2024-5-18 18:46| 发布者: admin| 查看: 306| 评论: 0|原作者: admin|来自: AutoCAD

指定 2D AutoCAD 对象在其高程上方或下方拉伸的距离。

支持的平台：仅限 Windows

签名

VBA：

object.Thickness

对象

类型：圆弧、属性、属性参照、圆、线、LWPolyline、点、折线、形状、实体、文本、迹线

此属性应用于的对象。

属性值

只读：不

类型：双

默认值为 0.0。

言论

更改对象的厚度会更改其 Z 方向厚度。

更改 3D 折线、尺寸或浮动视口的粗细不起作用。

例子

VBA：

Sub Example_Thickness()
    ' This example creates a circle in model space
    ' and changes the thickness of the circle.
   
    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 current thickness of the circle
    Dim currThickness As Double
    currThickness = circleObj.Thickness
    MsgBox "The thickness of the circle is " & circleObj.Thickness, vbInformation, "Thickness Example"
    
    ' Change the thickness of the circle
    circleObj.Thickness = currThickness + 3
    circleObj.Update
    
    ' Change the direction of the viewport so that you can
    ' view the change made to the thickness. Once you change
    ' the direction, you must reset the active viewport.
    Dim NewDirection(0 To 2) As Double
    NewDirection(0) = -1: NewDirection(1) = -1: NewDirection(2) = 1
    ThisDrawing.ActiveViewport.direction = NewDirection
    ThisDrawing.ActiveViewport = ThisDrawing.ActiveViewport
    MsgBox "The thickness of the circle is now " & circleObj.Thickness, vbInformation, "Thickness Example"
    
End Sub
