Fillet Edge Fail

Can any one tell me why the these edges fail, when I try and fillet the edge with .1" radius fillet. If I explode the surfaces and just join those the fillet fails on back together it works fine. I don’t know if it related to V6 or not haven’t had time to test it in V5.

Hi - djnelson - there is a tiny edge on the vertical that is away from the camera that is easy to miss:

Use MergeAllEdges or chain the edge selection and it should work.

Thanks that worked.
