The System Of Computer Aided Design For The Building Metal Structures Doors And Windows In The Network Circumstances

The industry of building metal structures is such an industry engaged in designing and producing various metal structure products such as doors and windows, curtain walls and daylighting ceilings. In current process of designing and producing doors and windows, there exist the following problems: long design cycle, high error rate, large amount of repetition work, lack of information share. Therefore, it is significant to develop the system of Computer Aided Design Product for building doors and windows, aimed at solving the problems above and adapting to the development of the industry of building doors and windows in China.With the analysis of working conditions in enterprises and the similar current researches, according to the characters of building doors and windows, this paper aims at dealing with the problems of computer aided design of building doors and windows in network circumstance, focuses on the key technology of drawing processing, material processing, information share and data integration in network circumstance, establishes the open basic database, and develops the CAD design system for building doors and windows in network circumstance.The system is a subsystem of the CADPM which can composite with several other subsystems. At the same time it is perfect in drawing processing and material processing. With the using of database, it can fulfill the drawing processing and material calculation for any single doors and windows or combined doors and windows. This system is practical, open and adaptable, which make it capable to effectively raise the designing quality and efficiency, and thereby make the enterprise highly competitive in the market competition.
