Radiate command(V7 SR11)doesn't work well

-The Radiate command doesn’t work like in the help Video.
-The find Radiate command doesn’t work as it should : after picking the 2nd subD surf when
moving the 1st subD surf all the row move.
Thank You

I watched your videos and everything behaves as it should. I think there is a misunderstanding on your side. In the first video if you want to create tangles you need to extrude the face not just move it. (move and then hold ctrl).

Matthias, You are right
Thank You
