SnapRotationAngle プロパティ(ActiveX)

ビューポートのスナップの回転角度を、現在の UCS で指定します。

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.SnapRotationAngle

object

タイプ: PViewport、Viewport

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: 倍精度浮動小数点数型

ラジアンで表した角度有効範囲は 0～2π

注意

アクティブなペーパー空間のビューポートに対して、スナップ基点を変更することはできません。

このプロパティへの変更は、Update または Regen を実行するまで画面に反映されません。

注: このプロパティの値は、システム変数 SNAPANG に格納されます。

例

VBA:

Sub Example_SnapRotationAngle()
    ' This example changes the snap rotation angle for a
    ' model space and paper space viewport.
    
    ' Create a new model space viewport
    Dim viewportObj As AcadViewport
    Set viewportObj = ThisDrawing.Viewports.Add("NewViewport")
    
    ' Find the current snap rotation angle
    Dim currSnapAngle As Double
    currSnapAngle = viewportObj.SnapRotationAngle
    MsgBox "The current model space snap rotation angle is " & viewportObj.SnapRotationAngle, , "SnapRotationAngle Example"
    
    ' Change the snap rotation angle
    viewportObj.SnapRotationAngle = 1.5
    MsgBox "The new model space snap rotation angle is " & viewportObj.SnapRotationAngle, , "SnapRotationAngle Example"
    
    ' Create a new paper space viewport
    Dim pviewportObj As AcadPViewport
    Dim center(0 To 2) As Double
    Dim width As Double
    Dim height As Double
    
    center(0) = 3: center(1) = 3: center(2) = 0
    width = 40
    height = 40
    ThisDrawing.ActiveSpace = acPaperSpace
    Set pviewportObj = ThisDrawing.PaperSpace.AddPViewport(center, width, height)
    
    ' Find the current snap rotation angle
    currSnapAngle = pviewportObj.SnapRotationAngle
    MsgBox "The current paper space snap rotation angle is " & pviewportObj.SnapRotationAngle, , "SnapRotationAngle Example"
    
    ' Change the snap rotation angle
    pviewportObj.SnapRotationAngle = 1.5
    MsgBox "The new paper space snap base point is " & pviewportObj.SnapRotationAngle, , "SnapRotationAngle Example"
