Remove the alignment between design occurrences and part occurrences
Procedure

To deselect an occurrence, click CTRL and select the occurrence again.
Click Remove Alignment.
If you see any error while alignment is getting removed, contact your administrator.
The indicator shows that the design occurrence and part occurrence are no longer aligned with each other.
A design occurrence may be aligned to more than one part occurrence. Similarly, a part occurrence may be aligned to more than one design occurrence.
To remove all the part occurrences aligned to a design occurrence, select the design occurrence from the design structure and click Remove Alignment.
To remove all the design occurrences aligned to a part occurrence, select the part occurrence and click Remove Alignment.
For a bought out part, you must also remove the alignment between the part and design. On not doing so, you can still visualize the bought out part on its floor position.
