Had an interesting question from a user on the forums recently, where the user needed to create a LOT of tubes on a set of dissimilar but basically parallel curves. Patterning the tubes using one of the OOT pattern features was not an option, due to the specific geometry of the curves. But NX Algorithmic Modeling can come in handy here, enabling the list-based nature of an Algorithmic Feature to handle feeding a long list of curves through the Tube command, one by one. :-) Hope you find this little technique useful!
