Defeature fillets using script

Hi all,

I am writing a script to detect fillets in a geometry and defeature it.

Right now i am using *separate_fillets command for fillet separation based on the given radius ranges (0-2, 2-4, 4-8, ....).

But it is not giving a proper output. Some surfaces are missing in between and when i try to defeature, surfaces are getting destroyed.

Is there any other command to detect/defeature fillets properly based on the given radius?
