Abstract: Microwave communication tower, the common structure for radio communication, requires complicated design, calculation and plotting. In order to reduce designer's labour intensity, the software of "CAD for Microwave Communication Tower" is developed, which can take over manual calculation and plotting. The software processes the following three distinguished features; ①Modularization the software consists of four modules (the modules for internal load stress calculation, tower structure design, auxiliary structures design, and tower foundation design), with each module being independent from and relaled with the others; ②Menu operation both MMI and a set of screen menus (including the menu of internal load stress calculation, tower structure, auxilary structure, tower foundation, etc.) are designed for the common users of AutoCAD System. The logically hierarchical menus are easy to operate and clear at a glance; ③Integrated Program Design with the data interface modified and the program of graphic data conversion interface developed, the integration from data input and calculation to graphic generation and output is realized. The software has been successively applied in several projects, having realized the autonatic design of communication power.
