This is a post by Dave Martin on the PTC site.
Since the introduction of multibody modeling in Creo Parametric 7.0, I’ve seen and heard a lot of comments and responses along the lines of:
- Multibody modeling isn’t needed because you have skeletons and data-sharing features in top-down design.
- Now that you have multibody modeling, you no longer need to use skeletons, data-sharing features, or top-down design.
Some responses have been even more visceral: Multibody is a betrayal for Creo’s most experienced users. The other side says users shouldn’t have been forced to use top-down design for so long, when Creo could have implemented multibody.
