AddLightWeightPolyline Method （ActiveX）

签名

工 务 局：

RetVal = object.AddLightWeightPolyline(VerticesList)

对象

类型：块，模型空间，图纸空间

此方法适用的对象。

顶点列表

访问：仅输入

类型：变体（双打数组）

指定折线顶点的二维 OCS 坐标数组。构造轻量级折线至少需要两个点（四个元素）。数组大小必须是 2 的倍数。

返回值（RetVal）

类型：轻量多线

新创建的对象。LightweightPolyline

言论

顶点指定构成折线的线段的端点。要添加弧段，请先创建包含所有线段的折线，然后向要成为弧的各个线段添加凸起。若要向段添加凸起值，请使用该方法。SetBulge

折线的高程将设置为布局的当前高程。使用理论属性确定折线的高程。ElevationModelspaceElevationPaperspace

可以使用该方法将坐标与OCS相互转换。TranslateCoordinates

Sub Example_AddLightWeightPolyline()
    ' This example creates a lightweight polyline in model space.
    
    Dim plineObj As AcadLWPolyline
    Dim points(0 To 9) As Double
    
    ' Define the 2D polyline points
    points(0) = 1: points(1) = 1
    points(2) = 1: points(3) = 2
    points(4) = 2: points(5) = 2
    points(6) = 3: points(7) = 2
    points(8) = 4: points(9) = 4
        
    ' Create a lightweight Polyline object in model space
    Set plineObj = ThisDrawing.ModelSpace.AddLightWeightPolyline(points)
