Question 1: Describe a simple cube in three-dimensional space. Draw the front, top, and side views of the cube in the spaces provided. Ensure that the views align correctly according to orthographic projection principles.

Answer: The front view shows a square; the top view shows a square directly above the front view; the side view also shows a square aligned with the front view. All views should be proportionally accurate with consistent edges.

Question 2: Sketch a rectangular box that is 100mm long, 50mm wide, and 30mm high. Draw the front, top, and side views in the provided spaces, maintaining correct proportions and alignment.

Answer: The front view displays a rectangle 100mm by 30mm; the top view shows a rectangle 100mm by 50mm; the side view shows a rectangle 50mm by 30mm. All views should be aligned correctly according to orthographic conventions.

Question 3: Draw a detailed orthographic projection of a simple L-shaped bracket. Include the front, top, and side views, ensuring the edges align properly between views.

Answer: The front view should display the L-shape with correct height and width; the top view shows the shape's outline, including the cutout or flange; the side view should reflect the depth and height, aligning with the other views.

Question 4: Sketch a simple ergonomic handle for a tool. Include a front view and a side view in the space provided. Focus on smooth curves and a comfortable grip shape.

Answer: A sketch showing an ergonomic handle with a rounded, contoured shape that fits comfortably in the hand. The front view should display the overall width and shape, while the side view emphasizes the contour and thickness.

Question 5: Describe the shape of a cone and draw its orthographic views (front, top, side). Pay attention to the tapering surface in your sketches.

Answer: The front view shows a triangle or an ellipse depending on the cone's orientation; the top view shows a circle; the side view should also depict a triangle or ellipse, with the alignment consistent across views.

Question 6: Draw a simple two-dimensional representation of a gear with 12 teeth. Include the front view and the top view, showing the teeth as evenly spaced protrusions.

Answer: The front view should display a circle with evenly spaced teeth protruding outward; the top view shows a circle with the teeth arranged around the circumference, maintaining symmetry and even spacing.

Question 7: Describe a cylindrical object and draw its orthographic projections (front, top, side). Ensure the views accurately represent the shape's features.

Answer: The front and side views show rectangles representing the height and diameter; the top view shows a circle indicating the cylinder's cross-section. All views should be aligned correctly.

Question 8: Design and sketch a small, compact mobile phone holder. Draw the front view and a side view, emphasizing stability and ease of use.

Answer: A sketch featuring a base with a slight incline, a support arm, and a cradle for the phone. The front view shows the overall height and width, while the side view emphasizes the support angle and stability features.

Question 9: Explain the importance of consistent line types in orthographic drawings. Then, draw a simple object (e.g., a box with a cutout) using different line types to represent visible edges, hidden edges, and section lines.

Answer: Consistent line types help differentiate between visible edges (solid lines), hidden edges (dashed lines), and section cuts (thick or dashed lines). The drawing should clearly distinguish these features accordingly.

Question 10: Sketch a small, detailed model of a keychain with a loop and a decorative pendant. Include the front view and side view, paying attention to proportionality and detail.

Answer: The front view shows the loop and the pendant's outline; the side view emphasizes the thickness of the loop and the depth of the pendant. Both views should be proportionally accurate and aligned.
