AutoCAD Based Calculation Software Development of Drip Irrigation Pipeline

In order to realize the integration of design and calculation of dripping irrigation pipeline in AutoCAD, this paper developed a set of software which is embedded in AutoCAD and used for pipeline calculation. As an integrated development software, VBA can share and exchange data with other VBA programs directly. This makes connecting with other software and processing data more easy. Using AutoCAD VBA, this paper developed the software for the automatic design of drip irrigation. Under this circumstance, user can complete data analysis and calculation thus makes the design work more efficiency.. The software contains three modules, knowledge module, calculating module and documents managing module. Through these facilities, Not only can the users finish the work of design, but also it produces the Excel to transmit the data, which is necessary for the design or choosing equipments. Further more it is convenient to maintain and upgrade.
