I just tried Find Data to create a selection and then extracted it. Is the intended behavior to get rid of the cells and create a vtkPolyVertex to represent the points from the extraction? <br><br>Also, when I turned on preserve topology I get nothing which seems wrong compared to what the documentation says (If this property is set to 1 the output preserves the topology of its input and adds an insidedness array to mark which cells are inside or out. If 0 then the output is an unstructured grid which contains only the subset of cells that are inside.).<br>

<br>
I misspoke; you will need to use the development version of (i.e., the
trunk or the ParaView 3.98.1 release candidate) to extract "Find Data":
there is a fix in these newer versions for extracting selections based
on attribute values.<br>

Is that an easy way to do that ? If not, can we add a "exclude"
or "complement" box that will change the behavior of the filter
