I have a large number of legacy DWG files in a vault (2013 Pro). I can't seem to extract the data from title blocks automatically but it works if I manually check-out and check-in one of the files in question. Re-index properties doesn't pull the info into Vault. I had the bi-directional mapping set but when I sync properties all it does is sync the empty value from vault over to the dwg and removes the data! I have reverted to mapping from object>vault which happily works on a manual checkout-in but I'm not going to do this for the 10's of 000's of files I have. If I sync properties it simply says 'no changes necessary'. What do?
