プロパティの値

読み込み専用: いいえ

タイプ: Layout および PlotConfiguration オブジェクトに対してバリアント型(3 要素の倍精度浮動小数点数型配列)またはバリアント型(2 要素の倍精度浮動小数点数型配列)

3D Point: オブジェクトの原点を表す 3D WCS 座標。

例

VBA:

Sub Example_Origin()
    ' This example creates a UCS and returns its origin.

    Dim viewportObj As AcadViewport
    
    ' Set the viewportObj variable to the activeviewport
    Set viewportObj = ThisDrawing.ActiveViewport
    
    ' Create a new UCS with origin 2, 2, 0
    Dim ucsObj As AcadUCS

    MsgBox "The origin of the UCS is: " & ucsObj.origin(0) & ", " & ucsObj.origin(1) & ", " & ucsObj.origin(2), , "Origin Example"

    ' Change the origin of the UCS
    origin(0) = 4: origin(1) = 4: origin(2) = 0
    ucsObj.origin = origin
    
    ' Reset the active UCS and viewport to see the change

    MsgBox "The origin of the UCS is now: " & ucsObj.origin(0) & ", " & ucsObj.origin(1) & ", " & ucsObj.origin(2), , "Origin Example"
