Hello everyoe,  
How to find the exact diameter of the cylinder in Paraview as shown in the given screenshot. The cylinder is not uniform it keeps increasing from bottom to top and I want to find its diameter at the top.  
Thanks!

Assuming your cylinder is axis aligned, it should be easy to place a slice plane where you want to measure the diameter. The result of the slice will be a circle. Then look at the bounds in the `Information` tab. The diameter should be evident from there.
