言论

此属性的初始值为。acLnWtByBlock

线宽值由标准设置组成，包括 BYLAYER、BYBLOCK 和 DEFAULT。DEFAULT 值由 LWDEFAULT 系统变量设置，默认值为 0.01 in。或 0.25 毫米。所有新对象和图层的默认设置均为 DEFAULT。线宽值 0 以指定绘图设备上可用的最细线宽绘制，并在模型空间中以 1 个像素宽显示。

例子

VBA：

Sub Example_LineWeight()
    ' This example creates a circle in model space and then
    ' finds the current lineweight for the circle. The lineweight
    ' is then changed to a new value.
   
    Dim circleObj As AcadCircle
    Dim centerPoint(0 To 2) As Double
    Dim radius As Double
    
    ' Define the circle
    centerPoint(0) = 0#: centerPoint(1) = 0#: centerPoint(2) = 0#
    radius = 5#
    
    ' Create the Circle object in model space
    Set circleObj = ThisDrawing.ModelSpace.AddCircle(centerPoint, radius)
    ZoomAll
    
    ' Find the lineweight for the circle
    MsgBox "The current lineweight for the circle is " & circleObj.Lineweight
    
    ' Change the lineweight for the circle
    circleObj.Lineweight = acLnWt211
    circleObj.Update
    MsgBox "The current lineweight for the circle is " & circleObj.Lineweight
End Sub
