The hardware environment of civil engineering CAD is one of the core contents of this course, which requires students to be familiar with the working principles and main technical indicators of various graphic input and output devices (such as keyboards, mice, scanners, monitors, graphics cards, printers, plotters, etc.). ).
Cad is the abbreviation of Computer Aided Design. It is the most popular aided drawing software system in China at present, which is widely used in many fields such as civil construction, decoration, urban planning, landscape design, electronic circuit, mechanical design, clothing, shoes and hats, aerospace, light industry, chemical industry and so on.
In the application of renderings, the main function of cad is to draw accurately. First of all, you can make a plane reference, because in many landscape renderings, it is impossible to draw accurate terrain with 3D.
The general practice is to import the drawings drawn by cad into 3DMAX as a reference; Secondly, 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. In addition, there are some applications of model base. A large number of professional application modules and software of cad determine that it has its fast and convenient characteristics in a certain field and in a certain aspect.
