Would like to see drawing compare added back into Vault. This was part of Design Review several years ago and it allowed you to overlay two .idw's and it would identify the differences. This was removed in about the 2008/2009 release of Vault/Design Review. It was similar to the BOM compare. And...it did work. We often need to compare the .idw's attached to an item from one revision to another. We lost alot when this feature left.
