What type of line shows hidden objects or edges and can indicate items vertically placed, such as shelves over a counter?

The selected answer is appropriate because a dashed line is commonly used in drafting to represent hidden objects or edges that are not directly visible in a view. This type of line helps indicate the presence of elements that exist behind or beneath other visible parts of a structure, such as shelves positioned over a counter that cannot be seen directly from the viewpoint of the drawing.

In architectural and construction drawings, it’s crucial to convey complete information, including aspects that are obscured. The use of dashed lines significantly enhances clarity, allowing for a better understanding of the layout and design. This technique helps anyone interpreting the drawings recognize where potential obstructions might exist or where additional features are located, even if they aren't directly observable.

Other types of lines serve different purposes. For instance, a solid line indicates visible edges and outlines, while a leader line is typically used to connect labels or notes to the corresponding drawing elements. A break line denotes areas where material has been omitted for clarity or to represent a break in the object being drawn. Understanding these distinctions is essential for interpreting technical drawings accurately in the context of cabinet and millwork designs.
