In assembly, part, and sheet metal, the following enhancements were made to the Unite Bodies command:

• You no longer have to create a mid-surface or copy construction geometry before you can use the Unite Bodies command. Instead, you can select the design body and the Unite Bodies command fetches the geometry for you.

• You can select geometry that consists of manifold (non-shared) topology, such as weldment assemblies, without having to define assembly connectors.

  Previously, you could only select geometry with shared edges.

  

• When creating a study for a model that contains united bodies, use the following mesh types:

  • Mixed and General Bodies (assemblies)

  • General Bodies (part and sheet metal)
