尺寸的标注: 本例实现如下功能：在二维工程图中指定的坐标处创建并显示由引出线引出的文本。 -Size marked: in this case to achieve the following functions: two-dimensional drawings created in the specified coordinates and displays the text from the Lead-out leads.

在测量绘图中添加坐标、大小坐标转换、显示和隐藏等快捷功能。-Added in the surveying and mapping coordinates, the size of the coordinate conversion, display, and hidden shortcut feature.

在AUTOCAD中将选的二维多段线每个转折点坐标依次显示出来，去掉“于端点，X＝，Y＝”等多余符号，可复制后方便复制到EXCEL中。-Will be selected in AUTOCAD 2D polylines each point of coordinates sequentially displayed, remove in the end, X , Y and other redundant symbols can copy after copy easy to EXCEL

该cad插件可以提取dwg文件管线信息，并直接生成swmm模型可读取的inp文件。 提取的管线信息包括管长、管径、标高、坐标、上下游拓扑关系等； 生成inp文件，可直接拖入swmm中显示。包含[OUTFALLS]，[JUNCTIONS]，[CONDUITS]，[XSECTIONS]，[COORDINATES]，[VERTICES]部分(The CAD plug-in can extract DWG file pipeline information and directly generate
