I am trying to combine multiple drawings from an assembly into a multi-sheet drawing. I've been able to do it successfully with 4 sheets using click+drag and/or copy+paste into the main assembly drawing (creating new sheets...)

My problem is any drawing I'm trying to add now has all of the dimensions break (showing up in yellow). Does anyone know of common pitfalls or issues I may run in to combining drawings like this? Really don't want to re-do the dimensions on the next 12 drawings, especially when I had my hopes up since the first few pages went so smoothly!

Thanks all.
