I have a model where several dimensions have been renamed via their properties, i.e. d4 was renamed "length" etc. How do I find the original name for length was d4? IFX wants the original names, but I cannot find this in the information or properties anywhere, yet if I add a relation d4=1.00 the length will change to 1.00. When I reopen the relations editor that line now says length=1.00. Not a practical way to track these down.
