Multiply on a rail

hello!!! impossible to multiply yje group (yellow) in 12 items matched at the surface of the tube… neither free form, nor parralel at the D plan… I miss something, of course, but what??? thank you for help!!!

Hello - please post a file with the objects, I’ll take a look.


hello!!! I have understood: the item (yellow highlighted) I want to array has to be at the beginning of the curve, which in this case is an isocurve on the tube… As soon I moved the item at thje beginning, the array become perfect… thank you !!!
