Answer
The concrete shoe is designed to channel water away from the house or building. This is crucial for preventing water accumulation around the foundation, which can lead to structural damage.
Conversely, the surface channel is intended to direct water flow towards rivers or drainage systems. It effectively manages surface runoff, reducing the risk of flooding and erosion.

Answer
Begin by transferring the dimensions from the front and top views of the cylindrical pipe elbow onto your answer sheet. Mark the development at point A, ensuring to include a 3 mm seam on both sides. Then, create the unrolled version of the elbow, maintaining the correct measurements and angles. Make sure to use construction lines to guide your drawing without redrawing the figure itself.
