better look is selected. It has three positional cameras each one illustrates the yatch from different spherical coordinates. The depth of field is focused on the superstructure. A certain magnitude of perspective is added to have realistic look.

CAMERA 1

CAMERA 2

CAMERA 3

SOLIDWORKS VISUALIZE

This results in high quality imaging, an oceanic background can be changed according to the mood board. This gives a highly realistic render results with the apt background scenes and lightings. The rendering is done with quality mode with 500 passes for graphics.

CONCLUSION

Therefore the yacht structures is assembled and it is rendered to have those desired mood board looks.
