主要用到函数说明:

_DMxDrawX::DrawDimRadial

绘制一个半径标注。详细说明如下:

DOUBLE dCenterX

被标注的曲线的中点X值

DOUBLE dCenterY

被标注的曲线的中点Y值

DOUBLE dChordPointX

被标注的曲线上的点X值

DOUBLE dChordPointY

被标注的曲线上的点Y值

DOUBLE dLeaderLength

输入箭头长度

MxDrawX1.DrawDimRadial 500, 6600, 500, 6650, 0
 
'把所有的实体都放到当前显示视区
MxDrawX1.ZoomAll
 
'更新视区显示
MxDrawX1.UpdateDisplay
