Lost feature ??

I am getting old i guess.

I have used a feture from SU to make a face between two lines.
You select the two lines and SU makes the face between the two lines. But I can't find it any more.
Does anyone know which tools I need / how it is called ?

Thank you very mch in advance.

Curviloft by Fredo 6 can make that! And maybe more!

Thank you !
Not what I used before but looks like a quantum leap forward.
