So I've just started looking into DriveWorksExpress.

Very nifty except one major issue for me.

I cant run it unless I specify a rule for the filenames. It comes up that I have missing rules. The problem is I DONT WANT a rule for file names?

It's important for me that the filename doesn't change as I have equations for parts that depend on the state of another part. If the filename changes then it's referencing the old part and gives the wrong value.

I intend on doing a pack and go then using driveworks to drive the new model.

Any help will be hugely appreciated.
