For high level and efficient computer aided design it is necessary to provide the possibility of object oriented modeling. A language has been developed to describe features in an object oriented manner including their technological semantics. The resulting generic feature templates are interpreted by the modeling system during runtime. Therefore the specific feature takes the actual design into account. By computing derivable parameters automatically, integrating related standard tables and by regarding design rules, features behave according to their associated semantics. During product gestaltung with features, the user works in his semantical environment and not only with geometric primitives. The concept for the feature design language as well as some examples demonstrating the advantages of the concept are presented.
