Covers -For anyone who’s unfamiliar with multibody modeling, it allows you to create a part with several independent bodies. Because you’re not merging these solid bodies with the rest of the part, you have a lot more flexibility when it comes to managing, visualizing, and designing separate geometric volumes. This gives you a great deal of control in the areas of generative design, additive manufacturing, simulation, and also in your daily design workflows. For example, you could …
- Apply appearances to bodies
- Show or hide selected bodies
- Include or exclude bodies from calculations
Creo Parametric 7.0 supports creation and use of bodies that can act as modification tools used to change geometry in other design bodies.
