You can modify body cross sections in a drawing and set the hatching properties for each body.

User Interface Location: In the Menu Manager for MOD XHATCH, select X-Body.

Release: Creo Parametric 7.0.0.0

See the video on the Learning Connector.

With a multibody part you can define different section properties for each body such as assigning a different material for each body. In the MOD XHATCH menu, select the body for which you want to modify section properties. You can select the desired body from the body node in the Model Tree or by navigating across the bodies in the model using Next and Previous in the MOD XHATCH menu. This gives you more control over the hatching properties for parts designed using multibody.

In the picture below, the black arrow points to a housing body and the green arrow points to an over-mold body.
