Rotates an object around a base point.
Supported platforms: Windows only
VBA:
object.Rotate BasePoint, RotationAngle
Type: All drawing objects, AttributeReference, Dimension
The objects this method applies to.
Access: Input-only
Type: Variant (three-element array of doubles)
The 3D WCS coordinates specifying the point through which the axis of rotation is defined as parallel to the Z axis of the UCS.
Access: Input-only
Type: Double
The angle in radians to rotate the object. This angle determines how far an object rotates around the base point relative to its current location.
No return value.

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
