Many architects, designers and engineers usually use CAD otherwise known as ‘computer -aided design’ as a tool in their work especially for designing 3D objects. This program is also useful in drafting, technical drawings as well as schematics. CAD is basically a design form used in creating prototypes, models and ideas. Technical drawing and drafting are done more efficiently with the use of CAD and not only that but also through CAD the designs can be tested in simulations for producing a more effective design such as determining whether a certain design is strong, can withstand pressure, etc. such as in the case of designing a bridge. Through the various types of CAD programs, designing structures, molecules, mechanical components and more is made possible. Also, through such types one can freely alter the feel and look of something just by clicking some buttons in his computer without painstakingly drafting manually.
For casual users, the various types of CAD programs make it possible for them to decide how to organize their furniture, how to make their gardens look cozy and a lot more possibilities by dropping and dragging elements to create a pleasant configuration. The many uses of CAD programs include shipbuilding, automotive as well as aerospace industries, architectural and industrial designs, forensic labs for recreating crime scenes with the use of a computer, computer animation used in special effects for movies, prosthetics, advertising as well as technical manuals.
-2-Dimensional Program- Otherwise known as 2D, is one of the types of CAD programs which is considered the very basic type there is. Here the designer is able to create drawings with the use of Y and X axes. Designs in 2D do not have any depth since they are only displayed by outlines. This is quite basic in which it solely depends on the designer’s skill only with the use of primary geometric figures. 2D is also one of the various types of CAD programs which is used in creating flat drawings. The objects in 2D are usually made with the use of curves, slots, ovals, circles and lines. 2D is capable of creating Bezier curves, polylines and splines, defining hatching patterns and providing materials generation bill. Commonly architects as well as some professionals use this type in their works wherein any depth is not necessary.2D programs include Medusa, CATIA v4, CADDS 5, CADkey, and AutoCAD.
-3-Dimensional Program– Also referred to as 2D, is one of the types of CAD programs which is more expensive. Its models are created in such a way that is realistic which gives designers the chance to give solutions to potential problems sooner and with fewer costs on production. This comes in many different types with various applications as well as detail levels. CAD is one of the types of CAD programs which features true depth in which the designer can rotate the design in 360 degrees in 3 various angles.
-2.5Dimensional Program– This program is between 3D and 2D. 2.5D models are prismatic. Similar to 2D, it only uses primary geometric figures. Designs in this type do not have true surfaces or strong modeling figures, and are made basically with the use of lines.
