Setback fillet corners
Anyone have a easy way or workaround for making setback corners on fillets?

No, i don't think so.

I was inspired by your posts and I've created a FeatureScript to make setback fillet more easily.
It's not really working at the moment but it's a start.

It takes ages but it works !
That is a really cool FS
It should probably be using GeometricContinuity.G1 instead of GeometricContinuity.G2
GeometricContinuity.G1 is tangent, which is what mahir used

Currently it only supports faces with 90-degree edges :-(

You might also want to restrict selecting of planar faces and fillets that are not at corners.
You could update your filter to be:
The end result is mostly the same, but the updated method is more flexible and can be applied to non-cubic corners because it doesn't require a circular pattern. I'm actually almost done with a featurescript version.

Instead of
it's easier to just specify
But if you had two fillets of radius 2mm and one fillet of radius 1mm coming together at a corner, you wouldn't be able to do it.
You also wouldn't be able to do it with conic or curvature fillets
I'm just ignoring that case for now. If you look, joining fillets of different radii isn't pretty at the moment (see below). And dealing with a setback fillet that involves selecting more than just one corner surface seems a bit above and beyond for what is normally just a simple single-radius feature.

It still pretty slow, but I think it will be as long as we use the fill feature
