Rotate Example

Using Programming Languages other than VBA

Sub Example_Rotate()
	' This example creates a lightweight polyline
	' and then rotates that polyline.

	' Create the polyline
	Dim plineObj As AcadLWPolyline
	Dim points(0 To 11) As Double
	points(0) = 1: points(1) = 2
	points(2) = 1: points(3) = 3
	points(4) = 2: points(5) = 3
	points(6) = 3: points(7) = 3
	points(8) = 4: points(9) = 4
	points(10) = 4: points(11) = 2
	Set plineObj = ThisDrawing.ModelSpace.AddLightWeightPolyline(points)
	plineObj.Closed = True
	ZoomAll
		
	MsgBox "Rotate the polyline by 45 degrees.", , "Rotate Example"

	' Define the rotation
	Dim basePoint(0 To 2) As Double
	Dim rotationAngle As Double
	basePoint(0) = 4: basePoint(1) = 4.25: basePoint(2) = 0
	rotationAngle = 0.7853981   ' 45 degrees

	' Rotate the polyline
	plineObj.Rotate basePoint, rotationAngle

	ZoomAll
	MsgBox "Rotation completed.", , "Rotate Example"

End Sub
