Hello,
I want to plot a 1-D curve in 3-D space for which I have a .vtu file which contains the 1-D mesh data including point coordinates, and their connectivity. Please find the attached .vtu file. When I select the ‘wireframe’ representation, nothing is visible, even though ‘point’ representation is working. I am wondering if I need an additional operation for this.
Thank you.

You need to generate connectivity (aka “Cells”) between your points.
You can use Delaunay3D but it will generate triangles.
There is no filter to generate lines but should be trivial to do that with a programmable filter.

Thank you very much.
My previous file had an error in the cell data’s ‘offsets’. Corrected .vtu file is attached.
