AltToleranceSuppressLeadingZeros Property (ActiveX)

Specifies the suppression of leading zeros in alternate dimension values.

Supported platforms: Windows only

Signature

VBA:

object.AltToleranceSuppressLeadingZeros

object

Type: DimAligned, DimArcLength, DimDiametric, DimOrdinate, DimRadial, DimRadialLarge, DimRotated

The objects this property applies to.

Property Value

Read-only: No

Type: Boolean

• True: Suppress leading zeros in alternate dimensions. For example, 0.5000 becomes .5000.
• False: Do not suppress leading zeros in alternate dimensions.

Remarks

The initial value for this property is False.

Note: This property overrides the value for the DIMALTTZ system variable for the given dimension.

Examples

VBA:

Sub Example_AltToleranceSuppressLeadingZeros()
   ' This example creates an aligned dimension in model space and
   ' uses AltToleranceSuppressLeadingZeros to toggle the display of leading zeros
   ' in the alternate dimension tolerance display

    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) = 5.01: 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)
    
    ' Set up alternate unit tolerance display
    dimObj.AltUnits = True
    dimObj.ToleranceDisplay = acTolLimits
    
    ThisDrawing.Application.ZoomAll
    
Toggle:
    Select Case MsgBox("Press OK to toggle the display of leading zeros in the alternate dimension tolerance", vbOKCancel)
        Case vbOK
            ' Toggle the display of leading zeros for the alternate dimension tolerance value
            dimObj.AltToleranceSuppressLeadingZeros = Not (dimObj.AltToleranceSuppressLeadingZeros)
            ThisDrawing.Regen acAllViewports
        Case vbCancel
            Exit Sub
    End Select
    
    GoTo Toggle
End Sub
