YVector プロパティ(ActiveX)

所定の UCS の Y 方向を指定します。

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.YVector

object

タイプ: UCS

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)

所定の UCS の Y 方向を指定するベクトル。

注意

アクティブな UCS で Y ベクトルの値を変更した場合は、アクティブな UCS を再設定しなければ変更結果を表示できません。 アクティブな UCS を再設定するには、ActiveUCS プロパティを使用します。

注: このプロパティの値は、システム変数 UCSYDIR に格納されます。

例

VBA:

Sub Example_YVector()
    ' This finds the current setting of YVector for a given UCS.
    ' It then changes the YVector and resets the UCS.

    Dim viewportObj As AcadViewport
    
    ' Set the viewportObj variable to the active viewport
    Set viewportObj = ThisDrawing.ActiveViewport
    
    ' Define a new UCS and turn on the UCS icon at the origin.
    Dim ucsObj As AcadUCS
    Dim origin(0 To 2) As Double
