TextGap 属性（ActiveX）

指定在分割尺寸线以容纳尺寸文本时尺寸文本与尺寸线之间的距离。

支持的平台：仅限 Windows

签名

VBA：

object.TextGap

对象

类型：Dim3PointAngular、DimAligned、DimAngular、DimArcLength、DimDiametric、Dimension、DimOrdinate、DimRadial 、DimRadialLarge、DimRotated、Leader

此属性应用于的对象。

属性值

只读：不

类型：双

指定间隙距离的实数。

言论

此属性还设置对象上的批注和挂钩线之间的间隙。Leader

负值创建基本尺寸标注（文本周围带有框的尺寸文本）。

注意：此属性将覆盖给定维度的 DIMGAP 系统变量的值。

例子

VBA：

Sub Example_TextGap()
   ' This example creates an aligned dimension in model space and
   ' uses the TextGap property to increase the distance between the
   ' dimension line and the dimension text

    Dim dimObj As AcadDimAligned
    Dim point1(0 To 2) As Double, point2(0 To 2) As Double
    Dim location(0 To 2) As Double
    
    ' Define the dimension
    point1(0) = 5: point1(1) = 5: point1(2) = 0
    point2(0) = 5.5: point2(1) = 5: point2(2) = 0
    location(0) = 5: location(1) = 7: location(2) = 0
    
    ' Create an aligned dimension object in model space
    Set dimObj = ThisDrawing.ModelSpace.AddDimAligned(point1, point2, location)
    ThisDrawing.Application.ZoomAll

    ' Read and display current dimension gap
    MsgBox "The dimension gap for this object is currently set to: " & dimObj.TextGap

    ' Increase the distance of the dimension gap
    dimObj.TextGap = 0.5
    ThisDrawing.Regen acAllViewports
    
    ' Read and display current dimension gap
    MsgBox "The dimension gap for this object is now set to: " & dimObj.TextGap
    
End Sub
