Hi Mala, there is a command Transform > Deform > Flow
(https://moi3d.com/4.0/docs/moi_command_reference8.htm#flow)
which can do bending but it works better for bending a straight object onto a curved path and also it can be difficult for it to bend just one small area of an object instead of the whole thing.

The kind of localized bend that you want is probably better done in a polygon modeling program.
