---------------
Component patterns have replaced component arrays.
Previous versions of NX allowed editing and deleting a component array from
Assemblies --> Edit Component Array --> Delete Array.
Attempting to delete a pre-NX10 master component array in NX12, you would get this message:
How do you delete the master component array in NX12?
Solution
From the assembly navigator, you can delete the master array from the
Component Patterns node by selecting it and RMB --> Delete.
