If you’re looking for an easier way to clean up unused assembly constraints, this article is for you. The more constraints an assembly has, the longer it can take to load or update in NX. For this reason, it’s important to regularly cleanup constraints that are no longer being used in the assembly. Often though—particularly in the case of large or complex assemblies—it can be difficult to sort through all of them. How do you quickly identify which constraints are being used or not?
Once again, the experts in the NX Design Forum have come through with an answer for us. (You can check out the original question and answers in the forum.) The Constraint Navigator in NX has many options to filter constraints, so you can understand what’s happening in your assembly. The status column indicates where any issues are.
Use the Constraint Navigator to filter and trace the assembly constraints that are not associated with any component in the assembly.
While removing/deleting the component from the assembly, NX will prompt you whether to delete the constraints associated with the component. When the 'Group by Constraints' filter is set, the constraints which are not associated with any component will not show the '+' node sign. You will have to delete them manually.
