Draft Features Failing While Using Family Table

I am using Creo Parametric Release 9.0 and Datecode9.0.3.0

I'm creating a parametric model with family table (end product will be a metal cast part). All basic features (revolves, extrudes, etc) scale appropriately with the values in the family table. However, when I added draft features, these features were failing in the dependent models (not failing in the generic model). It appears that draft features are losing their associativity to the relevant faces/edges/planes/etc, even when these features are still present in the failed model with the same name and number.

Without seeing the failures and the dependencies, this is difficult to diagnose. It sounds like your draft references are not robust in this context. 

In the generic model.

Try to use intent references for the references that are problematic. If intent references are not available, then try creating datum reference features needed to create the drafts..

I concur on this. If the topology (number of curves in a surface, etc.) changes and any edges/surfaces that were used to define the draft are no longer there, the feature will fail. I get hurt by this a lot when bad old models use a bunch of surfaces for offsets, drafts, etc.
