1. Objective
The objective of this stage is to build a solid foundation in 3D modeling using the Extrude and Revolve features in SolidWorks. This study focuses on converting 2D sketches into precise 3D geometries, understanding the geometric logic behind each tool, and applying these features to create components with real mechanical and engineering value under the guidance of our supervising teacher.
2. Summary of Learning
During this research stage, our team learned how to transform 2D sketches into detailed 3D models using the Extrude and Revolve commands.
- The Extrude feature allows sketches to extend along a specified direction, generating solid bodies such as blocks, plates, or brackets. It provides full control over extrusion depth, direction, and end conditions to achieve precise geometry.
- The Revolve feature creates rotationally symmetric parts by revolving a sketch around a defined axis—ideal for designing circular or conical components like bottles, pulleys, shafts, and pipes.
Through multiple practice exercises, our team developed a deeper understanding of sketch preparation, geometric constraints, and feature combination to form accurate models. These activities significantly enhanced our spatial visualization and comprehension of how 2D geometry evolves into complex 3D structures.
3. Application to Water Purifier Design
In the Eco Filter Project, we applied these modeling tools to create key components of the portable water purifier:
- Extrude was used to construct the main body, base plates, and filter casings with precise wall thicknesses.
- Revolve was used to form cylindrical and conical parts such as filter housings and pipe connectors.
Using these features ensured consistency, dimensional accuracy, and realistic mechanical fitting between components. This stage also laid the groundwork for future assembly and motion simulation processes by producing structurally sound 3D parts ready for integration.
4. Conclusion
This stage established our team’s essential 3D modeling skills in SolidWorks through the use of Extrude and Revolve. By mastering these core tools, we gained a clearer understanding of how 2D sketches develop into mechanical components and how these operations serve as the foundation for advanced design. The process strengthened our precision, spatial reasoning, and confidence in digital modeling—key abilities for developing efficient and reliable engineering products.
5. Next Step
In the next phase, our team will explore Cut Extrude, Fillet, and Chamfer tools to refine part details, enhance functionality, and improve aesthetics before proceeding to the assembly stage of the purifier model.
