Pictorial drawings show how many sides of an object?

Pictorial drawings are a type of technical illustration that provides a three-dimensional representation of an object. They are designed to convey an accurate portrayal of the object's shape and form from multiple angles. As such, these drawings typically illustrate three sides of an object: the front, the top, and one side. This allows viewers to grasp a better understanding of the dimensions and spatial relationships within the design. In practice, pictorial drawings—such as isometric or perspective drawings—are particularly useful in fields like HVAC and sheet metal design, where visual communication of complex shapes is essential for accurate construction and assembly.
