Rebuilding Excel 2013 Data model help

[masplin]

I have yet another untraceable corruption in one of my models so now going through the long winded process of completely rebuilding in a new workbook. The model works fine until I try to update the sql data when it crashed with error messages no one has bene able ot help me with. Same problem on a different machine and if I reinstaleld office. I have about 50 measures defined so wondered if there was any way to copy these out of the old workbook into the new workbook or its going to a long winded cut and paste like i'm doing with all the calculated columns? Just trying to save any more pain than neccessary.

Thanks for any advice

Mike
