Hi Michael,

From time to time I encounter a trouble while filleting a corners of curve. I'm sorry I didn't reported it before.
I don't know whether it can be caused by some specific angle which forms a corner. It seems not to be noticeable at least.
In case of failure of fillet I must separate curve and then filleting corner-by-corner -- it works -- or draw a tangent circle and trim all stuff by hand.
Any thoughts on it?

Filleting right shape fails... (3dm file)
