< looking curve poking out from them, but that is just a display artifact.
< They actually are

If after the automatic Sweep I make a zoom the "end" (snap point of the path) and middle of the rectangle writed "Center" are different.
Shown by my little green part image above (the x of the "center" was very blury)
Do you mean they are same? If yes that is perfect for me! Very cool! :)
I will made my line array curve from the end of path and not from the center of rectangle for more security


< then why do you care where the middle is?
for start to move from a known position
But with your last comment there is no more problem, i take just an odd array curve and I have the middle ;)
