Aim:

To create a functional 3D product in Blender, starting from your own sketch idea.

Requirements:

• Paper and pencil for sketching

• Computer with Blender installed

• Mouse for easier control

• (Optional) Reference image of your idea or similar products

Step-by-Step Process

Step 1: Sketch Your Idea

On a piece of paper, draw a simple product idea.
Examples:

• Desk organizer

• Mobile stand

• Mini storage box

• Bookmark holder

• Key hanger

Tips:

• Focus on functionality — What problem does your design solve?

• Add simple dimensions or notes about size.

• Keep the design minimal with basic shapes (no need for perfection).

This step builds design thinking: how your idea will help someone in daily life.

Step 2: Start Blender and Set Up the Workspace

• Open Blender.

• Delete the default cube (select → press X).

• Adjust your view using:

  • Scroll wheel to zoom

  • Middle-click + drag to rotate

  • Shift + middle-click to pan

Understanding navigation is crucial before modeling.

Step 3: Build the Base Shape

• Press Shift + A → Mesh → Cube or Cylinder depending on your sketch.

• Use the Scale Tool (S) to resize.

  • Example: S, Z → stretches vertically

  • S, X or S, Y → resizes horizontally

• For curved objects, use Add → UV Sphere.

Example:
If your idea is a desk organizer, start with a large cube as the base.

Step 4: Add and Combine Parts

• Add smaller shapes for compartments or handles.

  • Example: Add another cube or cylinder.

• To merge them into one solid object:

  • Select both → press Ctrl + J (Join), or

  • Use Modifier → Boolean → Union for cleaner merging.

This simulates how real products are built from multiple joined parts.

Step 5: Refine with Precision

• Use Move (G) and Rotate (R) to adjust parts.

• Activate the Measurement tool (N → Item → Dimensions) to ensure accurate size.

• Check symmetry and proportions — they make products visually balanced.

Optional:
Add cutouts or holes using Boolean Difference (subtract one shape from another).

Step 6: Apply Colors and Materials

• Go to Material Properties → New → Base Color.

• Add textures or finishes (metal, plastic, matte).

• This gives your design a realistic look and helps visualize the final product.

Step 7: Render and Save

• Position your camera (press Numpad 0).

• Add light (Shift + A → Light → Point).

• Go to Render → Render Image (F12).

Save the rendered image (Image → Save As) for your portfolio.
