Hi Misiu, yes like Pilou writes above you can use the Transform > Deform > Flow command to deform objects from a straight line onto a bent curve, or also from a flat base plane onto a curved surface.

Please take a look at the help file topic for Flow for an extended description of it:

Also some links to previous forum discussions about Flow here:
