ExtLine2StartPoint プロパティ(ActiveX)

第 2 寸法補助線の始点を指定します。

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.ExtLine2StartPoint

object

タイプ: DimAngular

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: バリアント型(倍精度実数の 3 要素配列)

2 番目の寸法補助線の始点の 3D 座標

注意

ExtLine1StartPoint と ExtLine2StartPoint プロパティは、AddDimAngular における FirstEndPoint と SecondEndPoint パラメータと同じです。寸法補助線は、最初は FirstEndPoint と SecondEndPoint の位置から寸法線の交点に引かれます。AutoCAD は、寸法線を寸法補助線間にかかる円弧として描きます。

例

VBA:

Sub Example_ExtLine2StartPoint()
    ' This example creates an angular dimension. It then changes
    ' the location of the ExtLine2StartPoint.
    
    Dim dimObj As AcadDimAngular
    Dim angVert(0 To 2) As Double
    Dim FirstPoint(0 To 2) As Double
    Dim SecondPoint(0 To 2) As Double
    Dim TextPoint(0 To 2) As Double
    
    ' Define the dimension
    angVert(0) = 0#: angVert(1) = 5#: angVert(2) = 0#
    FirstPoint(0) = 1#: FirstPoint(1) = 7#: FirstPoint(2) = 0#
    SecondPoint(0) = 1#: SecondPoint(1) = 3#: SecondPoint(2) = 0#
    TextPoint(0) = 3#: TextPoint(1) = 5#: TextPoint(2) = 0#
    
    ' Create the angular dimension in model space
    Set dimObj = ThisDrawing.ModelSpace.AddDimAngular(angVert, FirstPoint, SecondPoint, TextPoint)
    ZoomAll
    MsgBox "The current value of ExtLine2StartPoint is " & dimObj.ExtLine2StartPoint(0) & ", " & dimObj.ExtLine2StartPoint(1) & ", " & dimObj.ExtLine2StartPoint(2), vbInformation, "ExtLine2StartPoint Example"
    
    ' Change the start point of the second extension line
    FirstPoint(0) = 1: FirstPoint(1) = 4: FirstPoint(2) = 0
    dimObj.ExtLine2StartPoint = FirstPoint
    dimObj.Update
    
    ' Return the start point of the second extension line
    ' Note that the return value is a Variant
    Dim retPnt As Variant
    retPnt = dimObj.ExtLine2StartPoint
    MsgBox "The new value of ExtLine2StartPoint is " & dimObj.ExtLine2StartPoint(0) & ", " & dimObj.ExtLine2StartPoint(1) & ", " & dimObj.ExtLine2StartPoint(2), vbInformation, "ExtLine2StartPoint Example"
End Sub
