摘要
为适应机械CAD软件中变参数高效、自动绘制剖面图的需要。本文在对AutoCAD绘图软件包中HATCH指令的功能完善方面作了一些尝试性的工作，得到机械图剖面线剖制通用程序，其运行情况令人满意。
To improve the function of the command 'HATCH' used in Auto CAD software (10.0-11.0) for filling section zone,the author developed a commonlly used program for filling sectional zone of the mechanical section drawing.It is shown that the algorithm and program is efficient and convenient in practical.
