Question 1: Name three common manual tools used for drawing and explaining their primary purpose.

Answer: Pencil: for sketching and shading. Ruler: for drawing straight lines. Eraser: for correcting mistakes or lightening areas.

Question 2: Describe the function of a compass in manual drawing. Why is it important?

Answer: A compass is used to draw precise circles and arcs. It is important because it ensures accuracy and consistency in circular shapes.

Question 3: Explain the difference between a craft knife and a scalpel. In what situations might each be used?

Answer: A craft knife is a versatile cutting tool used in general craft work, while a scalpel is a precise surgical blade used for detailed cutting. A craft knife is suitable for thicker materials, whereas a scalpel is used for fine, detailed work.

Question 4: List two types of rulers used in manual drawing and describe their specific uses.

Answer: A straight ruler is used for drawing straight lines and measuring lengths, while a T-square helps draw horizontal lines and ensure alignment in technical drawings.

Question 5: Explain how a marking gauge is used in manual drafting. What advantage does it offer?

Answer: A marking gauge is used to scribe parallel lines at a set distance from an edge. It provides precise and consistent markings, improving accuracy.

Question 6: Sketch a simple ergonomic handle for a tool. Label at least three features that make it comfortable to hold.

Answer: A correct sketch would show an oval or rounded shape to fit the hand, with textured grip areas, and a slightly curved profile to reduce strain.

Question 7: Draw a basic layout of a manual cutting mat and indicate where the grid lines are typically placed. Label the key features.

Answer: A large rectangle with evenly spaced grid lines crossing the surface, marked with measurements. Label the grid lines, measurement markings, and cutting surface.

Question 8: Design and sketch a simple tool holder for manual drafting tools. Include at least three compartments or sections.

Answer: A correct sketch would show a rectangular container with divisions for pencils, rulers, and erasers, each section clearly separated and labeled.

Question 9: What safety precautions should you take when using manual cutting tools such as craft knives or scalpels?

Answer: Always cut away from your body, use a cutting mat, keep blades sharp to reduce force needed, and store blades safely when not in use.

Question 10: Describe the process of using a metal straightedge during drawing. Why is it preferable over a flexible ruler?

Answer: Place the straightedge along the desired line, hold it firmly, and draw a line along its edge. It is preferable because it provides a straight, stable guide for accurate lines.

Question 11: Identify two manual tools that can be used to create texture in drawings and explain how they are used.

Answer: Pencil with different shading techniques (hatching, cross-hatching) to create texture. Stippling using a pen or pencil to produce a textured surface.
