Zhizhen Liu · Journal of Shandong University of Technology · 2003
With the help of the object oriented programming environment, strong calculating and developing ability of VBA technology and the abundant graphics processing function of AutoCAD, VBA has become an in-line controller and can share memory data such as data of Microsoft office software with AutoCAD. By setting the macro attributes of VBA, this technology is introduced into the drawing process of transformer core laminations in a transformer design. The formulae of the step thickness and angle in polar coordinate system are derived.By applying VBA technology in the data process for the transformer core, the result data are saved in the EXCEL data-base, which can be modified, inquired and added. The drawing of core laminations for a practical transformer is finished consequently.
