Mis Classified Graph Preventing Radius Along Spline Edge

[moonco26]

I am trying to put a radius along the highlighted edge. The shape is defined by a fixed spline before being extruded. What can I be done to fix this?

offsetting fit point splines, and projecting curve edges into sketches are both problematic b/c they tend to degrade the curve quality, often to the point that things like fillet can't be  done on bodies made from these sketches.

I initially assumed this was the source of the issue since you did this in your sketches. 

turns out the problem was that mirror.  your mirroring the rib back on to itself, and you don't appear to actually be changing any geometry with it.  this seems to be confusing fusion.  when you suppress it (after removing it from the pattern), you can get at least a bit of a fillet on that edge-

if you need the fillet any bigger, you'll have to fix the sketch that creates this sliver of a face, as it's is preventing the fillet from getting any larger-

Thank you for your help! This project has been a challenge due to these splines. These parts fit over an existing part and need to match as closely as possible while retaining the ability to be injection molded.
