CAD绘制圆形云线批注（网页版）

Posted 2022-07-21 lihao2014

js中实现代码说明：

function DoCloudCircleCommentFix() 

    var comment = mxOcx.NewEntity("IMxDrawComment");

    comment.Text = "固定参数绘圆形云线标注";

    comment.TextHeight = 50;

    var frstPt = mxOcx.NewPoint();

    frstPt.x = -200;

    frstPt.y = -200;

    var basepos = mxOcx.NewPoint();

    basepos.x = 0;

    basepos.y = 10;

    var pos = mxOcx.NewPoint();

    pos.x = 200;

    pos.y = 300;

    //基点

    comment.BasePoint = basepos;

    //位置

    comment.Position = pos;

    //标注位置提示多边形的半径

    comment.ShapRadius = 50;

    //标注框类型

    comment.BoundingBoxType = 5;

    //标注箭头类型

    comment.ArrowType = 2;

    var points = mxOcx.NewComObject("IMxDrawPoints");

    points.Add2(frstPt);

    points.Add2(basepos);

    //标注框坐标数据

    comment.Bounding = points;

    var comobj = mxOcx.ObjectIdToObject(mxOcx.DrawEntity(comment));

    comobj.TextStyle = "MyCommentFont";

    mxOcx.ZoomAll();

效果展示：

通过点击绘制圆形云线标注按钮，触发DoCloudCircleCommentFix()事件，CAD控件视区将显示在js中设置好的圆形云线标注。如下图所示：
