Hi again,
actually, when reading your post I realized it can be even simpler. Since I am on Linux I do not need ModelCenter at all, in fact it is easier without.
A nifty combo of grep and sed will swiftly replace "GenericModels.Generator" with "ElectricalModels.Generator" in all files (i.e. models).
(One can do the same in windows since the bash shell is now available).
I'll try this tomorrow. And backup before beginning...
Regards
