Hi! I been using Paraview for some time (i.e. not beginner).

I wonder if it is possible to extrude a simple 3D line (a VTK\_LINE = 3), into a cylinder. This is because the line have “vectors” on ends, and therefore moves (animated) when applying Warp By Vector.

I want to go from left to right in 1 step.

Thank you. I need to apply “Extract Surface” every time, but it works!

Recently, I’ve been asking those types of questions to ChatGPT. It does a good job of finding the right algorithm.
