[vtkusers] Boolean Operation to create a hollow cylinder

[dvmorris]

I would really like to create a pipe, or a ring if that makes sense. It looks
like it can be done with a combination of clipping planes and implicit
cylinders, but I'm not sure I know how to do that properly, I just wanted to
see if anyone had any example of that out there before I started trying out
different methods.

Here is an example of what I would like to be able to create:

Thanks for the quick replies,

Dave
