Week 2: Computer Aided Design

1. Introduction

During Week 2, the main task was to learn and apply Computer Aided Design (CAD) tools.
We were required to create both 2D sketches and 3D models as part of the assignment.

All of this work was done using Onshape, which is a cloud-based CAD software. It allowed me to design, edit, and visualize my models directly in the browser.

This week is important because CAD skills are essential for designing real-world objects before manufacturing them.

2. Assignment Goals

The requirements for this week were: - Create 2D sketches
- Convert them into 3D models
- Understand basic design workflows
- Prepare designs for real-world use

The goal was not only to draw, but also to think about how the object can be used and built.

3. 2D Sketching in Onshape

I started by creating a 2D sketch in Onshape.

At this stage, I focused on: - Drawing the basic shape
- Defining dimensions
- Making the design accurate

This step is important because the 2D sketch is the foundation of the final model.

Here I will show images of my 2D sketches

4. 3D Modeling Process

After completing the 2D sketch, I converted it into a 3D model.

I used tools such as: - Extrude
- Fillet
- Dimension editing

This helped me transform a flat design into a solid object.

During this process, I learned how to think in three dimensions and understand how shapes are built.

Here I will show images of the 3D modeling process

5. Furniture Plate Design

For this assignment, I designed a plate for furniture that I plan to use in the future.

The idea was to create a simple and practical component that can be used in real furniture construction.

My design includes: - A flat base structure
- Correct dimensions
- A shape that can be manufactured

This project helped me understand how CAD can be used to design useful objects.

Here I will show images of the final design

6. Design Thinking

While working on this project, I also considered: - How the object will be used
- How it can be manufactured
- How stable and strong it is

This shows that CAD is not only about drawing, but also about solving real problems.

7. Challenges and Improvements

During the process, I faced some challenges: - Understanding sketch constraints
- Adjusting dimensions correctly
- Learning tools in Onshape

I solved these by practicing and improving the design step by step.

8. Final Result

At the end, I successfully created a 3D model of a furniture plate.

This model can be used in future projects and can be modified if needed.

Here I will show the final result

9. Conclusion

This week helped me learn the basics of CAD design using Onshape.

I learned: - How to create 2D sketches
- How to convert them into 3D models
- How to design real objects
- How to think about manufacturing

These skills will be useful for future projects.
