Pro/GRINDER

I'm looking for the Creo equivalent of a grinder.

I have a model I need to modify to match scan data.  I need to remove the extra material in the corners of this model but not affect the nearby threads:

I've tried the warp feature but didn't have fine enough control.  I don't own a license or Freestyle or Style.  Would one of these products lay a tight mesh over the entire model and then allow me to pull on any of the nodes in any direction?  Is there a better way?

Thanks.
