绘制等距网格

快捷标注多段线点号坐标，快捷查看封闭区域面积，单位亩、平方米等，加载lsp至cad即可使用(Quick Note polyline dot coordinates, quick check enclosed area of ​ ​ the unit acres, square, etc., can be used to load lsp to cad)

cad的lisp文件，pwx根据三点坐标生成抛物线，xyz收集点的坐标(cad lisp files generated, according to the coordinates of three parabolic)

说明：  把AutoCAD的VLX文件反编译成FAS文件(Decompiles VLX files of AutoCAD into FAS files)

CAD下line或pline线与对应轴线间距离取整程序，对于该线与轴线间距离为碎尺寸时非常有用。(Line or pline between axis distance corresponding rounded program for the inter-line distance is useful when the axis is broken dimensions.)

MATLAB赋值，获取最大值，及其最小值到等！(MATLAB assignment, obtain the maximum)

cad中可以像cass一样划线,具有换向，隔点闭合等功能！(cad cass huaxian)

加载影像图,并按照坐标加载到底图中.........(Load the image map and load it in accordance with the coordinates.)
