Did you ever had to change OmniClass number in your families?
This is very easy task if you just have one family to edit. But if you have a case to modify several families this task could be very time consuming. To speed up the editing you can use a Category Update tool in Content Admin Kit tab. Tool offers you to automatically update OmniClass Number and Title with it, by defining new number and apply it to whole folder of Revit families on your computer.
