What is needed when the details inside the part become more complex?
What will be an ideal response?
As the details inside the part become more complex, additional invisible lines are needed to show the hidden details accurately. This tends to make the drawing increasingly more difficult to interpret. One technique used on such drawings to simplify them is to cut away a portion of the object, resulting in a sectional view. This exposes the inside surfaces. On cutaway sections, all of the edges that are visible are represented by visible edge or object lines.
