The Engineering Design Process

The engineering design process is a series of steps that engineers use to create solutions to problems. It is a structured approach to problem-solving that involves identifying a problem, defining the problem, generating potential solutions, evaluating those solutions, selecting the best solution, and implementing and testing that solution. The engineering design process is iterative, meaning...

Drawing Instruments

Today, engineering drawings are very seldom constructed by hand. CAD technology is the universal choice in industry. However, it is useful to include a discussion of the instruments that were historically used for this purpose. Manual drafting is an appropriate way teach the fundamentals of engineering graphics. The most important concepts of engineering graphics are...

Line Conventions and Lettering

Engineering drawings are a critical part of the design and manufacturing process, providing detailed information on dimensions, materials, and tolerances. To ensure clear and consistent communication, drawings must adhere to specific conventions for line types and lettering. These conventions are defined by the American Society of Mechanical Engineers (ASME) in the Y14.2 standard. Proper use...

Geometric Construction

Geometric construction is the process of creating precise shapes, angles, and dimensions using only basic tools like a compass, straightedge, and protractor, or in digital contexts, precise drawing tools within CAD software. Unlike freehand drawing, geometric construction follows strict rules and methods, relying on the principles of geometry to create accurate figures that maintain their...

Graphical Projection Systems

Graphical projection systems encompass a wide range of methods for representing three-dimensional objects on a two-dimensional surface. These methods are fundamental to engineering drawings, as they provide the means to communicate complex shapes, dimensions, and spatial relationships in a clear and interpretable manner. Each method offers a different approach to visualizing an object, catering to...

Dimensioning

Dimensioning is a crucial aspect of engineering drawings, which plays an essential role in communicating design specifications and requirements to manufacturers, engineers, and other stakeholders. Essentially, dimensioning refers to the process of specifying the exact size, shape, and location of different parts and features on an engineering drawing. Dimensioning is vital in the engineering industry...

Working Drawings

A working drawing, also known as an engineering drawing, serves as a detailed blueprint for the production of a component, product, or structure. It provides the precise specifications necessary to manufacture or construct the item accurately. This includes all the dimensions, shapes, materials, tolerances, and assembly instructions needed to guide machinists, fabricators, or construction workers....

Graphical Calculators and Nomograms

Graphical Calculators: Graphical calculators are electronic devices designed to perform a wide range of mathematical computations while also providing visual representations of mathematical functions and data. These calculators typically feature high-resolution screens that allow users to input equations, graph functions, and analyze data with ease. They are commonly used in educational settings, scientific research, engineering,...

This section serves as a resource for understanding some aspects of Siemens NX, a powerful CAD/CAM/CAE software suite used for product design, engineering, and manufacturing. The topics covered here cover both fundamental and advanced features of NX, ranging from user interface basics to complex modeling techniques and drafting workflows. As you explore this section, you'll...

CAD – AutoCAD

AutoCAD is a popular and versatile computer-aided design (CAD) software developed by Autodesk, widely used in industries such as architecture, engineering, construction, and manufacturing. Known for its precision and comprehensive toolset, AutoCAD allows users to create detailed 2D and 3D models, draft technical drawings, and produce professional-grade engineering drawings. Since its launch in 1982, AutoCAD...
