Hello and thanks to eyeryone who has replied and kindly speant time and effort helping me!!!!
I came here to post more but saw that there are new posts lol I will read them after I post...thanks.

I have 5 models in the new attached scene in a row, from right to left

1A- Without any fillet

1B- Fillet of .02 on inside and outside. Was not able to apply inside and outside fillet at the same time to do any variable fillet testing. One after the other only. Sometimes it does not even apply at all.

1C- Variable fillet of .02 going to .3 ( Inside only)

1D- Variable fillet of .02 to .3 on the outside (Outside only)
1D might be the most usable as things stand.

*** 2A- Has brand new geometry in the detail region and on this I am not able to apply any kind of fillet at all!!! Could someone please tell me why I can't apply even .02 fillet on the blue model? What is defective on it compared to the green model?

Thank you very much :-)
