Nautilus Generate single line path useful for 3d printing

Hello everyone,

I try to create a single line path for 3d printing concrete and am working with the Nautilus plugin. How do I use the Join Closed Curves Stacked node correctly.
In general I’m only getting closed curves and I need an open curve to get the slicer working properly.

Thank you
Michael

Hello
you will find an example here

Thank you just what I was looking for.

Is there a way to get a smoother transition from one layer to the other instead of stepwise function?

Hello
for sure there are other ways. I implemented this one because for some tools it is better to stay parallel. But sometime you would need a continuous move. Here an example for making that from some continuous curves. I am not sure it is will work 100% but you get the idea.

And a more generic one that will work on more curves type (closed), I used a smooth polyline to smooth the transition.

A better way is to slice the shape with an helix and not a plane but I have no tool for that. It is not complex to do it for simple shape like that. You throw a ray using an helix then you get the points.
