You question is not sufficient to give a proper answer. Any visualizer can
do what I think you are trying to do.

E.g.

vmd

If you are not a vmd fan try pymol

If you want a very simple user friendly visualizer try discovery studio
(DSV) or Avogadro.

Any of these editors will help you edit your pdb.
