Attached is an existing part that I have worked with in the past.  I'm trying to create some similar solid models but having no luck.  If you look at the part it has blunt corners on the nose of the part.  I can't figure out how to model a part with blunt corners similar to the part I attached as an example.  It's not a fillet and I can't seem to get any kind of surface to match that shape.  Any help would be greatly appreciated.
