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

Answer: A solid 3D form is fully filled with material and has no hollow spaces inside, such as a cube or sphere. A hollow 3D form has a shell or empty space inside, like a paper lantern or a hollow sphere.

Question 2: Explain what is meant by 'mass' in 3D design and why it is important.

Answer: Mass refers to the perceived weight or solidity of a 3D object. It is important because it affects how the object looks and feels, giving it realism or visual weight in a design.

Question 3: List three different materials that can be used in 3D design and briefly describe their suitability for different projects.

Answer: Wood - suitable for sturdy, functional objects; Clay - ideal for detailed sculptures; Cardboard - good for quick, lightweight models.

Question 4: Outline the purpose of using shading and texture in creating the illusion of depth in 3D artwork.

Answer: Shading and texture help simulate light and surface quality, making flat drawings appear three-dimensional and more realistic by indicating light, shadow, and material surface.

Question 5: Describe what a 'wireframe' model is in 3D design and its typical use.

Answer: A wireframe model is a skeletal outline of a 3D object made of lines, used to plan or visualize the shape before adding surfaces or details.

Question 6: Sketch a simple 3D geometric shape, such as a cube or cylinder, showing different sides and angles.

Answer: A correct sketch should clearly show multiple sides of the shape with lines indicating depth, perspective, and proper proportions.

Question 7: Design and sketch a small sculpture concept, incorporating interesting shapes and textures.

Answer: A successful sketch will include a variety of forms, surfaces, and textures, demonstrating an understanding of volume and spatial relationship.

Question 8: Explain the importance of scale and proportion when designing 3D objects.

Answer: Scale and proportion ensure that different parts of a 3D object are correctly sized relative to each other, making the object look realistic and balanced.

Question 9: Identify two common tools used in constructing physical 3D models and describe their function.

Answer: A craft knife is used for cutting materials accurately, and glue is used to join different parts together securely.

Question 10: Describe how light and shadow can be used to enhance the three-dimensional appearance of a sculpture or model.

Answer: Light and shadow create contrast on surfaces, highlighting contours and depth, making the object appear more three-dimensional and realistic.
