Copy geometry, merge, and publish geometry can be used to maintain associativity.Multibody modeling simplifies part and assembly design. No extra assembly constraints are required.

Subsequently, one can extract each body as separate components and create an assembly with the associated linkage between body and part. In case of assembly design, multibody functionality can be used effectively to create an assembly in a part environment. Another good point about multibody is assigning different materials and defining their corresponding parameters which later can be consumed in drawings. Designers can create two separate bodies for interior & exterior geometry, easily remove one body from another with a Boolean operation & save time.

Now with new multibody functionality, it would be a much easier task. Designers used to spend maximum time to get this done. It was a very time consuming activity to create geometry with the surface, merge it as one surface, and then remove it from outer geometry. While converting those interior surfaces into solid, they removed them from the solid exterior geometry that creates internal casting cavities, as shown in Figure 1.

In the case of complex casting design, for creating interior cavity portion, designers create it in the surfaces and later merge all surfaces into a single surface. Overview of Multibody Modeling:īefore introducing multibody functionality in Creo parametric, if two features or their geometry intersected, these intersected geometry volumes were merging with each other. PTC has introduced multibody modeling one of the essential enhancements in Creo Parametric 7.0 and above.
