[Paraview-developers] The Threshold filter

[David Thompson]

Hi Andy,

> 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? 

When you select points, then yes. There should be a checkbox to select cells with points that match a criterion if you wish to preserve the cells.

> Also, when I turned on preserve topology I get nothing ...

I have not fiddled with Preserve Topology so I can't speak to what's right or wrong there.
