The evolution of engineering graphics is a rich historical trend, from the ancient Egyptians who used angle rulers to ancient Greece, where the stylus and needles were the tools needed to create lettering. The invention of protractors, adjustable angle rulers, X-ray pencils and the discovery of various projection objects in the late 18th century revolutionized engineering design.

Engineering modeling today is the result of all these trends, and with the advent of computer-aided CAD drafting software in two dimensions (2D) and three dimensions (3D), there has been a departure from the traditional style of drawing. In all these historical trends in graphic representation, the goal remained: the creation of a language.

In some industries, designs, drawings and other documentation are still written on paper. Framing the problem in the current state of technology leads to some common nagging that things were better than they were before. CAD was a skill honed by dedicated draftsmen before it was necessarily used by engineers. Some complain that young engineers do not have classical drawing skills and that a crisis is looming, despite the

fact that CAD is now available to more people than ever. Many companies have archaic methods and still use paper-based filing systems. In today’s digital world, this is no longer a viable way of working. Overcoming organizational inertia and tradition is never easy, and so it may be tempting to dismiss the above suggestions as too intimidating. Rarely are such problems overcome by not having a workable solution, but rather simply by not trying.

The scientific discoveries and related technical advances that have brought about such amazing industrial upheavals and have given such huge impulses to the rapid and massive accumulation of capital, clearly show how important the CAD design process is for capitalization purposes. We live and work in an increasingly conscious world where recycling is important.

Transferring paper documents and documents to a digital system is a great way to do this. Moreover, businesses are expected to minimize their carbon footprint and reduce environmental damage. In addition to reducing environmental impact, going digital also helps improve business processes and increase efficiency. Files can be stored on computers and cloud storage for instant access. In addition, drawings, diagrams and sensitive

information can be processed and edited using advanced software instead of manual replacement. These new types of  programs were originally called applications (or application programs). The main difference between 3D modeling and 2D design is that mechanical equipment is modeled, not drawn.

3D modeling has truly become a standard tool used in engineering, especially in mechanical engineering. Direct access to the original data of parts and assembly files is key to fully exploiting the intelligence stored in models, b this is easier said than complete when design engineers use one system programmers use

something else. Few of the best nesting software systems allow users to save programming time and associated costs by providing seamless access to these assemblies and parts without the need to export and convert between file types. When creating any type of document using a computer, you must save it as a file. File conversion is an integral part of CAD design. When using software such as Compass 3D, Solid Works, CATIA or Auto desk, your 2D and 3D designs are created in different file formats. This source contains all the information regarding the document and how it should be processed and rendered. Different software uses different proprietary or non-proprietary file formats. Because of this many different file formats and software, CAD software often needs to be converted. A business may have a collection of projects or plans, but they may not have the software to view them.

CAD design works in much the same way. For example, a Compass 3D assembly document or 3d file will contain information about the contents of the number of model parts and its references. When using software such as Auto CAD or Compass 3D, you create a digital document. The file format determines which program you can use to view the document. In addition, it will also dictate what is in the document. For a CAD file, this means the design itself.

Why Use 3D Modeling?

It seems that people have a strong tendency to associate 3D modeling with architectural design only. It’s not entirely wrong, but 3D modeling can be used in almost any industry, including consumer products, apparel design, and even educational purposes, such as geometry classes in schools. The same is true for other fields of research, such as biology or chemistry, where 3D models are used as visual representations of body organs or the chemical structure of an atom.

Getting a visual representation of an object is only one benefit. In addition to getting an accurate rendering of an object, 3D modeling (at least from an engineering point of view) gives a lot of technical detail with almost zero errors, if any. It means, that computer-aided design and drafting (CAD) can help professionals create 3D models for both theoretical (in the case of prototypes) and existing objects (such as a 3D model of the human heart), with much greater detail. Students and hobbyists can play with 3D modeling to familiarize themselves with designs or even create simple objects such as furniture, toys, household items, and other creative projects.

Important features of 3D and 2D CAD files

3D modeling is a mathematical, systematic and graphical representation method used to create a digital representation of an object using CAD software. The model reflects the most important features of everything that is modeled. It maintains an understanding of design in its simplified form and is basically the final representation of components and processes.

Documentation is a very important part of any design process. Before we look at the actual file types, it’s important to understand their different properties.drawing in different ways. Moreover, some types of CAD files may be limited to 2D displays only suitable for showing the design to the end user. Below are some of the main features of the 3D and 2D CAD file formats:
