The upper method takes the current transormation and applies the new one to the obj.transformation w/o any global variables. If you apply an global variable as transformation the reference will be stored inside the obj.transformation and this results in an behavior like you describe. Are you using VB?

yes VB.
I try to follow the example but nothing... when i apply transformation on the second obj also the first is moved...  i'm getting crazy!
Here is my code:

Code:

sub createcontrol(numdente1)


  Dim  mymodelrotator As New ModelRotatorVisual3D
  mymodelrotator.Position = pointcenter
  mymodelrotator.Transform = mygroupx
  mymodelrotator.InnerRadius = 10
  mymodelrotator.OuterRadius = 10.3
  mymodelrotator.CircleWidth = 0.3
  AddHandler mymodelrotator.ModelRotateStarted, AddressOf started
  AddHandler mymodelrotator.ModelRotated, AddressOf rotated
  AddHandler mymodelrotator.ModelRotateEnded, AddressOf endrotate
  _EventManager3D.RegisterEventSource3D(visualEvent)
End sub

Sub started(sender As Object, args As ModelRotatedEventArgs)
       _startRotate.Angle = args.RotationAngle
       Dim rotatetransform As New RotateTransform3D(_startRotate)
       addtransform(dentehit.visualhit, rotatetransform)
End Sub
Sub rotated(sender As Object, args As ModelRotatedEventArgs)



   
       _startRotate.Angle = args.RotationAngle

End sub


 Sub addtransform(myvisual As Visual3D, mytransform As Transform3D)
       If myvisual.Transform Is Nothing Then
           myvisual.Transform = mytransform
       End If


       Dim transformgroup As New Transform3DGroup


       transformgroup.Children.Add(myvisual.Transform)
       myvisual.Transform = transformgroup


       transformgroup.Children.Add(mytransform)


   End Sub
