For your cases 3 and 5, you're looking at real loads on the restraints (because these are basic load cases). For cases 7 and 9 you're looking at restraint differences between two states (these are combination load cases).

For case 11, you have the sum of two differences (a combination of combination cases). Now you want to add this to a basic load case ...

I suggest you send your job to techsupport@coade.com and explain your rational for setting up these load cases.
