Assembly of Yacht

YACHT MODELLING

Aim: To model Yacht in Solid works software with available blue prints.

Objective: The objective of this project is to learn the concept of reverse engineering & model the Yacht in the solid works and find out how intricate shapes can be modelled easily in CAD modelling software.

Abstract: Reverse engineering is one of the most powerful techniques applied for most of the sectors such as Automobiles, Aero space industries, Manufacturing industries & R&D to know the existing designs and the possible modifications applied for further development of the product.

The entire modelling process is divided in to Six Stages

1. Blue Print Setup & Creating Planes.
2. Modelling of Hull Part
3. Modelling of Super Structure
4. Modelling of Radar Mast
5. Modelling of front, middle & Rear Seats.
6. Assembling the individual parts.

Step 4: Create the two projection curves using sketch tools.

Step 5: Join them using create 3d sketch option & use surface loft, Surface fill to form the surface bodies.

Step 6: Use above mentioned commands frequently to create a surface bodies and apply the surface knit command to form the solid body

Step 7: use 3d sketches, reference geometry options to create a wipers & extrude cut option to create wind shields

Step 8: After creating surface bodies as per blue prints use surface knit option to form the solid body.

Step 9: Draw a Sketch for creating doors & door handles & apply Fillet where ever applicable.

Step 10: Draw a sketch for railings to create supports as per blue prints.

Step 11: Apply fillets with different values where ever applicable

Step 12: Use Split option & create a surface offset.

Note: The surface Offset is used as reference for modelling of radar mast.

Step 13: draw a sketch for creating the windows.

Step 14: After creating the windows, use Appearance option for applying various colors to the various parts.

Step 15: Save the part as super Structure.

Stage-4
