Var Fillet on non-tangent curve edges

Once again, I run head on into a fillet problem. When trying to apply a variable fillet on a extruded curve composed of several nearly tangent (but not exactly) arcs, I consistently get errors. I can apply the variable fillet on one section, but not two or more together. I did a quick experiement where I drew a closed sketch made up of 4 arcs connected but no tangent. Extruded then tried var. fillet to no avail (error try smaller radius - which does not work). When I went back in a made all but two tangent, the variable fillet works. Has anyone else have an issue with this? Is it that hard for a MCAD program of this level to do this?
It has gotten to the point where my boss has asked to consider farming this project out 'cuz I can't get IV to do a simple fillet! If it is because of my ignorance, I can take it, but I have tried everything that my 3.5 years of IV experience could muster......

I've had many issues with fillets. Maybe your in
the same situation as me, reverse engineering castings? Could you post it in CF.
If not me, maybe someone else can figure it out.

I did post the "dummy" or quickie example in CF.

I have the extreme fun task of re-creating 3D parts (and subsequent tooling) from hand-drawn vellum files. I would ideally do the shape via lofting, but alas IV is handicapped when it comes to radial lofts with variable cross sections (no 3D guide rails options).

I don't know why it can't do it. Maybe an Adesk
brain can explain why. I was told by my VAR that there are hundred of thousands
of fillet variations and Inv cannot provide for all. $$$$. Sometimes you got to
tweak your design.

Well perhaps I am underestimating the difficulty of a fillet......
