例子

VBA：

Sub Example_ToleranceLowerLimit()
    ' This example creates an aligned dimension in model space and
    ' sets the tolerance limits using the ToleranceLowerLimit and
    ' ToleranceUpperLimit properties

    Dim dimObj As AcadDimAligned
    Dim newText As AcadTextStyle
    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)
    
    ' Turn on tolerance display
    dimObj.ToleranceDisplay = acTolSymmetrical
    
    ThisDrawing.Application.ZoomAll
    
    ' Read and display the tolerance limits for the dimension
    MsgBox "The tolerance lower limit is set to: " & dimObj.ToleranceLowerLimit & vbCrLf & _
           "The tolerance upper limit is set to: " & dimObj.ToleranceUpperLimit
    
    ' Adjust the tolerance limits for this dimension
    dimObj.ToleranceLowerLimit = 0.0001
    dimObj.ToleranceUpperLimit = 0.005
    
    ThisDrawing.Regen acAllViewports
    
    ' Read and display the tolerance limits for the dimension
    MsgBox "The tolerance lower limit is now set to: " & dimObj.ToleranceLowerLimit & vbCrLf & _
           "The tolerance upper limit is now set to: " & dimObj.ToleranceUpperLimit
