Hi Michael,

While playing with the Danny's model from the Smooth transition thread
http://moi3d.com/forum/index.php?webtag=MOI

I've find a strange g2 fillet behavior.



Here's the 3 tubes construction I did, then I try to fillet it :

- Circular works, only if I fillet intersection edges one by one (at a size of 6 I was able to fillet the 3 edges in once)
- G1 or G2 lost continuity in the fillet

However I was able to use the g2 blend surface after deleting the 3 'wrong' fillets.

I don't know if it's possible to enhance the fillet in this particular area. There are many works around of course.
