Custom And Further Development Of Water And Waster Water System Of Architecture On ACAD

Nowadays, the ratio of Engineering-Map-Drawing by CAD in the designment of Water and Waste Water System on Architecture was already 100%. Combing with the experience of design and the courses learned, under the flat of AutoCAD, the author designed this program of Computer Aided Design of Water and Waste Water System of Architecture, and used it in the real works.The assay analyzed the development of the professional software in and abroad, and talked about the actuality of the design, then supplied the ways of how to improve CAD system with this specialty. The assay obtained the results in aspects below:1 , customing the system for designers, building new style of lines, predigesting and combing the commands, and writing some simple but useful programs for the real needs of design.2, according to the drawing standard of Water and Waste Water System, making equipments, instruments, accessories which were often used to be a block, then building magic lantern menu which can be easily used.3, setting up a Aided System of calculating which remedied the lack of calculation function of AutoCAD. The system supplied the calculating program of water supply, drainage, fire fighting, hot water system, and can choose the type of water tank, septic tank and hydrant. The program also thought about the protract of drawing, it can number lines, select data and label data, which improved the efficiency of the design greatly.4, building a data-base for parameters, types of instruments which were often used in design, it can also be used separately.5^ building a friendly CAD interface, designer can easily work with this simple interface of man-machine conversation.Thanks for the help of tutor and schoolmates, the author finished the system on time, and the system got a good effect when be used in real project.
