Hi Finema,

You'll have to try a variety of different radius values, some radius values will work and others will be problematic. If you examine the very ends of the fillet when putting on the large one, you'll see some radius values leave a little wiggle in the shape at the very end, if that happens then the smaller fillets won't work although they may work on one side.

Like I mentioned above, these are some pretty difficult cases for filleting and you may need to use a different CAD program to put them in.
