Computer-Aided
Computer-Aided Design (CAD) is the use of computer technology to aid in the design of a product, particularly the drafting of a part or the product—a part visual (drawing) and part symbol method of communications particular to a specific technical field. It is in origination, the use of computers to aid the art of drafting—the integral communications of technical drawings — which for a three dimensional object are typically represented by three projected views at right angles —drafting is the Industrial arts sub-discipline which underlies all involved technical endeavors. Current CAD software packages range from 2D vector base drafting systems to 3D solid and surface modellers. Modern CAD packages can also frequently allow rotations in three dimensions, allowing viewing of a designed object from any desired angle, even from the inside looking out. Some CAD software is capable of dynamic mathematic modeling, in which case it may be marketed as CAD.
Architecture is the art and science of designing and constructing buildings and other physical structures. A wider definition often includes the design of the total built environment, from the macro level of how a building integrates with its surrounding manmade landscape (see town planning, urban design, and landscape architecture) to the micro level of architectural or construction details and, sometimes, furniture. The term "Architecture" is also used for the profession of providing architectural services.
Architects are primarily driven by the creative manipulation of mass, space, volume, texture, light, shadow, materials, program, and pragmatic elements such as cost, construction and technology, in order to achieve an end which is aesthetic, functional and often artistic. This distinguishes architecture from engineering design, which is driven primarily by the creative manipulation of materials and forms using mathematical and scientific principles.



MY OPINION
It is so fine these day.So, became becomes lazy and lazy whether is.Must pay attention fast and take part hard in period.
In fact, because of project, did not sleep during 3 day.So, was confused, and tired.
Professor is sorry.Really sorry .........ㅠㅠ
