Thanks Martin. Weighting edges for beveling worked but now I have a doubt because I did not expected that result in my original model. Why did the model loose the bevel when extruding that interior faces?. I have posted a picture to clarify the question.

As soon as I press E to extrude:

I guess it has something to do with the new edges created but don’t understand why it interferes in the outside bevel. The edge loops building this face doesn’t even touch any part of the bevel.
Cheers!
