Which of the following does not help determine whether a part contains interpart expressions?

Determining whether a part contains interpart expressions involves examining how parts interact within a broader assembly context. The Assembly Navigator specifically focuses on the structure of the assembly itself, such as components and relationships, rather than delving into the details of individual parts and their expressions.

The tools mentioned in the other choices, such as Tools->Expressions, allow you to directly view and manage expressions related to a part. The Part Navigator directly reflects the part’s features and expressions. Running a Check-Mate test provides a quality assurance function, which includes checking for interpart dependencies among various components.

Since the Assembly Navigator does not provide the necessary insights into the expressions within a part, it is not a suitable tool for determining the presence of interpart expressions.
