We would love to automate our from-to reports. Currently we do them manually. The closest thing I have seen to automation is ITI's CADIQ. Its not designed for From-To and it only works with MBD but it generates a report of differences in models. Honestly for me this would be one of the biggest selling points for moving to MBD. We spend a lot of time generating from-tos.
If anyone else has a better way of doing it I would love to hear about it.
