beat out rounded mesh

Hi
I want to convert a rounded/smoothed mesh partially
from:
.
x.
xx.
xxxx.
xxxxxxx.
to:
.
.
x.
xx.
xxxxxxx.
on both sides. (only look at the points, the x are only for displaying in the forum) Left and right if looking from the front.
Many thanks.

I’m not really clear on what you mean. I think maybe you want the bevel tool. could you clarify a bit?

you have to turn on this
