Hello,
Noobie question here, I try to make a procedural fence but polybevel won't work on my line. I try the convert node but it doesn't help. Here is a screen of my workspace, it maybe help :

I made two lines, group 2 points, connect them with add, and add another group of all the points, then the polybevel.
What am I doint wrong? I don't understand why the polybevel work on curves but not on a line made of points.

Looks more like you have 3 lines. I think the poly bevel requires the shape to be a single line, rather than multiple disconnected lines.

Ok, so how could I make it one line ?
Are you sure it's 3 lines? In this case I should have 6 points instead of 4 I think.

Nope, 3 lines can share points and so still have just 4 points.

In your case, the simplest way to build a single curve from the segments is with either a join or polypath sop.

Edit:
The join sop does not remove redundant vertices.

Work perfeclty, thanks a lot sir !
