I think that for mold design you really want to look into something
like TDO (Tool design Option)  This reinforces the master-model
concept and works initially with surfaces.  TDO can streamline the
process quite a but, but needs the .mfg file in session to force
updates (I think)

I use Pro-E for forge tooling design with a master cavity model that
has a co-ord system included for tooling placement.  The outer skin
geometry is surfaces that are 'published'.  The tooling then uses
external-copy-geom to include the published geometry from the cavity
in the die model as surfaces.  The advantage of using published
geometry is that you can add or subtract surface patches without
bombing downstream features that depend on the published geometry as a
whole.

Using surfaces vs. solids avoids the problems associated with matching
accuracies between solids, especially of you go on to create die EDM
electrodes from the die models.

Now, none of this works unless you have the right config,pro options
turned on to propagate changes and update models.

I don't use Interlink/PDMlink, so I can't comment on how that affects
the mix.

I could give you an example if you like,
