Is there a way to deselect edges from a face selection in chamfer/fillet?

[CL9YAJC]

I'm wanting to face select both sides of this part to chamfer everything inside it, and deselect all the countersunk holes so it doesn't try to chamfer them again. Is there a way to do this or do I have to select each individual edge...

If you countersink holes are placed last, in your timeline, you can simply move the timeline marker before the holes, do the chamfer using faces, then drag the timeline back to the end of the timeline to return the holes.  If you holes are not at the end of the timeline, you may be able to move them there first.

If this is not feasible, you are probably destine to do it using the long method.

If you select a face, that is defined to select ALL edges of that face.  You can, however, window-select edges (set your filter to just edges), then de-select the edges you don't want by holding down CTRL (CMD) on Mac.

I'm trying to apply a fillet to only the outside edges of a face on an object.   After selecting the fillet command, when I select the face of interest, the fillet is applied as I want it to the outside edges of the object but it also fillets edges associated with holes that I've cut into the interior side of that face.  When hold down the CMD key on my Mac to deselect the interior edges that I don't want to fillet, it seems to deselect all edges (since the fillets go away when holding down the key).  When I click on an edge with the CMD key held down, it asks for a new fillet radius rather than deselecting it.   Am I using the CMD key incorrectly?  I created a much simpler object - a cube with a hole going through it.  When I select the fillet command and select one of the faces with the hole in it, it applies the fillet to the edge of the cube and the edges of the hole as well.  I only want to fillet the edges of the cube, not the hole.  On the simpler object, I am able to individually select the outside edges of the face with the hole in it and apply the fillet to those edges only which accomplishes my objective of only applying the fillet to just the outside edges and not the hole.  Unfortunately, I can't do this with the object of interest.  When I try to apply the fillet by selecting the individual edges on the outside edge of the face, I get an error that says "The filet/chamfer could not be created at the requested size.  This might be occurring at the ends of the selected edges.  Try adjusting the size or using multiple separate operations.    Check that the selected edge chain ends at a sensible position, and if not try selecting more edges".  When I apply the fillet to the face, it applies fine at the size I want it except that it also fillets edges of the interior holes on that face..

First:  CMD does not de-select anything.  Holding down CMD (CTRL) does, however, roll back the actual fillet.  When you let up on CMD, the fillet preview will be re-applied.  This is done because fillet consumes the selected items (edges), so you need a way to de-select an edge if you mistakenly selected it.  This allows you to, say, select 3 edges, start fillet, apply a radius (fillet preview is shown, and edges are consumed).  Then, hold down CMD, the fillet preview is rolled back, click on one of the 3 edges.  It will be de-selected.  Let up CMD, and the fillet preview re-appears (now on 2 edges).

But, to your basic question:  There is no way today, that I know of, to specify "I only want to fillet all the outer boundary edges of a face, not the inner holes in the face".  Face selection is specified to just fillet all edges of that face.  The only way to do this that I am aware of is to manually select the outer boundary edges of the face.  Unless they happen to be tangent continuous.  Then, chain selection will select a chain of edges with a single selection.

Thanks for the response.  When you say CMD (CTRL), I assume you mean CMD on Mac and CTRL on Windows, not to press both keys.  Is that correct?

I'll take a look at the boundary edges of the face to see if I can determine why specific rounded corners on the face are giving the error message when I try to select them to apply a fillet

"When you say CMD (CTRL), I assume you mean CMD on Mac and CTRL on Windows, not to press both keys.  Is that correct?"

That is correct.  Thanks for pointing that out.  Reading it back, I can see where that might be confusing.
