CAD drawing diameter dimension parameter (com interface)

The main use of Function:

_DMxDrawX::DrawDimDiametric

Draw a diameter dimension. Details are as follows:

parameter	Explanation
DOUBLE dChordPointX	The first point is marked on the X value curve
DOUBLE dChordPointY	The first point is marked on the Y value curve
DOUBLE dFarChordPointX	On the curve labeled second point value X, the diametrically opposite point chordPoint
DOUBLE dFarChordPointY	The second point on the Y value of the curve is marked, the diametrically opposite point chordPoint
DOUBLE dLeaderLength	Input arrows length

Implemented in C # code description:

private void DrawDimDiametric()
{
    axMxDrawX1.AddDimStyle("MyDimStyle", "41,0.18,141,0.09,40,200", "77,1,271,3", "", "");
    axMxDrawX1.DimStyle = "MyDimStyle";
    //把颜色改回黑白色
    axMxDrawX1.DrawCADColor = 0;
    //把线型改成实线
    axMxDrawX1.LineType = "";
    //设置线宽 4
    axMxDrawX1.LineWidth = 0;
    //绘制一个直径标注
    //参数一为在被标注的曲线上的第一个点X值 ，参数二为在被标注的曲线上的第一个点Y值
    //参数三为在被标注的曲线上的第二个点X值，这个点与chordPoint直径相对
    //参数四为在被标注的曲线上的第二个点Y值，这个点与chordPoint直径相对
    //参数五为输入箭头长度
    axMxDrawX1.DrawDimDiametric(50, 570, 60, 600, 100);
    //把所有的实体都放到当前显示视区
    axMxDrawX1.ZoomAll();
    //更新视区显示
    axMxDrawX1.UpdateDisplay();
}
