Final answer:
The advantage of double line drawings over single line drawings is increased clarity, making it easier to highlight important details and convey accurate information. They are commonly used in technical drawing to represent complex systems without the need for three-dimensional models. Double line drawings also allow for easy annotations and modifications.
Step-by-step explanation:
The advantage of double line drawings over single line drawings is increased clarity. By using two lines instead of one, important details and features can be highlighted and distinguished more easily. This can help in conveying accurate information and communicating ideas effectively.
For example, in technical drawing, double line drawings are commonly used to represent different parts of a mechanical system or a building. The use of double lines allows engineers and designers to create detailed drawings without the need for three-dimensional models. This saves time and accelerates the engineering work process.
Furthermore, double line drawings can also facilitate annotations and modifications. With two lines, it is easier to add annotations, labels, and dimensions to the drawing, making it clearer and more informative.
