This document specifies the integrated resource constructs for Mechanical features. The following are within the scope of this document: constraints on life cycle context invariant identifiers for topological items; counterbore, countersink, counterdrill, and spotface description and application; features that are to be manufactured by either milling or turning processes; features that can be replicated in patterns; generic mechanical design concepts; implicit representation of machining features through selection of standard parameters; machining feature definition elements necessary for creating machining features; machining features for defining shapes necessary for manufacturing; product and manufacturing information placeholder in a three dimensional geometric model; shape representations necessary for creating machining features.
