To integrate CA*-systems with other applications in the world of CIM, one principal approach currently under development is based on feature representation. It enables any CIM component to recognize the higher-level entities--the so-called features--out of a lower-data exchange format, which might be the internal representation of a CAD system as well as some standard data exchange format. In this paper we present a 'made-to-measure' editor for representing features in the higher-level domain specific representation language FEAT-REP -- a representation language based on a (feature-) specific attributed node labeled graph grammar. This intelligent tool, shortly called GGD, supports the knowledge engineer during the representation process by structuring the knowledge base using a conceptual language and by verifying several characteristics of the features.
