平面弯管的计算机辅助设计与绘图，以ＡｕｔｏＣＡＤ为图形支撑软件，以Ｃ语言为编程语言，通过．ＤＸＦ文件，将Ｃ语言程序的计算结果与ＡｕｔｏＣＡＤ的图形显示连接起来，在ＡｕｔｏＣＡＤ系统下显示和输出设计图样。平面弯管的计算机辅助设计与绘图具有以下特点：①计算简便，数据准确，所有计算点都用坐标值标出，便于弯管制作与安装；②程序简短紧凑，利用图形函数库和汉字函数库，使程序简短、明了；③设计、绘图全部自动化，平面弯管计算机辅助设计与绘图作为一个应用程序，设计者对具体弯管进行计算与绘图时，只需提供很少的体型参数，即可得到详细的设计数据与准确的设计图。
Computer-aided design and drawing of flat elbows, with AutoCAD as the graphics support software, with C language as programming language. DXF file, the calculation results of the C language program with AutoCAD graphical display connected to display and output AutoCAD design drawings. Computer-aided design and drawing of flat elbows have the following characteristics: ① The calculation is simple and the data is accurate. All the calculation points are marked with coordinate values to facilitate the manufacture and installation of elbows. ② The program is compact and compact. By using the graphic function library and Chinese character library , So that the program is short and clear; ③ design, drawing all automated, flat pipe computer-aided design and drawing as an application, the designer of the specific calculation and drawing elbow, only a small body size parameters to provide, you can Get detailed design data and accurate design drawings.
