Question 1: Describe the difference between a solid form and a hollow form in 3D design. Provide an example of each.

Answer: A solid form is a shape that is fully filled with material, like a clay sphere. A hollow form has an empty space inside, like a paper lantern. The key difference is whether the interior is filled or empty.

Question 2: Sketch a simple geometric 3D shape, such as a cube or sphere, in the space provided. Label the basic parts, such as edges or curves.

Answer: A correct sketch would show a clear three-dimensional shape with visible edges or curves, demonstrating understanding of form. Labels should include 'edges' for a cube or 'surface' for a sphere.

Question 3: Explain the technique of shading used to create the illusion of depth on a 3D object. Mention at least two shading methods.

Answer: Shading creates the illusion of depth by varying light and dark areas. Methods include gradient shading, where tones gradually change, and hatching, using parallel lines to build up shadow.

Question 4: Identify and describe three different materials commonly used in 3D design projects.

Answer: Common materials include clay, which is malleable; paper or card, which is lightweight and easy to cut; and wire, which is flexible and used for armatures or frameworks.

Question 5: Describe the process of creating a basic armature for a small sculpture. What materials might you use?

Answer: Creating an armature involves constructing a supportive framework to hold the sculpture's shape. Materials such as wire or thin metal rods are bent and joined to form the basic skeleton.

Question 6: Sketch a design for a small, functional container such as a box or cup. Include details like opening, sides, and base.

Answer: A correct sketch would show the container with a clear opening, four sides, and a base. The lines should suggest three-dimensionality, with perspective if possible.

Question 7: Explain how scale and proportion are important in 3D design. Provide an example where incorrect scale affects the design.

Answer: Scale and proportion determine the size relationships between parts of a design. For example, a tiny handle on a large sculpture might look out of place and affect usability or aesthetic balance.

Question 8: Draw a design for a decorative stand that could hold a small object. Think about stability and visual balance.

Answer: A well-drawn design would include a stable base, supportive sides or structure, and an aesthetic appearance. The sketch should show consideration of balance and function.

Question 9: Describe the technique of joining parts in 3D modeling. List two methods and when they might be used.

Answer: Joining parts can be done via gluing, which is suitable for materials like paper or clay, or welding, used for metal components in more durable models. Both create a secure connection.

Question 10: Sketch a simple model of a wearable item, such as a bracelet or pendant. Indicate how it might be assembled or constructed.

Answer: The sketch should depict the shape of the item, with details like a clasp or opening. It should suggest how parts are connected or assembled, such as linking or fitting together.

Question 11: Explain the importance of surface texture in 3D design. How can texture affect the overall appearance and feel of a piece?

Answer: Surface texture adds visual interest and can influence how a piece feels to touch. Rough textures may suggest age or rustic quality, while smooth surfaces can look polished and modern.
