<div dir="ltr">The easiest fix to this is to copy vtkPVGeometryFilter from ParaView into your project and then use that. Eventually, we should migrate that to VTK and deprecate some of the other ones to clean things up but it hasn't been a priority so far.</div>

<p class="MsoNormal">I have a strange issue and I’m not sure if it is my data or a limitation I wasn’t aware of.<u></u><u></u></p>
