Sometimes I get vendor imports with the default coordinate system way out in left field. If I choose refit, Creo defaults to refitting to the model including all of the datums. The resulting view sometimes makes the geometry so small that you can't see it. Then its hard to try and zoom up to it to work on it. When you perform a preview when opening the file however Creo zooms to the geometry.
It would be nice if there was a refit to geometry like the preview window does. The code has to already be in place, its just a matter of exposing it so the user can use it.
