Not sure if its the same, but have a look at this discussion from a couple of weeks ago when I had a problem with intersections

I'm speaking under correction here, but in some instances Cross Reference has the same affect as Grafting a list(or two). So because you Flattened all the lists involved you created kind of "clean" slate to then Cross Reference all the items in the two flattened lists.

I am really not sure if this applies to your situation here, but its not as simple as then Grafting all the lists, because sometimes only one of the two lists being used for input needs to be grafted. Main thing I guess to keep in mind is that Path management and Lists settings (Cross Reference) can have similar affects or even interfere with eachother.

Is the "sweep" a single item?

Thanks guys for your help,
here is on the image the "sweep" i was getting which is creating several surfaces.
Since i needed a continuous surface i had to go through a lot of steps as you can see on the image.
I had to fill these gaps and then get a new continuous surface.
The purpose of all this is to get a gutter that can vary in its width.

Ok, I will try to sum this up simply. I will use the Brep/Plane Intersection as an example.

Either your Breps or Planes need to be Grafted and the other Flattened.

Or both flattened and intersect component set to Cross Section.

Its the same affect. But both cannot be Grafted and set to Cross section, that won't work.
