绘图程序的初始化处理，记录当前层名、线型、颜色、捕捉方式、文本样式、文本高度,

控制点标记可见方式、主单位值消零处理方式、命令行回显方式、然后关闭目标捕捉, 设置线形随层、颜色随层、设置命令行不回显、不显示控制点标记、对主单位值后续零作消零处理-Mapping of the initialization procedure processing, recording the current layer name, line, color, capture mode, text style, text height, control points can be seen marking the way, the main consumer unit value approach zero, the command line echo, and then shut down the target capture, set up with the story line, color, with the layer settings do not echo the command line does not show the control points marked on the main unit of value for follow-up to eliminate zero-zero deal
