STUDY ON THE AUTOMATICAL DRAWING OFLONGITUDE-LATITUDE FRAME ON TRAPEZE

This paper presents a method which calculates automatically parameters for longitude-latitude frame accgrding to the trapeze sheet number. On the basis of Turboc and AutoCAD drawingsoftware, the module of drawing longitude-latitude frame is developed. Inputtins only normal sheetnumber, the module, which is developed,can automatically generate drawing data file (*.SCR) ofdrawing longitude-latitude frame under AutoCAD. The module has also ability of detecting error ofthe sheet number.
