Question 1: Describe the difference between solid and hollow 3D forms. Why might an artist choose one over the other?

Answer: Solid forms are completely filled with material, giving a heavy and substantial appearance, while hollow forms have empty space inside, making them lighter and often more delicate. An artist might choose solid forms for strength and stability, or hollow forms to reduce weight and material costs.

Question 2: List three different materials that can be used in 3D design and explain one advantage of each.

Answer: Wood: easily carved and shaped, affordable. Clay: flexible and ideal for detailed sculpting. Metal: durable and strong, suitable for structural work.

Question 3: Explain what is meant by 'mass' in 3D art and why it is important.

Answer: Mass refers to the physical bulk or weight of a 3D object. It is important because it gives the sculpture or model a sense of solidity and presence.

Question 4: Describe how light and shadow can be used to make a 3D object appear more realistic.

Answer: Light and shadow create contrast on the surface of the object, highlighting its form and contours. Proper shading can give the illusion of depth and volume, making the object appear more three-dimensional.

Question 5: Sketch a simple 3D shape such as a cube or cylinder in the space provided. Label the edges and faces clearly.

Answer: A correct sketch would show a 3D cube or cylinder with visible edges, with the faces or sides properly proportioned. Labels should identify the edges and faces, demonstrating understanding of basic 3D forms.

Question 6: Draw a design for a small sculpture that could be made from wire and clay. Include details like how the wire supports the shape and where the clay will be added.

Answer: A good sketch would depict a wire framework with curved or straight supports, with clay applied over or around the wire to create a finished form. The drawing should show the relationship between the wire and clay parts clearly.

Question 7: What is perspective in 3D design, and how can it be used to improve a sculpture or model?

Answer: Perspective involves representing objects in a way that shows depth and spatial relationships. It helps make sculptures and models appear more realistic and proportionate to viewers.

Question 8: Describe two different ways to join or assemble parts of a 3D model or sculpture.

Answer: Using glue or adhesive for attachment; or using mechanical fasteners such as screws or nails. Other methods include welding or interlocking parts.

Question 9: Sketch a packaging design for a small 3D printed model, including the shape of the box and any labels or decorations.

Answer: A clear sketch would show the box shape, details like flaps or tabs, and space for labels or decorative elements. Perspective and proportion should be considered.

Question 10: Explain why understanding the properties of different materials is important when designing 3D objects.

Answer: Different materials have unique strengths, flexibility, weight, and appearance. Knowing these helps designers choose suitable materials for durability, aesthetics, and functionality.

Question 11: Identify two safety precautions to take when working with tools and materials in 3D design projects.

Answer: Wearing protective gloves and goggles to prevent injuries; ensuring tools are used properly and kept in good condition.
