Radar Mast & Final Assembly of Yacht

Title: Design of Sunseeker Yatch.

Objective:

The objective of this project is to learn and understand the different tools and commands in SolidWorks by creating a Model of the Sunseeker Yatch with all the different parts and to assemble the different parts in the assembly. Finally to Render and make a photorealistic view in the SolidWorks Visualize and PhotoView 360.

Introduction:

In this project we use Solidworks 2020 software to design an Sunseeker Yatch and the complete procedure of creating parts and the assembly is explained in this report.

Features of Solidworks used in this project are:

BASIC FEATURES:

  • Sketch: A collection of lines and other 2D objects/entities on a plane or face that forms the basis for a feature such as a base or a boss. A 3D sketch is non-planar and can be used to guide a sweep or loft.
  • Offset: It is a feature in sketching features, wherein an entity can be placed away from the original entity at a certain distance.
  • Extrude: A feature that projects a sketch to either add material to a part (in a base or boss) or remove material from a part (in a cut or hole).
  • Fillet: Fillet creates a rounded internal or external face on the part. You can fillet all edges of a face, selected sets of faces, selected edges, or edge loops. Fillet can have single radius throughout or it can have multiple radii.
  • Chamfer: A cut on the edge or corner of something that makes it slope slightly rather than being perfectly square. It can either be symmetric or asymmetric.
  • Loft: Loft creates a feature by making transitions between profiles. A loft can be a base, boss, cut, or surface. You create a loft using two or more profiles. Only the first, last, or first and last profiles can be points. All sketch entities, including guide curves and profiles, can be contained in a single 3D sketch.
  • Dome: Select one or more faces. You can apply domes to faces whose centroid lies outside the face. This allows you to apply domes to irregularly shaped contours. Dome can be elliptical or spherical.
  • Split: The Split tool is used to project an entity (sketch, solid, surface, face, plane, or surface spline) onto other surfaces or curved/planar faces. You are also able to split faces on multiple bodies with one command.
  • Trim Entities: Select the trim type based on the entities you want to trim or extend. All trim types are available with 2D sketches and 2D sketches on 3D planes.
  • Revolve: This feature makes a solid body or surface which has circular symmetry around an axis.
  • Dynamic Mirror: Dynamic mirror is an important tool in solid works. As you sketch the entities, they can be mirrored about the pre-selected sketch entity with this tool.
  • Appearances: An appearance defines the visual properties of a model, including color and texture. Appearances do not affect physical properties, which are defined by materials.
  • Combine: Combine is the type of feature available in solid works to manually combine the two bodies which intersect each other.
  • Shell: The shell feature helps create thick, thin, or composite shells from solid bodies. This feature can also create shell which is offset from the solid body.
  • Circular Pattern: The circular parent bodies/ features are used to create a different number of instances of the required feature to create the pattern circularly.
  • Linear Pattern: In linear pattern parent bodies/ features are used to create a different number of instances required to create the pattern linearly along a pre-selected direction.

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.
  • Parts like hull, superstructure, front and rear seat of Sunseeker Yatch are surface modeled.

Features Description:

  • Lofted Surface: Loft Surfaces are surfaces generated by multiple 3D Curves or existing edges creating a smooth tangency between the selected curves.
  • Swept Surfaces: Swept 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 knitis 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
