Meaning: This occurs only during a paste operation where a member part has an assembly connection at an end but another assembly connection is being pasted at the same member end. Two assembly connections cannot apply separate trim operations; hence, one assembly connection must be removed. The paste operation cannot remove the assembly connection so the paste assembly connection is set to "inoperative" and tagged with a To Do List record.
Recovery: Select the assembly connection in the To Do List. Click Delete .
