Question 1: Draw the front view of a simple rectangular box with a width of 80mm, height of 50mm, and depth of 100mm. Ensure your drawing includes clear lines and accurate proportions.

Answer: A front view showing a rectangle measuring 80mm wide and 50mm high. The depth (100mm) is not visible in this view but should be indicated with hidden lines if necessary.

Question 2: Sketch the top view of a cylindrical object with a diameter of 40mm and a height of 60mm. Include the circular top and the side profile outline.

Answer: A circle with a diameter of 40mm representing the top view, and a side profile showing the height of 60mm, with proper proportions and clear lines.

Question 3: Draw an isometric projection of a cube with an edge length of 50mm. Show all three visible faces clearly in your sketch.

Answer: A cube with equal edges of 50mm, drawn in isometric view, with three faces visible, each accurately proportioned, with edges at 120° angles.

Question 4: Create a detailed front view of a wedge-shaped block that is 60mm wide at the front, 100mm wide at the back, and 40mm high. Include hidden lines if necessary.

Answer: A rectangle 60mm wide and 40mm high at the front, with the back edge extending to 100mm width, showing the wedge's slope. Hidden lines indicate the back edge if not directly visible.

Question 5: Sketch a side view of a T-shaped object where the vertical part measures 80mm tall and 20mm wide, and the horizontal top bar measures 60mm wide and 20mm thick.

Answer: A T-shape with a vertical rectangle 20mm wide and 80mm tall, topped with a horizontal rectangle 60mm wide and 20mm thick, aligned centrally at the top.

Question 6: Draw the elevation view of a rectangular prism that is 100mm long, 50mm wide, and 70mm high. Show the correct proportions and outline.

Answer: A rectangle representing the elevation, with height of 70mm and width of 50mm, indicating the front face of the prism, with lines parallel and proportional.

Question 7: Sketch a simple orthographic projection of a cone with a base diameter of 30mm and a height of 50mm. Show the side and top views.

Answer: A top view with a circle of 30mm diameter, and a side view showing a sloped line from the apex to the base circle, illustrating the cone's shape.

Question 8: Draw a plan view of a key-shaped object. The key should have a handle part that is 20mm wide and 40mm long, with a blade extending 60mm, ending with a rectangular bit 10mm wide.

Answer: A plan view showing a handle rectangle (20mm x 40mm), with a connecting shaft leading to a longer blade (60mm), ending with a small rectangular bit (10mm wide).

Question 9: Construct a three-view orthographic projection of a rectangular box with a circular hole through the center. The box measures 80mm x 60mm x 40mm, and the hole has a diameter of 20mm.

Answer: The three views (front, top, side) should show the rectangular outline with a central circular hole correctly positioned in each view, with dashed lines indicating hidden features where appropriate.

Question 10: Sketch a profile view of a stepped block that has a lower section 100mm long, 50mm high, and a top section 60mm long, 30mm high, positioned on the right end of the lower section.

Answer: A profile showing a base rectangle 100mm long and 50mm high, with a smaller rectangle (60mm x 30mm) attached at the right end, representing the step.

Question 11: Draw a detailed isometric view of a rectangular tray with internal dimensions of 150mm x 100mm x 30mm deep, including the outline of the top edge and interior base.

Answer: A 3D isometric sketch showing the rectangular outline of the tray, with visible edges, interior base lines, and depth, accurately proportioned.
