Hi Rudy,

I've taken a slightly different approach to this problem.
Here's my version for you.

Being that you already know that you want a 0.5mm Fillet to the inside edge of your ring...
...I usually add it straight to the Sweep Profiles that I intend using!

Hope this helps, Colin

Thank you guys,
I appreciate all your effort.
Yes, Colin...I do that sometimes,....
Thank you very much to all!!

Rudy
