My CAD Learning Journey

Introduction to CAD & Basic Modeling

I began by exploring the foundational concepts of Computer-Aided Design. I learned about the importance of CAD in engineering and design and the key differences between 2D and 3D CAD. I also became familiar with the workspace of popular software like **AutoCAD** and **SolidWorks**, and practiced using basic drawing commands such as Line, Circle, and Rectangle to create initial shapes.

Sketching and Basic Features

With a grasp of the basics, I dove deeper into creating models. I learned to create and manage sketches, and the critical role of using **constraints** to precisely define geometry. I then transformed these 2D sketches into 3D objects using features like **Extrude**, **Revolve**, and **Sweep**. I also learned how to refine my models using modifiers like **Fillet**, **Chamfer**, and **Shell** and how to use the feature tree to manage my design history.

Dimensions & Annotations

Today was all about making my designs understandable for manufacturing. I focused on adding accurate dimensions and annotations to my drawings. This included linear, angular, and radial dimensions, as well as text annotations for labeling parts. I also learned about using leaders and hatching to create clear and professional documentation, adhering to proper drawing standards like units and scale.

Advanced 2D CAD Techniques

I returned to 2D CAD to learn advanced techniques for creating more complex geometry. I worked with **polylines** and **splines** to create intricate curves and organic shapes. I also mastered essential modification tools like **Trim**, **Extend**, and **Offset**. A key learning was using **Blocks** to create reusable components, and utilizing layouts and paper space for professional print outputs.

Introduction to 3D CAD

I took the big leap from 2D to 3D. I learned the fundamental differences in workflow and thinking, and how to navigate the 3D workspace. I practiced creating my first true 3D objects using tools like **Extrude**, **Revolve**, **Loft**, and **Sweep**. I also gained a solid understanding of 3D coordinates, axes, and planes, which are essential for precise positioning and modeling in a three-dimensional space.

3D Modeling Techniques

Building on my 3D skills, I learned how to modify and manipulate my models in new ways. I practiced using **Move**, **Rotate**, and **Scale** to position and resize objects. A key part of this day was mastering boolean operations like **Union**, **Subtract**, and **Intersect** to combine or cut parts. I also applied **Fillet** and **Chamfer** in 3D, and got a first look at creating **assemblies** by combining multiple components.

Rendering & Visualization

To finish my first week, I focused on creating professional-grade presentations of my work. I learned how to apply realistic materials and textures to my models, set up proper lighting, and configure camera angles to produce stunning, photorealistic renders. This process transforms a technical CAD model into a visually appealing image for portfolios and presentations, bringing my designs to life.
