Check the minimum thickness of the sides of a nurbs object

I’m looking for a tool to measure the minimum thickness of my objects before 3D printing!
can you help me
thanks

If you could share a 3D or an image it would help, you could use the contour command and measure there. But hard to suggest with no reference

Use PointDeviation with the inside surface as one input and the outside surface as the other input.
