Like lots of companies, our legacy SW part files didn't have freeze bar functionality. Newer files did but we didn't think forward enough to use it. Our problem is with large assemblies, our rebuild times are outrageous. It would be fantastic if we had the ability to run a program on all vaulted part files that opens each file, enables the freeze bar, rolls the freeze bar to the bottom of the feature tree, then saves the file back into the vault.
Pipe dream I know but it would be cool and really increase performance when creating assemblies of 500+ parts.
