How can I create a group of 1 edge every 3 edges?

[Masoud]

Hi guys,

How can I create a group of edges by range same as the "Group By Range" SOP, (I mean procedurally) : for example 1 edge every 3 edges?

 

Thanks for helping.

Hi Sunchao360,
Thank you for the reply, but I didn't get your solution 

[konstantin magnus]

you could promote a group from polygons to edges.

Thank you Konstantin, but your solution a little bit complicated.
I tried to use the "neighbours()" VEX function to set the edges group:

int nei[];
i[]@nei = neighbours(0, @ptnum);        

foreach(int i; @nei)
{
    if (inpointgroup(0, chs("group"), i))
    {
        setedgegroup(0, "SelectedEdges", @ptnum, i, 1);
    }
}

And here is my hip file:
