CADSharp & RENDERCAD have sponsored a new custom feature:

.

Deform
It deforms a parts and surfaces via profile sections or lattice grids along a path. Useful when you need to bend, twist, and scale parts after they have already been modeled.

Note: It is still a work in progress but I think its good enough for first release.
