Dear Kukuzry,
Does the family editor allow you to change the names?
Best regards,
Aha. If it is possible manually, there may be a programmatic way also. You probably have to open the family to edit using the EditFamily method, navigate to the type and family parameter to modify and use the FamilyManager.RenameParameter method on it.
For complete completeness sake: yes and no...
