Hello. Possibly the Slice filter with "Cylinder" and "Crinkle slice"
options will produce the required result (I checked in ParaView 5.2).

Re: [Paraview] PV4.10 extracting a surface

[Andy Bauer]

The Threshold filter works by selecting cells that have cell data in the
selected range. If you're requesting to do thresholding on a point data
array then it will use the point data to cell data filter to create a cell
data array and threshold on that. With this, it's very unlikely that any
cell data ends up with exactly a value of .1. It sounds like what you want
is to use the Contour filter on your rad array.

Re: [Paraview] PV4.10 extracting a surface

[Utkarsh Ayachit]

I believe you're getting  the warning because the threshold ended up
not producing any output. If you can attach the state/data file, I may
be able to can give more info.

Re: [Paraview] PV4.10 extracting a surface

[Stephen Wornom]

Forgot to mention that the mesh is 3D x,y,z. 
rad =sqrt( x**2+y**2) thus varies with the z-coordinate.

[Paraview] PV4.10 extracting a surface

[Stephen Wornom]

The geometry is a cylinder. 
Using the calculator I do 
rad =sqrt( x**2+y**2) 
I would like to extract the cylinder surface which is rad = 0.1 
I click on threshold then information to see rad 0.1
