CAD 精简多段线顶点——cad c# 二次开发

效果如下：

 部分代码如下（须完善）：

    public static void DD()
    {
        using var tr = new DBTrans();
       
        // CreateSimplePolyline3d();
        //*****polyline2d转polyline开始
        //tr.Editor.GetEntities<Polyline2d>(out List<Polyline2d> mypl2d, "\n请选择polyline2d\n");
        //Polyline2dToPolyline(tr, mypl2d[0]);
        //*****polyline2d转polyline结束
        //if (!tr.Editor.GetEntities<Curve>(out List<Curve> mycur, "")) return;
        //tr.Database.CurvesToPolyLine(mycur);//手画一个椭圆，转为多段线
        if (!tr.Editor.GetEntities<Polyline>(out List<Polyline> mypl, "\n选择polyline")) return;
        var resultPl = SimplifyPolylines(mypl, 5);
        //resultPl[0].ColorIndex = 1;
        tr.ModelSpace.AddEntity(resultPl);
    }
