What happens if a part has a link to another part that is not loaded when the assembly is opened?

When an assembly contains a link to another part that is not loaded, the typical behavior in Siemens NX is for the assembly to open but with warnings regarding the unresolved links. This means that the assembly model can still be accessed and viewed, but the software alerts the user that there are components missing. This warning serves as a reminder that certain features, constraints, or references tied to the unloaded part may not function correctly until that part is available.

This behavior allows users to work on their assemblies without being completely blocked by missing components, enabling a more flexible workflow. In contrast, if the assembly were to refuse to open or completely ignore the missing part, it would hinder the user’s ability to utilize the assembly context. Therefore, the correct response indicates that the system alerts users about the missing link while still allowing access to the assembly structure.
