What is a working drawing?
What will be an ideal response?
An actual drawing of a part shows only the top, front, and right-side views without the imaginary transparent planes. These views show the exact shape and size of the object and define the relationship of one view to another.
A drawing, when completely dimensioned and with necessary notes added, is called a working drawing because it furnishes all the information required to construct the object.
