Well, this logic had come in my mind.. but in this case, i need to delete existing two vtkContourWidgets objects<br>and then create a new one.. For this i have to manipulate the list of vtkContourWidgets objects..<br>Thus i thought better to first find out is there any other possibility to get this done..<br>

Get the output of the two contours, it will be in vtkPolyData type and use append filter and then display it. You can use addObservers to make it interactive.<br><br>Jothy<br><br><div class="gmail_quote">On Thu, Jul 22, 2010 at 5:03 PM, Rakesh Patil <span dir="ltr"><<a href="mailto:rakeshthp@in.com" target="_blank">rakeshthp@in.com</a>></span> wrote:<br>
