Question 1: Draw a front view of a simple rectangular box that measures 80mm in width, 50mm in height, and 30mm in depth.

Answer: A rectangle 80mm wide and 50mm high representing the front view. No hidden lines, with clear dimensions marked accordingly.

Question 2: Sketch the side view of a cylinder with a diameter of 40mm and a height of 70mm. Ensure the view accurately shows the circular base and the vertical height.

Answer: A rectangle 40mm wide and 70mm high representing the side view, with the top and bottom edges indicating the circular profile.

Question 3: Describe how you would draw the top view of a T-shaped object. You do not need to produce the drawing, just outline the key steps and features to include.

Answer: Draw a large rectangle for the main body, then add a smaller rectangle on top of it to represent the crossbar. Show the correct proportions and alignments, indicating the main shape from above.

Question 4: Sketch the front, side, and top views of a cube with edges measuring 50mm. Leave space for each view side by side.

Answer: The front view is a square 50mm x 50mm, the side view is identical, and the top view is also a 50mm x 50mm square. All views should be aligned correctly with proper projection lines.

Question 5: Explain the difference between an orthographic projection and an isometric drawing. Use clear language suitable for a beginner.

Answer: Orthographic projection shows different views (front, side, top) of an object from specific angles, using 2D views. Isometric drawing is a 3D representation where the object is viewed at an angle, showing three sides simultaneously.

Question 6: Draw a simple wireframe of a chair viewed from the front and the side. Focus on the outline and basic structure, not details.

Answer: The front view should show the legs, seat, and backrest outline, while the side view should include the depth of the seat and the backrest's profile. Keep proportions consistent.

Question 7: Identify three important rules to follow when creating accurate orthographic drawings.

Answer: Use consistent scale, include all visible edges, and project features correctly with proper alignment across views.

Question 8: Sketch a simple L-shaped bracket with dimensions: 60mm long, 20mm wide, and 10mm thick. Show the front and top views side by side.

Answer: The front view shows the L-shape with the length and height, while the top view shows the width and length, with clear indication of the 10mm thickness.

Question 9: Describe how to convert a front view into a side view for an object with a rectangular profile. Mention key considerations.

Answer: Identify the depth of the object, project the profile to the side, and maintain the same height. Ensure the side view matches the width of the front view and accurately represents the shape's profile.

Question 10: Sketch the three main views (front, side, top) of a simple rectangular prism with dimensions 100mm x 50mm x 30mm. Leave space for each view.

Answer: The front view shows a rectangle 100mm wide and 50mm high, the top view a rectangle 100mm x 30mm, and the side view a rectangle 50mm x 30mm, all aligned properly with projection lines.
