The power and potential of the modern personal computer, has also allowed use in functions such as technical drawing tool. So much so, that it has practically disappeared draughtsman technician profession, replaced by the CAD draughtsman or Computer Aided Design Draftman. Classic drawing tables with variable height, adjustable angle, etc. are to be used as tables to view or revise plans already printed on paper.
Computer Aided Design has increased the quality and quantity of information produced by engineers, architects, and designers in general, as well as allowing the handling and storage of the plans of projects in physical spaces as small as a portable memory.
The use of libraries of digital information with template type and an almost unlimited amount of symbols, arrays, details standard, etc., as well as the possibilities of resize, copy, and modify all these elements have changed the way in which their products are designed by professionals graphics or drawings.
It is not cumbersome to make modifications according to the designs of professionals from other areas of the project and, for example, facilitates the exchange of information in a same team for the coordination of the different disciplines of the project.
Additionally, we must mention the inclusion, from the 1990s of the design in 3 dimensions and the inclusion of animation for the visualization and analysis of the design. This jump genre a new management model of design that has enriched the inventiveness of design professionals, architects and engineers.
The pioneering and most popular commercial computer-assisted design program is AutoCad, although there are also lesser-known as TurboCad, Icad, VariCad and LibreCad versions.
Finally, and since we are talking about Software, we want to touch the subject of file extensions. These are nothing more than the identifier that will follow the point, in the files that generate the programs, for example: mywriting.text (in this case refers to a so-called flat text file). This, specifically, is an agreed identification at the universal level.
There are many extensions of files that are in standard use agreed “for all” involved. It is the case of .exe for executables, and more.
The creators of Software used to differentiate the data files generated by its programs, very particular extensions and, unless we talk about compatibility with any standard, unique to that family of files and developer. For example, .xls is an identification of the Excel files. Another example is .dwg for AutoCad files or .doc for Word files.
