Engineering design and drawing offer a broad subject that includes many theories and practices. It has different forms of drawing at the lunch table as a basic sketch of a new product idea drawn on a napkin.
Additionally, the drawing comes in the form of a complex series of models for a new automotive design. It uses hundreds of formal drawings that require the construction of a skyscraper. One could learn the purpose and requirements and create meaningful engineering drawings by using this textbook to study engineering drawing and design. The engineering design applications offer an early explanation along with systematic problem-solving techniques.
We use speciﬁc engineering projects or general design along with drafting concepts. The engineering design application mainly uses post guides through a basic example of an engineering design process. It begins with an idea and a basic sketch that ends with manufacturing an actual product.
From an Idea to a Product
The engineering projects and design ideas establish or occur along with an informal setting. For instance, a hand-tool manufacturing company engineer uses a typically adjustable wrench to complete a common home-repair task.
They used the wrench, where the engineers discovered that it was difﬁcult to access a conﬁned location and remove a nut on a piece of equipment. The engineer additionally imagined how the company could manufacture, design, and market a new wrench. We use features that help in making the tool usable in cramped locations. The other day, the engineer and a colleague used the drafting department. The engineer mainly sketches the idea for the new wrench on a napkin by communicating the design to the drafter.
The sketch mostly shows the idea of taking the existing tool design that creates a whole new handle adding an ogee or S-shaped curve design. Additionally, the sketch communicates the concept that takes a current tool with creating a fresh hold of an S-shaped curve design.
Later the same day, the drafter would offer the three-dimensional (3-D) solid model ﬁles using existing wrench design based on the computer-aided design and drafting (CADD) system.
The user mainly uses drafter copies that revise the existing design based on the engineer's sketch. The drafter represents the engineer's new model, who is pleased with the results and requests of a rapid prototype. Rapid prototyping (RP) is a process that creates a physical and functional model from a computer-generated 3-D model. It uses an RP machine, known as a 3-D printer. The RP machines are available that build prototypes from various materials like paper and liquid polymer. The hand-tool company do not have an RP machine. Therefore, the drafter sends ﬁles of the design to a company specialising in RP. The engineer and drafter receive a prototype two days later.
The figure shows the prototype of the new wrench design. The design team tests the prototype in an application similar to what the engineer experienced at home. The prototype worked as expected.
By the next afternoon, the drafter completes the set of working drawings shown in Figure and sends the drawings to the manufacturing department to manufacture and assemble the new product. The manufacturing department needs lead time to design and make the forging dies required to reproduce the parts. Lead time is the time interval between the initiation and the completion of a production process. Forging is the process of shaping malleable metals by hammering or pressing between dies that duplicate the desired shape. The hand-tool company is small, so the drafter is also responsible for creating catalogue art and copy for marketing the product.

Less than two months after the engineer had the initial idea, the first production run of new wrenches is ready to sell. The figure shows the finished product.
We have the best design team that tests the prototype in an application. It works similar to what the engineer experienced at home. The prototype worked as expected. The drafter supports along with completing the set of working drawings by the next day and sends the drawings to the manufacturing department. It helps to manufacture and assemble the new product. The manufacturing department needs lead time to design and make the forging dies required to reproduce the parts. The Lead time is the time interval between the initiation and the completion of a production process. It helps in the process of shaping malleable metals that presses between dies and duplicate the desired shape. Additionally, the hand-tool company is relatively small. It helps to draft for creating catalogue art and add copy for the product marketing.
