About Engineering Drawing

Do you have a basic understanding of Engineering Drawings? If not, don't worry! We are here to help.

Engineering Drawings are two-dimensional representations of three-dimensional objects. They are used to communicate the shape and size of an object, as well as its features, to people who need to use or make that object. There are many different types of engineering drawings, but they all share some basic elements. Let's take a look at what those elements are and how they are used to create a drawing.

Why is Engineering Drawing Important?

Engineering drawings are usually created in accordance with standardized conventions for layout, nomenclature, symbolism, and scaling. The purpose of an engineering drawing is to clearly and accurately capture all geometric features of a product or component so that a manufacturing plan can be developed to make the part. Engineering drawings are typically required for engineered products that must be manufactured to close tolerances.
