Hi !
I can’t manage to bend a portion of an object
seems like bend arc bends only whole object and gizmo isn’t adjustable
and bend curve is different tool it is also for whole object
Uploaded picture that demonstrates what I’m trying to achieve
red line is the only portion I want to bend , green arc is what I want to have
thanks !
well the way I see it is would be with transpose line, but since You want to bend it in just one place where you have denser mesh it would be some clicking.
other way it would be imm curve.
and other it would be zmodeler, extruding one level by one and bending it significantly.
probably there are some other ways 
Why Bend curve doesn’t work?
try to crank up curve resolution and only bend just that part you want.
