Add a "Negative" radius for clearance

[karthur1]

When providing for clearance in corners, we are sometimes required to provide for a "negative" corner radius.  Presently, Inventor does not allow for this and we have to use other means to place this feature (new sketch and extrude, ifeatures...etc).  I would like to be able to either enter a negative value for the fillet, or have an option in the fillet command to run the fillet the opposite direction.  In the image below, I show the "negative" fillet.

Thanks,

Kirk

That's a awesome idea karthur1 I can see how this would save time.

Great Idea, even though I think its a duplicate request, I would love to see this feature.

A verry good sugestion.

I dont care about the semantics; Put it in the filet tool and give us a button were we can select negativ or positif.

Guys, if this would also work on a turned part (say, undercut corner in the shoulder between larger and smaller diameter), that would be fantastic.

Of course that doesn't simplify making a square groove undercut, but a radius undercut is effective enough and it totally belongs in the fillet tool.

Dear Autodesk Inventor,

We have Command for Fillet and Corner round the Circle with center in

I need, we need, pls  build the Command for Fillet and Corner round the Circle out with center at corner (image below)

This idea has been implemented within Autodesk Inventor 2019. Special thanks to everyone who cast a vote for it.  A new "Inverted Fillet" option can be set via the Type drop down when creating or editing a Fillet.
