![]() This stage of the development process involves identifying product specifications and functions that engineers use when applying function commands in a CAD program. ![]() They thoroughly research the project before beginning to ensure they understand the item's function and all specifications. Plan the projectīefore engineers create technical drawings and blueprints within a CAD program, an engineer or draft technician communicates with design teams and collects all necessary planning documents. The following steps provide additional insight into how professionals use drawing in engineering: 1. CAD is the use of computer systems and software to aid in the creation, modification, analysis or optimization of a design. In the past, design engineers and technicians would use manual tools and systems to create engineering drawings, but now they use computer-aided design (CAD) software to design and develop plans.

The engineer distributes these drawings to a manufacturing department to produce the parts, to an assembly department to put the parts together, then to any vendors, archives or other company departments. An engineering drawing helps to define the requirements of an engineering part and conveys the design concept. Engineering drawings are also known as mechanical drawings, manufacturing blueprints and drawings. What is an engineering drawing?Īn engineering drawing is a subcategory of technical drawings that show the shape, structure, dimensions, tolerances, accuracy and other requirements needed to manufacture a product or part. In this article, we discuss what engineering drawing is, how to make one, basic components of engineering drawings and some frequently asked questions about engineering drawings. Learning more about these drawings can help you understand how your workplace might use them. Engineers or draft technicians create technical drawings digitally by making a model of the product or building, displaying the model from different angles and adding information. Most engineering projects start as drawings that convey details about an engineering or construction project.
