Engineering DrawingEng

44、ineering drawing is not only the province of the draftsperson, but also the language of the engineer. It is their means of developing and recording their ideas, and conveying them to others. Every engineer will be using and referring to some form of drawings almost every day. They will often be prod

Usually, they make the preliminary sketches and design drawings in accordance with principles of the engineering drawing, because this is the most unambiguous way to convey and record information. It is also likely that every engineer at sometime will

46、be checking the work of designers and drafters and approving drawings before they are sent to the workshop. When engineers sign off the final approval of a drawing, they will take responsibility for it. An overlooked error in the drawing could becostly. So a drawing must be the true and complete sta
