3D Modeling EXERCISE 1: MODELING FROM PRIMITIVES OBJECTS
EXERCISE 1: MODELING FROM PRIMITIVES OBJECTS
Homework requirements link
1. Interface Layout and Navigation:
• Blender’s interface includes multiple windows (like 3D View, Timeline, Properties Panel, etc.). Beginners need to understand the functions of each area and how to switch between them.
• Learn basic view navigation: such as rotating the view with the middle mouse button, zooming with the scroll wheel, and panning the view with Shift + middle mouse button.
2. Basic Operations and Shortcuts:
• Familiarize yourself with basic Blender shortcuts (e.g., G: move, R: rotate, S: scale, E: extrude, Tab: toggle edit mode).
• Learn how to select objects, with right-click or left-click selection (Blender has an option to switch the default selection method).
3. 3D Modeling Creation and Editing:
• Learn how to add basic geometries (such as cubes, spheres, cylinders, etc.).
• Master entering edit mode for detailed editing, and manipulating basic elements like vertices, edges, and faces.
• Learn modeling techniques like extrusion, loop cuts, and subdivision surfaces.
4. Materials and Textures:
• Understand how to apply materials to models and learn how to use Blender’s shading system.
• Learn how to add textures and master UV unwrapping (mapping 3D surfaces to 2D texture images).
5. Lighting and Camera:
• Learn how to add lights to your scene and adjust their type, intensity, and color.
• Learn how to set camera positions and angles, and how to render appropriate views.
6. Animation and Keyframes:
• Understand basic animation concepts, learn how to set keyframes for simple object animations.
• Learn how to use the Timeline, Graph Editor, and Dope Sheet to control animations.
7. Render Settings:
• Learn how to set render parameters, choose the render engine (like Cycles or EEVEE).
• Understand how parameters like resolution and sample rate in render settings affect the final image quality.
8. Common Plugins and Extensions:
• Blender has many plugins to use, and beginners can try some commonly used ones to enhance workflow, like layout and interface customization, automated modeling tools, etc.
9. Saving and Exporting:
• Learn how to save Blender project files (.blend), and how to export works to other formats (like .obj, .fbx, .stl, etc.).
🤩 Course content: This class conducted practical exercises, with the main assignment being to independently create a 3D table. The teacher explained to us the different application methods of interface options, such as creating shapes for adjusting length, width, and height, as well as the correct use of X，Y，Z axes.
We will first pull out a rectangular model and adjust its flattened state. The table legs can be replicated to maintain consistency, and the position can be adjusted by dragging the center axis. Observe the rationality in the top view, front view test diagram, and partial view.

Reflection
When I first encountered 3D modeling, I felt completely lost. Facing an entirely unfamiliar software interface, the various tools and functions seemed overwhelming, and every step required time to understand and explore. Switching perspectives, editing vertices, applying materials—these seemingly professional terms left me unsure where to begin.
When I first tried modeling, even simple geometric operations could take me hours, especially when mistakes in the details required starting over. Although the process was often frustrating, the sense of achievement and satisfaction that came with completing a small project made me realize how important patience and attention to detail are in learning 3D modeling.
At the same time, I came to deeply understand that 3D modeling is not just a technical skill—it’s a creative process that combines art, logic, and spatial awareness. While there’s still much to learn, I believe that with persistence, the feeling of confusion will eventually be replaced by proficiency and confidence. In the future, I’ll be able to use modeling to express my own ideas and creativity.
