半径寸法および直径寸法の中心マークのタイプを指定します。

サポートされているプラットフォーム: Windows のみ

構文と要素

VBA:

object.CenterType

object

タイプ: DimDiametric、DimRadial、DimRadialLarge

このプロパティが適用されるオブジェクト。

プロパティの値

読み込み専用: いいえ

タイプ: acDimCenterType 列挙型

• acCenterMark
• acCenterLine
• acCenterNone

注意

中心マークは寸法線を円または円弧の外側に配置した場合にのみ表示されます。

注: このプロパティは、指定された寸法でシステム変数 DIMCEN[中心サイズ]の値を変更します。

例

VBA:

Sub Example_CenterType()
    ' This example creates a diametric dimension in model space.
    ' It then changes the type of center for the dimension.
    
    Dim dimObj As AcadDimDiametric
    Dim chordPoint(0 To 2) As Double
    Dim farChordPoint(0 To 2) As Double
    Dim leaderLength As Double
    
    ' Define the dimension
    chordPoint(0) = 5#: chordPoint(1) = 3#: chordPoint(2) = 0#
    farChordPoint(0) = 5#: farChordPoint(1) = 5#: farChordPoint(2) = 0#
    leaderLength = 1#
    
    ' Create the diametric dimension in model space
    Set dimObj = ThisDrawing.ModelSpace.AddDimDiametric(chordPoint, farChordPoint, leaderLength)
    ZoomAll
    
    ' Set the center to be none
    dimObj.CenterType = acCenterNone
    dimObj.Update
    MsgBox "The dimension center type is set to none."
    
    ' Change the center type to center mark
    dimObj.CenterType = acCenterMark
    dimObj.Update
    MsgBox "The dimension center type is set to center mark."
    
    ' Change the center type to center line
    dimObj.CenterType = acCenterLine
    dimObj.Update
    MsgBox "The dimension center type is set to center line."
End Sub
