Multi body might be very helpful while designing a part, but I still believe it is a methodological mistake to allow them in assemblies. This will cause much trouble in PDMs and other tools that make use of the design structure. Apparently it creates problems even in SW... What do you expect ? 2 balloons for a single entry in BOM ? 1 balloon and some bodies without any ? a single balloon attached to multiple bodies ? looks like SW decided to answer with a question mark ;-) Reminds me of the configurations, another great concept that can be misused as it lacks a clear usage framework (can be used for different sizes, different level of detail, optional features ... or even to defined completely different models in the same document...) Could somebody explain me when it is useful to consider multiple bodies as a single part in an assembly ?
