Sweep two rails "Two shapes are too close together"
I am using sweep two rails, and getting the error message "Unable to sweep - two shapes are too close together"
Details: The shape I am trying to create is like the roof of a cave. Arched overhead, with changing arches specified by cross section curves, tapering down to a point at each end.
The rails are mirror images of each other, about 360 mm from end to end. I have cross-section curves defined about every 2 mm. (Generated by mathematics elsewhere.)
I select the two rails, then for cross section curves I select the points at each end and the cross section curves. I get "Unable to sweep - two shapes are too close together".
What are the conditions that produce this error message?
I could stretch the whole thing out by a factor of 10,. So that the cross section curves are 20 mm apart. But I'd like to know if this might help, before I try it.
Thank you.

False alarm: I had to look very closely, but it turned out that some of the cross-section curves were duplicates! So it is not surprising that this produced an error message.
Thanks Pascal for beginning to look at this. And my apolgoes for the false alarm.
