Distance of a point to a surface

Dear cummunity,

I am using Paraview 5.12.0 and want to calculate the orthogonal distance of a point to a surface. At the moment I am using a Ruler and visually check whether the seond point of the Ruler makes a perpendicular line to the surface or not. The following fig shows what I mean:

However, it is not accurate. Is there a way to find the distance between point and closet node of the surface? I guess it will be the orthogonal distance between the point and the surface. The surface is named as fault and is one of the blocks of my mesh.
In advance I appreciate any help.

I don’t think such a widget exist, however it would be a nice addition!
