I’ve got a set of curves in space that follow a tube-like pattern, and I want to connect the lines with surfaces to create a solid walled tube. After some investigation, I found the RuledSurfaceFilter in VTK, but was disappointed to see that it isn’t on the list of Paraview filters accessible in the GUI. I worked out a python script to load in my curves, apply the RuledSurfaceFilter, and plot the surface in a vtk renderer.[ManifoldSurface.py](https://discourse.paraview.org/uploads/short-url/rfn9M8NG33K5ra3FnKt4C6ZUR3N.py) (2.2 KB) However, I was wondering if there’s a way to export this surface into Paraview so I can work on smoothing it out and plotting other things with it.

Thanks,  
Jared

Here is an example that writes out a vtp file that can be used in ParaView: [RuledSurfaceFilter.py](https://discourse.paraview.org/uploads/short-url/tlhVWmvY6gXdjTKwznCK7OdjWSi.py) (2.5 KB).

It is based on [RuledSurfaceFilter](https://lorensen.github.io/VTKExamples/site/Python/PolyData/RuledSurfaceFilter/), please note that this VTK Examples site is no longer being updated. A new site is coming soon.

Perfect, this was exactly what I needed. Thank you!
