spin and scsling

is there a way to spin and scale at the sime time following th side of a sector in 3D

see pic

the normal spin spin functin of the radius but does not affect the scale of the pinned object

but i wold like to have a scaling done at the same time to follow the sector width functin of the angle of altitude

anybody ahs an idea on how to do this like apie cut in3D

i need this to presere the faces otherwise i wold need to redo all the faces manually
and also keep the curving of all the faces!
