When learning how to read a manufacturing drawing, it can seem quite daunting because there is so much information to take in. This blog post will break down a drawing and make it easier to understand. But, first thing is first! What is the purpose of a manufacturing drawing if there are 3D models? Manufacturing drawings show numerous features of a part that a 3D model doesn’t. For instance, drawings show the material type, the finish, dimensions, hardware, company information, and other specific requirements. The sole purpose of a drawing is to show all the details of a part. Imagine if you were looking at a single part in your hand, a drawing would essentially describe and illustrate all the details of how to place the part in your hand.
