Solid model, unable to delete face (hole)

[scottS4EDN]

I have a step file of an iPhone.  I'm learning how to make changes to solid models.  I'm stuck making an edit I can't get F360 to do.  I'm deleting some features from the original solid model.  In particular some holes in the bottom of this phone.  I was able to delete the other holes by using the move tool and moving them into space (Delete would not work for me, gave an error).  I'm left with a couple of holes that would not delete using any method I've tried.  The difference I see is that they intersect some faces near the corner of the phone, whereas the ones that worked were not in the corner faces at all.  Can someone explain how I can delete these holes without hosing the existing geometry?

See screenshot, and f360 source file

Hi @scottS4EDN,

Have you tried using the patch tool under surfaces, Make patches of either side, join using a loft, and then boundary fill to create a body. You can then combine to turn into a single body.

The "healing" functionality in Fusion 360 clearly has a problem with these holes.

What Fusion 360 would really need is a properly working un-trim function, something a number of us have asked for for a long time. 

I've tried the patch function but on these surfaces, the results were less than satisfying. I can do this in Fusion with splitting and mirroring surfaces, but in the end, it was quicker to do this in ZW3D using the un-trim function there.

The result is a solid body without any of the holes.
