      Report de recerca
      Accés obert
      CAD systems are usually based on a tensor product representation of free form surfaces. Trimmed patches provide a reasonable solution for the representation of general topologies, provided that the gap between equivalent ...

    • On user-defined features 

      Christoph, Hoffmann M; Joan Arinyo, Robert (1996-10)
      Report de recerca
      Accés obert
      Feature-based design is becoming one of the basic design paradigms of CAD systems. In this paradigm the basic unit is a feature and parts are constructed from a sequence of feature attachment operations. The type and ...
