  ABSTRACT
          The current research provides and approach to the development of a
  computer system architecture for mechanical conceptual design within a
  virtual environment -- COVIRDS  (COnceptual VIRtual Design System). 
  Conceptual design refers to the creation of an initial shape of a part or
  artifact that is being designed.  During conceptual design, product
  specifications are not rigidly defined and the designer has some freedom in
  determining the features of the product.  Currently, however
  Computer-Aided-Design (CAD) systems require the designer to specify
  detailed geometry of the part even though the final part may be
  significantly different from the preliminary concept designed.  COVIRDS
  provides an interactive three dimensional (3D) environment for designing,
  where the designer can use a combination of hand gestures, voice input, and
  keyboard input to create and view a 3D artifact.

  TITLE: Shape Feature Extraction from Non-linear solid models in
  Design-Manufacturing Integration
  
  An approach to feature extraction from non-linear solid models is being
  developed that attempts to resolve the following typical problems in most
  feature extraction approaches : 1) Variation in topology
  among features, 2) Variation in geometry among features, and 3) Exponential
  complexity of most feature recognition algorithms. The approach utilizes a
  unique definition of features in terms of projections and depressions. 
  Once features are recognized, they are represented within a feature
  relationships network, which is used as input by a knowledge-based expert
  system to evaluate
  manufacturability of a part design.  Applications include injection
  molding, die-casting and forging.
