• True: The attribute is an invisible attribute.

Examples

VBA:

Sub Example_Invisible()
    ' This example creates an attribute definition in model space.
    ' It then queries the visibility of the attribute, changes
    ' the visibility, and queries the visibility again.
    
    Dim attributeObj As AcadAttribute
    Dim height As Double
    Dim mode As Long
    Dim prompt As String
    Dim insertionPoint(0 To 2) As Double
    Dim tag As String
    Dim value As String
    
    ' Define the attribute definition
    height = 1#
    mode = acAttributeModeVerify
    prompt = "New Prompt"
    insertionPoint(0) = 5#: insertionPoint(1) = 5#: insertionPoint(2) = 0
    tag = "New_Tag"
    value = "New Value"
    
    ' Create the attribute definition object in model space
    Set attributeObj = ThisDrawing.ModelSpace.AddAttribute(height, mode, prompt, insertionPoint, tag, value)
    ZoomAll
    
    ' Find the current visibility for the attribute
    GoSub QUERYSTATUS
        
    ' Change the visibility of the attribute
    attributeObj.Invisible = Not attributeObj.Invisible
    ZoomAll
    
    GoSub QUERYSTATUS
    
    Exit Sub
    
QUERYSTATUS:
    If attributeObj.Invisible Then
        MsgBox "The attribute is invisible."
    Else
        MsgBox "The attribute is visible."
    End If
    Return
End Sub
