Problems piping a catenary curve

Hi there!

I am trying to pipe several catenary curves but there seems to be small gaps of the curve where the pipe doesn’t go through.

Does anyone know what the problem may be? (13.0 KB)

Notice how the pipes have overlapping segments, I guess that the polyline length between segments might be too short for the pipe to work properly.

I have converted the polylines to polycurves and it seems to work a better:

Here’s a modified version that I’m working on for 3D printing. I’ve not tried anything with catenary curves before; thanks to sagetojh for showing how they work. (27.6 KB)
