Variable Fillet

How do I create a nice variable fillet between the .250 fillet and the .375 fillet? I tried several things, including Mechanical Desktop, but can not get anything acceptable. Jeff

I used blend curve to get the more planar curve instead of the real curvy one that was there. Then did curve pullback to get the curves to the correct surfaces for splitting. Then I did a curve network (tangency) to make the new surface. Do not know if that is what you were looking for?
