Rotate3D メソッド(ActiveX)

3 次元の軸を中心にして、オブジェクトを回転させます。Point1 と Point2 によって、回転軸の線分を定義します。

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.Rotate3D Point1, Point2, RotationAngle

object

タイプ: すべての図形オブジェクト、AttributeReference、Dimension

このメソッドが適用されるオブジェクト。

戻り値はありません。

注意

例

VBA:

Sub Example_Rotate3D()
    ' This example creates a box in model space.
    ' It then rotates the box about an axis.
        
    Dim boxObj As Acad3DSolid
    Dim length As Double, width As Double, height As Double
    Dim center(0 To 2) As Double
    
    ' Define the box
    center(0) = 5#: center(1) = 5#: center(2) = 0
    length = 5#: width = 7: height = 10#
    
    ' Create the box (3DSolid) object in model space
    Set boxObj = ThisDrawing.ModelSpace.AddBox(center, length, width, height)
    
    ' Change the viewing direction of the viewport
    Dim NewDirection(0 To 2) As Double
    NewDirection(0) = -1: NewDirection(1) = -1: NewDirection(2) = 1
    ThisDrawing.ActiveViewport.direction = NewDirection
    ThisDrawing.ActiveViewport = ThisDrawing.ActiveViewport
    ThisDrawing.Regen True
        
    ' Define the rotation axis with two points
    Dim rotatePt1(0 To 2) As Double
    Dim rotatePt2(0 To 2) As Double
    Dim rotateAngle As Double
    
    rotatePt1(0) = -3: rotatePt1(1) = 4: rotatePt1(2) = 0
    rotatePt2(0) = -3: rotatePt2(1) = -4: rotatePt2(2) = 0
    rotateAngle = 30
    rotateAngle = rotateAngle * 3.141592 / 180#
    
    ' Draw a line between the two axis points so that it is visible.
    ' This is optional. It is not required for the rotation.
    Dim axisLine As AcadLine
    Set axisLine = ThisDrawing.ModelSpace.AddLine(rotatePt1, rotatePt2)
    axisLine.Update
    MsgBox "Rotate the box 30 degrees about the axis shown.", , "Rotate3D Example"

    ' Rotate the box
    boxObj.Rotate3D rotatePt1, rotatePt2, rotateAngle
    ThisDrawing.Regen True
    MsgBox "The box is rotated 30 degrees.", , "Rotate3D Example"
    
End Sub
