Computer Assistant Design And Draw System For Water Supply And Drainage Of Building

In recent years, the ratio of Engineering-Map-Drawing by CAD in the Architecture Engineering Profession is almost and already 100%, whereas, the development of software in Water Supply and Sewerage Profession however falls behind to some degree. Combining the experience that be engaged in author's job with courses that currently learned, programmed this set of <> ,and used in the engineering works.This dissertation analyses the situation in Water Supply and Sewerage designing of the present, putting forward some improvement of water supply and sewerage engineering in the building based on the system of AutoCAD, and obtaining the initiative results in some aspects below:1. For the designers of Water Supply and Sewerage profession, the system is made to be capable of identifying the instruction combined with some other ones, and replace the original AutoCAD system instruction with simplified ones which is made up of one or two letters in the alphabet, so as to simplify the AutoCAD system and expand the function of this software.2. After programming the aided calculation system, this system is capable of bringing the commonly used charts in Water Supply and Sewerage design into being in digital forms, and, for designers of this profession, the software provides the function of choosing types of equipments and calculating the power of water flow, which is not available in the former AutoCAD system.3. As the programming of friendly CAD interface that is suitable for the users of, designers of Water Supply and Sewerageprofession are able to work thought this interface, which greatly makes the users convenient while using this software.The author completed the designing and coding procedure mentioned above and put them into use, obtaining good results.
