What editing operations do you have in mind? There's not a lot of
structure permitted in STL, unfortunately; e.g. it doesn't support any
features for tagging part of the surface as something like a `Physical
Surface' in Gmsh. Some codes get around this limitation by using
several STL surfaces to represent domain boundaries; e.g. one for the
inlet/source patch, another for outlet/sink patch, and a third for the
rest of the boundary.
You can do some simple transformations with ADMesh like dilation,
translation, eversion, etc. (careful though, their website is really
broken at the moment
MeshLab <http://meshlab.sf.net> looks good, but I haven't tried it yet
myself. I haven't tried Salome either.
