What is cad?
CAD is computer-aided and a design software. Its main function is to use computers and their graphic devices to help designers with their design work. Widely used in civil construction, decoration, urban planning, landscape design, electronic circuits, mechanical design, clothing, shoes and hats, aerospace, light industry and chemical industry and many other fields.
Basic functions of CAD:
Plane drawing, drawing assistance, editing graphics, dimensioning, writing characters, layer management, three-dimensional drawing, data exchange, etc.
The role of CAD:
One is plane reference, because in many landscape renderings, it is impossible to draw accurate terrain with 3D, and the general practice is to import the drawings drawn by CAD into 3DMAX as a reference;
The second is to draw complex graphics. In the process of making renderings, it is difficult to complete complex or accurate graphics in 3D, and CAD is needed to assist.
Thirdly, the use of some model bases, a large number of professional application modules and software of CAD determines that it has its characteristics of quickness and convenience in a certain field and aspect, so it is wrong not to treat it objectively.
At present, domestic CAD software is developing rapidly, including Zhongwang CAD, Yaochuang CAD, Chen Hao CAD and CAXA, all of which are outstanding in domestic CAD.
