Question 1: Describe the key characteristics of isometric projection that differentiate it from other types of drawing projections.

Answer: Isometric projection shows three dimensions on a single plane with equal angles of 120° between axes; objects are scaled equally along all axes, and there is no perspective distortion.

Question 2: Sketch a simple cube in isometric view in the space provided. Ensure all edges are accurately drawn at 30° angles to the horizontal.

Answer: A correctly drawn isometric cube with all edges at 30°, with visible faces forming a hexagon-like shape, with parallel edges and equal proportions.

Question 3: Identify and explain three advantages of using isometric drawings in product design.

Answer: Advantages include: 1) Allows clear visualization of complex 3D objects on a 2D surface; 2) Maintains proportionality without perspective distortion; 3) Facilitates accurate measurement and scaling of designs.

Question 4: Draw an isometric view of a rectangular prism that measures 60mm in length, 30mm in width, and 40mm in height. Use the space below.

Answer: A rectangular prism accurately depicted in isometric view, with all three dimensions proportionally scaled and edges aligned at 30° angles. The shape appears as a skewed box with the specified dimensions.

Question 5: Create a step-by-step explanation of how to construct an isometric grid on your drawing paper.

Answer: Start by drawing a series of parallel lines at 30° to the horizontal, spaced evenly. Then, draw a second set of parallel lines at 30° in the opposite direction, intersecting the first set to form a grid of equilateral triangles.

Question 6: Sketch a simple cylindrical object, such as a can, in isometric view. Use the space provided.

Answer: A correct sketch shows a circle at the top and bottom in isometric view, with the sides aligned at 30°, forming an oval shape in perspective, and the height proportionate to the diameter.

Question 7: Explain why isometric drawings are useful in engineering and how they help in understanding object structures.

Answer: Isometric drawings are useful because they provide a clear, three-dimensional view of objects on a flat surface, making it easier to understand shape, proportions, and spatial relationships without perspective distortion.

Question 8: Draw a small, detailed isometric staircase with three steps in the space below. Each step should be clearly distinguishable.

Answer: A staircase with three steps, each step extending at 30° angles to the base, with consistent rise and run, clearly depicting the three levels in isometric view.

Question 9: Describe the process of converting a 2D orthogonal drawing into an isometric view.

Answer: Identify key features in the orthogonal drawing, then project lines at 30° angles to represent depth, maintaining proportional scaling, and redraw the object in isometric perspective to depict 3D form.

Question 10: Sketch a simple house structure in isometric view, including a roof, walls, and a door. Use the provided space.

Answer: A basic house with rectangular walls, a pitched roof (triangular in isometric view), and a door on one wall, all aligned with 30° axes, proportionally scaled.
