ブロックまたは外部参照内の一定属性を取得します。
サポートされているプラットフォーム: Windows のみ
VBA:
RetVal = object.GetConstantAttributes
タイプ: BlockReference、ExternalReference、MInsertBlock
このメソッドが適用されるオブジェクト。
GetConstantAttributes メソッドは、ブロックまたは外部参照に付加された一定属性の配列を戻します。戻った属性は一定属性定義です。属性参照ではありません。
VBA:
Sub Example_GetConstantAttributes() ' This example creates a constant attribute definition on a block. ' It then queries the block to return the attribute. ' Create the block to hold the attribute Dim blockObj As AcadBlock Dim insertionPnt(0 To 2) As Double insertionPnt(0) = 0#: insertionPnt(1) = 0#: insertionPnt(2) = 0# Set blockObj = ThisDrawing.Blocks.Add(insertionPnt, "New_Block") ' Define the attribute definition Dim attributeObj As AcadAttribute Dim height As Double Dim mode As Long Dim prompt As String Dim tag As String Dim value As String height = 1# mode = acAttributeModeConstant prompt = "Constant Prompt" insertionPnt(0) = 5#: insertionPnt(1) = 5#: insertionPnt(2) = 0# tag = "Constant_Tag" value = "Constant Value" ' Create the attribute definition object on the block Set attributeObj = blockObj.AddAttribute(height, mode, prompt, insertionPnt, tag, value) ZoomAll ' Insert the block into the drawing Dim blockRefObj As AcadBlockReference insertionPnt(0) = 2#: insertionPnt(1) = 2#: insertionPnt(2) = 0 Set blockRefObj = ThisDrawing.ModelSpace.InsertBlock(insertionPnt, "New_Block", 1#, 1#, 1#, 0) ' Get the constant attribute definition from the block Dim queryAttribute As Variant queryAttribute = blockRefObj.GetConstantAttributes Dim count As Integer count = UBound(queryAttribute) - LBound(queryAttribute) MsgBox "The block reference has " & count & " constant attributes."
