Hi Karsten
I replaced costruction 2 with your last
it seems to run better .....
File opening the output of the second Fillet
it does not work... ( picture-1)
I redid the connections, and it works , but creates
the surface Brep source ( why ?)( picture-2)
Saved, and reopened it's ok....... (picture-3)
I think which you , maybe I should spend a little more time
for the exact functioning of Node Fillet,
which it is really very important-
I saw the new Offset node
I hope functions ,
then we resend-
Good work..Great Karsten
best
