Thanks you very much. I will try that. I thought normals might be needed for filling holes and not for writing a ply file. thanks again.<br><br><div class="gmail_quote">On Thu, Mar 21, 2013 at 7:42 PM, David Gobbi [via VTK] <span dir="ltr"><<a href="/user/SendEmail.jtp?type=node&node=5719540&i=0" target="_top" rel="nofollow" link="external">[hidden email]</a>></span> wrote:<br>

Hi Guarav,
<br><br>If vtkFillHolesFilter is causing the inconsistent faces, right? So if
<br>vtkPolyDataNormals is supposed to fix the problem, doesn't it make
<br>more sense to put it after FillHoles, instead of before?
<br><br>Also, as I said in my first email, Consistency is an _option_ for
<br>vtkPolyDataNormals. That means you need SetConsistency(1) in
<br>order for it to take effect.
<br><br>I hope this helps.
