I tried two different ways (check the project file) and both don't work:
1) I created a circle, stored @P.z in attribute @Z, deleted geo but keep pts, ADD node set to “add by attribute Z”. It's able to connect only certain pairs of points. Like in the following pic:
2) I tried to use a boolean, intersecting a TUBE with a set of lines (every line is a prim). It doesn't work.
So when you use add by attribute, the attribute must be integer, otherwise a float attribute would cause issues, like in my case. But in the documentation that's not mentioned, mmhhhhh: Attribute If group by attribute is specified, this attribute will be used to determine how to connect the polygons within the group. Points with the same attribute value will be connected together. The connection order will respect the point order of the group.
ps. I found a way to use the boolean, so one can fill different shapes with parallel lines. I attach the updated solution. Cheers

it doesn't have to be integer value, but since connects all points with the same value it is tricky for float as the values can easily differ by very tiny amount which you will not even see in the spreadsheet as that rounds the values
so to make it work even with float round your z to like 4 or 5 decimal places
