Hi,
Is it possible to visualize the “curved” edges of a mesh composed of quadratic edges?
I tried to increase the `Nonlinear Subdivision Level` but nothing changes. With a “volumic” mesh, this settings seems to work well (tested on the file mentioned [here](https://gitlab.kitware.com/paraview/paraview/-/issues/17597)). But on my “lineic” mesh I would say, I doesn’t work. See the attached file.
Thank you!

Try using the `Tessellate` filter

Perfect, thank you Greg.
