problem creating new pipes

[kriffo]

Bye to all,
I am new in the forum and I would have to ask a question, I created a new family of pipes in which I modified the dn, outer diameter and inside of the tube, up to here everything ok but the problem is that when I go to make a curve the latter does not take the characteristics of the new pipe created previously.

I also attach a clearer picture of the problem. Thank you all!

Did you change the nominal radius even in the elbow?

Hi thanks for the answer, no I didn't change it, how should I do it? I'm still at first with revit...
