hi, I have bunch of spheres, and then scatter points on them. next I want to do is to connect those points to lines, I mean getting each point from two sphere.
like this picture shows:

One solution could be
1)Use foreach operator to work on every sphere
2)Scatter points (You can randomize this if you want) on every sphere inside foreach.
3)Add attrb, say sortno with value == $PT inside foreach
4)After foreach, connect add sop > By Group > Add - By Attribute - sortno it will connect all the points with similar sortno value.
5)If you dont want all the points to be connected, create different groups  of points on the any two (or any number of spheres you want) spheres , process these groups using foreach operator and use the add sop inside foreach to connect points with similar sortno value.
I hope this helps.

another solution add add SOP->polygons tab->polygon0 0-50(maximum number of points)

another way add add SOP-> polygons tab -> By Group tab -> All Points(in add parameter)

something like this with randomization in connection control and just to avoid connection between two points on the same sphere (If you have large no of points scattered)

And as Kare has pointed out , If you sort you points by z and then just use add sop > polygon > Add - Group of N points say 2 you can get similar output.
