Computer model is system of computers that reproduce conceptual model of a system. Conceptualization in computers is useful to mathematical modeling to any field of sciences such as physics, astrophysics, chemistry biology, economics, psychology, social science and engineering.
Computer-aided design or sometime computer aided drafting (CAD) involves computer technology to design or draw objects in a two-dimensional (2D) space and three-dimensional (3D) objects. It is an important art used in computer technology application such as automotive, shipbuilding, aerospace industries, architectural designs, etc. If you see animated series in movies and advertisements, CAD is applied for the special effects. CAD is also utilized in making tools and machinery. Architects, designers and developers used CAD in drafting and designing of building structure.
In this model, you can let your electronic drawing be adjusted as many as you can. You will able to transmit it online and can be printed and copied at low cost. You can do anything on your drawing through CAD; you can produce images that can be realistic of you own ideas, you can view at any direction or position, and you can calculate physical properties of your drawing.
It exposed not only visual but also the system of your model. The model maintains the differences at the time of excavation made by original model. The content for the CAD model cannot be lost.
It utilizes to program inspection devices which allows beginning a process without a physical part. Without CAD model during inspection, the inspection will not be accurate because physical part will be out of specification. CAD model can be used for inspection report. This doesn't require reading all the 100 pages report but recognizes dimension number.
CAD model is very beneficial to engineering, archaeological, architectural and mapping projects. Drawing objects may not be so hard for those who are engaged in a profession which needs designing and drafting with the use of CAD programs.
