Question 1: Draw the front and top views of a simple rectangular box measuring 50mm in length, 30mm in width, and 20mm in height. Ensure all edges are clearly marked.

Answer: The front view should show a rectangle 50mm wide and 20mm high. The top view should show a rectangle 50mm long and 30mm wide. Both views should align correctly to represent the object accurately.

Question 2: Sketch the side view of a triangular prism with a base length of 40mm, height of 30mm, and length of 50mm. The sketch must include the correct shape and proportions.

Answer: The side view should display a triangle with a 40mm base and 30mm height, with the length extending perpendicular to the triangle, indicating the depth of 50mm.

Question 3: Draw a 3D isometric projection of a cube with edges measuring 40mm. Use light guidelines to represent the three axes.

Answer: The drawing should depict a cube with all edges equal to 40mm, showing three visible faces in an isometric view with proper angles and proportions.

Question 4: Create a detailed front view of a cylindrical object with a diameter of 20mm and a height of 60mm. Show the circular cross-section clearly.

Answer: The front view should be a rectangle 20mm wide and 60mm high, with the top and bottom edges representing the circular ends of the cylinder.

Question 5: Sketch a simple L-shaped bracket with dimensions: 50mm length, 20mm width, and 10mm thickness. Indicate the two main faces and the 90-degree bend.

Answer: A correct sketch should show the L-shape with two rectangular faces connected at a right angle, clearly indicating the dimensions and the thickness of 10mm.

Question 6: Draw the top view of a rectangular object with a circular hole of 10mm diameter located centrally. The rectangle measures 80mm by 40mm.

Answer: The top view should show a rectangle 80mm long and 40mm wide, with a circle of 10mm diameter centered within the rectangle.

Question 7: Sketch the side view of a rectangular prism with a cut-out section in the middle, showing the cut as a horizontal gap. The overall dimensions are 100mm long, 50mm high, and 30mm wide.

Answer: The side view should display a rectangle 50mm high and 30mm wide, with a horizontal gap indicating the cut-out section, aligned correctly along the length.

Question 8: Draw an orthographic projection of a wedge-shaped object, with a sloped top surface. The base measures 60mm by 40mm, and the height is 30mm.

Answer: The drawing should include a front view showing the sloped surface, a top view showing the rectangular base, and a side view illustrating the wedge shape with the sloped side.

Question 9: Design and sketch a ergonomic handle with a curved grip. The handle should be approximately 150mm long, 30mm wide, and 40mm high, with smooth contours for comfort.

Answer: A good sketch would show a smooth, ergonomic handle with a curved grip, appropriate proportions, and clear contours indicating comfort features.

Question 10: Create a front view of a complex object that includes a rectangular base with a cylindrical protrusion on top, measuring 20mm in diameter and 40mm high, centered on the base.

Answer: The front view should show a rectangle representing the base, with a centered circle (cylinder) extending upward, aligned properly with the base.
