If a reference set is deleted from a component part that is used in multiple assemblies, what reference set will be used in its place the next time one of the assemblies is opened?

When a reference set is deleted from a component part that is utilized in multiple assemblies, the behavior of the software is predefined to facilitate continued functionality. The next available reference set defined in the Assembly Load Options will be used in place of the deleted reference set the next time one of the assemblies is opened.

This means that Siemens NX has a systematic approach to handling reference sets to ensure that assemblies remain intact and functional, minimizing disruptions caused by the absence of a specific reference set. The Assembly Load Options allow users to manage these reference sets effectively, designating a sequence or priority for what should be loaded if the preferred set is unavailable. Thus, it ensures that a valid reference set continues to support the assembly's functionality without manual intervention.

In contrast, other options like using the empty reference set would not provide the necessary context or geometry, leading to potential errors in assembly representation. The model reference set could be a straightforward option, but it is not necessarily the next in line according to the assembly load options. Lastly, a user-defined reference set may not be predefined in the context of the deletions and would not necessarily be perceived as "next available." Therefore, relying on the Assembly Load Options is a more robust solution in this scenario.
