When installing NM cable in attic area

[Paampguy]

Isn't there something in the code book somewhere about when installing nm cable in an attic area it is okay to run the cables across the top of the floor joist as long as the distance between the floor joist and the roof truss is not more than 3 feet in height, thanks
