Modelling, assembly and rendering of Yatch

Title: Modelling, Assembly and Rendering of Yatch in solidworks

Objective: To recreate parts of Yatch, assembled them and creating photorealistic rendering of the Assembly.

Introduction: This report is about design and assembly of Sunseeker Yatch in solidworks and rendering the Yatch using photoview 360. Solidworks is a 3D CAD software using which i have modelled the different parts of the Yatch assembled them in proper manner, adjusted Yatch orientation to make it look like real world yatch, then using photoview 360 which is rendering software, I have render the images of Yatch in different views.

Design methodology: For assembly of yatch I have used Bottom up approach in which all the parts are prepare according to dimensions and then assembled.

Top down approach: In the top-down approach, an overview of the system is prepared without going into detail of any part of it. In this approach you start your work in the assembly and built parts to fit in the assembly. Geometry of one part is used to help define the other parts.

Description:

Sketch tools used in this project:

• Sketch: To create a new sketch or edit previous sketch.
• 3D Sketch: To create a new sketch in 3 dimensions.
• Smart Dimensions: Creates dimensions for selected one or more 2d or 3d sketch entities.
• Line, Circle, Spline, Rectangle, Arcs, Ellipse, Slots, Sketch fillet.
• Trim Entities: Used to trim extra sketch entity.
• Extend Entities: Used to extend sketch entity to meet another entity.
• Convert Entities: Converts selected edges and sketch entities into identical entities on sketch plane.
• Offset Entities: Offsets the selected sketch entities by specified distance.
• Mirror Entities: Mirrors the selected sketch entities about centerline or plane reference.
• Linear pattern: This tool patterns the selected sketch in one or two linear direction.
• Circular Pattern: This tool patterns the sketch entities in circular instances.
• Dynamic Mirror: This tool creates sketch entities that are mirror about selected entity as you draw them.

Features used in this Project:

• Extrude Boss/Base: This feature extrudes the selected sketch in one or two directions and creates a solid Feature.
• Revolve Boss/Base: This feature revolves the selected sketch around the selected axis to create a solid feature.

• Delete faces: Delete faces from surface bodies or solid body.
• Extend Surface: Extend one or more edges or faces on surface, based on end conditions and extension type.

Parts:

1) Propeller: a mechanical device for propelling a boat consisting of a revolving shaft with two or more broad, angled blades attached to it. There are 3 propeller in our yatch.

Sketch tools used: line, spline, rectangle, Circle

Features used: Revolve, Loft, Cut extrude, Circular pattern, fillet

2) Radar: It is a precious navigation aid, especially in situations of reduced visibility. It can be used to know the position and distance of other boats, other obstructions such as rocks and buoys and the coast.

Sketch tools used: Line, Circle, Offset entities, Polygon, Text

Features used: Extruded Boss/Base, Cut extrude, Sketch Pattern, Split Line, Fillet, Mirror

3) Blueprint Setup: A blueprint is a reproduction of a technical drawing, documenting an architecture or an engineering design, using a contact print process on light-sensitive sheets.

Tools>Sketch tools> sketch picture feature is used to setup blueprints in different views. Also reference planes are used create additional planes.

4) Hull: The hull of a ship is the most notable structural entity of the ship. It can be defined by that it is the watertight enclosure of the ship, which protects the cargo, machinery, and accommodation spaces of the ship from the weather, flooding, and structural damage. A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top or it may be fully or partially covered with a deck.

Assembly

For assembly of Yatch we have fix Hull as reference for all other parts. In the following order we have assembled all the parts with given mates.

Assembly images:

1)Front view

2) Side view

3) Top view

4) Camera view

5)Isometric view

Features that are used for assembly of Yatch : Insert parts, Mates

Mates:

Creates geometric relationships between assembly components to define the allowable direction of linear or rotational movement of components. We can move a component within its degrees of freedom to visualize the assembly's behavior.

Sr.no	Part	Mates
1	Hull	Fix
2	Superstructure	Coincident, Distance
3	Radarmast	Distance, coincident
4	Front seat	Coincident, Distance
5	Middle seat	Coincident, Distance
6	Rear seat	Coincident, Distance
7	Garage door	Cocentric, Coincident, Limit angle
8	Propeller	Coincident, coincident
9	Radar	Coincident, coincident
10	Chopper bike	Coincident, fix

Rendering

Before rendering of model we have done some preprocessing. This includes applying decals to hull deck surface, stairs etc . After preprocessing we have done camera setup, background and environment conditions, and lights position adjustments. Then using photoview 360 we have done final rendering.

Rendered Images:

Conclusion

• All parts of Yatch are successfully modeled and appropriate appearances are given to each parts.
• The assembly of the parts are done rightly with proper mates and constrains.
• Preprocessing, Camera setup, Light setup, Background and environment setup is done properly.
• Successfully rendered images of Predator using photoview 360.

NOTE: Solidworks visualize is not working in my computer so I have uploaded images rendered in photoview 360.
