STL file

i need to edit a STL file and i can only import it but not edit it

Onshape does not support editing mesh files.  Generally you would want to use a Mesh editor rather than a CAD program.  Can you get the file in a CAD format (parasolid, STEP, IGES etc)?

If not this thread has advice on good mesh editors:

You could try Freecad, which so far as I've played with it, appears to be able to import STLs, manipulate meshes, and convert to a solid, and export as STEP..... which Onshape can then use...

I tried "STL to STEP"  with FreeCAD (www.freecadweb.org). It works very well (with a small part).

See instructions (e.g.) :
