explore form, function and surface using models, samples, material exploration and technical notes

Three‑Dimensional Design – IGCSE Art & Design 0400

1️⃣ What is 3‑D Design?

Think of a crayon – it’s not just a line, it has volume, weight and a texture. In 3‑D design we explore these qualities to create objects that work and look good.

2️⃣ Exploring Form

Form is the shape of an object. It can be geometric (cube, sphere) or organic (leaf, shell). Use the rule of thirds to balance your form.

• Start with a sketch – draw the silhouette.
• Build a wireframe model to test proportions.
• Adjust symmetry or asymmetry for visual interest.

3️⃣ Function & Purpose

Every object should solve a problem. Ask: What will it do?
Use the design thinking loop: Empathise → Define → Ideate → Prototype → Test.

1. Identify user needs.
2. Sketch multiple solutions.
3. Build a prototype (paper, clay, 3‑D print).
4. Test for ergonomics and durability.

4️⃣ Surface & Texture

Surface is how the object feels and looks. Think of a smooth marble vs. a rough bark. Surface can be painted, glazed, carved or printed.

5️⃣ Models & Samples

Build scale models to test form and function. Use sample swatches to check colour and texture before final production.

• Clay model for shape.
• Cardboard mock‑up for size.
• Material swatch card for colour & finish.

6️⃣ Material Exploration

Different materials behave differently. Use the material chart below to decide what fits your design.

7️⃣ Technical Notes & Sketchbook Tips

Keep a technical sketchbook to record:

1. Dimensions & scale.
2. Material choices.
3. Surface finish notes.
4. Problems & solutions.
