Question 1: Describe the difference between a front view and a side view in orthographic drawing.

Answer: The front view shows the object as seen directly from the front, highlighting its height and width. The side view shows the object from the side, revealing its depth and height.

Question 2: Sketch a simple box-shaped object, such as a cube, in the space provided. Include front, side, and top views in your drawing.

Answer: A correct set of orthographic views showing a cube: the front view should be a square, the side view a square, and the top view a square, aligned properly in a projection layout.

Question 3: Sketch a small rectangular box with a lid. Show the front, side, and top views in your drawing. Label each view.

Answer: The front view should show a rectangle representing the box’s height and width. The side view should show the depth and height as a rectangle. The top view should depict the lid as a rectangle matching the width and depth. All views aligned properly.

Question 4: Explain why orthographic views are useful in engineering and design.

Answer: Orthographic views are useful because they provide clear, accurate representations of an object’s dimensions and shape from different angles, making it easier to understand and manufacture the object.

Question 5: Draw a simple L-shaped object using three orthographic views: front, side, and top. Ensure all views are aligned correctly.

Answer: The front view should show the L shape as a rectangle with a cutout; the side view should illustrate the depth of each arm; the top view should clearly depict the L shape layout from above, with all views aligned.

Question 6: Identify the main purpose of using orthographic projections in technical drawing.

Answer: To accurately represent the shape and dimensions of a 3D object in 2D from multiple perspectives, facilitating manufacturing and communication.

Question 7: Sketch a simple cylindrical object, such as a can, in the space provided. Include the front, side, and top views.

Answer: The front and side views should show rectangles with the same height, with the side view indicating the cylinder’s depth. The top view should show a circle or ellipse representing the cylinder’s opening.

Question 8: Design a small key with a rectangular shaft and a rounded head. Draw the three orthographic views: front, side, and top. Label each view.

Answer: The front view should show the rounded head and shaft, the side view should reveal the length of the shaft and the rounded shape of the head, and the top view should depict the shape of the head and the width of the shaft. All views should be aligned correctly.

Question 9: What are the three main views used in orthographic drawing? Briefly describe each.

Answer: Front view: shows the object from the front; Side view: shows the object from the side; Top view: shows the object from above.

Question 10: Draw a simple wedge-shaped object with a sloped top. Include the front, side, and top views in your drawing.

Answer: The front view should show the height and width with the slope indicated; the side view should show the depth and the slope of the top; the top view should be a rectangle representing the top surface with the slope implied.

Question 11: Explain why it is important to keep the views aligned properly in orthographic drawing.

Answer: Proper alignment ensures that all views correspond accurately to each other, making it easier to interpret the object’s true shape and dimensions.
