Study Notes

3D Component Modelling: Model 3

Aim: To create a 3D model of a custom-shaped component using a parametric modelling software.
Software: SOLIDWORKS
Requirements:
- Parametric Modelling Software (Solidworks)
- Computer System with specific requirements: 250GB hard disk, 8GB RAM, 4GHz processor, 2GB graphics card, Monitor, Keyboard, and Mouse
- Laser printer or Plotter
Procedure:
- Start SOLIDWORKS
- Select Part to create a new document
- Configure SOLIDWORKS options
  - System options > Sketch> Relations/Snaps > Check Automatic relations
  - Document Properties > Units > Unit system - MMGS (millimeter, gram, second) and Decimals - None
- Extrude Boss/Base:
  - Select Right Plane for orientation
  - Draw the sketch as shown in Fig.A3.1 using Line, Rectangle, Circle, and Offset Entities.
  - Apply relations: F, Horizontal, Vertical, Collinear, and Equal.
  - Modify dimensions using Smart Dimension
  - Remove unwanted lines using Trim Entities
  - Create fillets (R12 and R14) as shown in Fig.A3.2
  - Exit Sketch
  - Set Depth to 82mm in Extrude PropertyManager
- Rotate view to Isometric
- Create a reference plane parallel to Face 1 at a distance of 41mm:
  - Select Plane tool
  - In Property Manager, select Face 1 as First Reference
  - Click Flip Offset and set offset distance to 41mm
- Select Plane - 1 and orient it Normal to
- Extrude Boss/Base on Plane - 1
  - Draw sketch as shown in Fig.A3.5 using Line and Sketch Fillet
  - Modify dimensions using Smart Dimension
  - Exit Sketch
  - Set Direction 1 to Mid Plane and Depth to 12mm in Extrude PropertyManager
- Rotate view to Isometric
- Create a cut-out using Extruded Cut:
  - Select Face-2 and orient it Normal to
  - Draw two circles as shown in Fig.A3.7 using Circle tool.
  - Modify dimensions using Smart Dimension
  - Exit Sketch
  - Set Depth to 106mm in Cut-Extrude PropertyManager
- Rotate view to Isometric
- Create fillets with a Radius of 12mm on edges 1, 2, 3, and 4.
- Combine bodies using Combine tool
- Dimension the model using Smart Dimension
- Change appearance (colour) using Edit Appearance tool
- Final result: The final model will be as shown in Fig.A3.9.

3D Modeling Tools

Cut: A tool within 3D modeling software used to create an incision or opening within a model.
Depth: The setting that controls how far into the model the cut extends.
Combine Bodies: A tool used in CAD software to merge multiple individual bodies into a single, unified object.
Isometric View: Provides a three-dimensional perspective of the model, aiding in visualization and understanding of its spatial relationships.
Reference Plane: A flat surface used in 3D modeling as a reference point for creating features and dimensions.
Sketching Process: Involves creating 2D shapes and curves that form the foundation for 3D features.
SolidWorks: A prominent 3D CAD software known for its features and applications in product design.
Unit System: Refers to the measurement units (e.g., millimeters, inches) used within the software file.
Extrusion: A 3D modeling feature that extends a 2D shape along a specified direction to create a solid volume.
Relations: Constraints used in sketching to define relationships between geometric entities.
Viewport: Window within the CAD software that allows for viewing and interacting with the model from different angles.
Rotation Axis: The imaginary line about which an object rotates.

SolidWorks

SolidWorks uses MMGS (Millimeters, Grams, Seconds) as its default unit system.
The Right Plane is a default plane in SolidWorks, which can be used to create a sketch by using the Sketch command.
You can apply relations during sketching to define constraints between geometric elements, establishing specific relationships between them.
By default, the depth for the first extrusion in SolidWorks is set to 10 mm.

CAD Operations

Offset: A tool used to create a new entity parallel to an existing one.
Fillet: A tool to create rounded corners or edges, as in the provided example with a radius of 14 mm.
Mirroring: Involves creating a symmetrical copy of an existing object.

General CAD Concepts

Reference Plane: Use in 3D modeling plays a critical role in creating features and establishing the spatial positioning of objects.
It is possible in CAD software to view the model in 2D, allowing you to explore the model from specific planar perspectives.
It is not necessary to create a sketch before applying a feature in SolidWorks.
The sketch process does not include "Modifying Dimensions after the sketch creation", as this is done after the design is complete.
The distance from Face -1 to Reference Plane - 1 can be directly measured within the software to obtain the precise value.
The first step in starting a project in SolidWorks is to create a new file.
