1. A method for generating a feature in a computer-implemented solid modeling system, comprising:

  • (a) setting one or more attribute values to indicate whether extended start and end segments for each chain of an open profile intersect with a part modeled in the system;

    (b) inserting the open profile and sheet with attributes into a tool;

    (c) uniting the tool with the inserted open profile and sheet with the part to create a cellular topology graph structure, wherein the attributes get propagated to the cellular topology graph structure; and

    (d) generating the feature from one or more cells selected from the cellular topology graph structure based on the propagated attributes.
