    PARIS, Sept. 24 /PRNewswire/ -- In a move that will strengthen the status
 of Open CASCADE components as a 3D modeling application development standard,
 the Open CASCADE company today announced the availability in Open Source of
 three major modules in the area of data exchange.
     Since data transfer between systems is critical to design productivity,
 these three modules will help users save time and obtain high-quality results
 when importing geometrical data and solid model attributes from many different
 types of applications.
     Extended Data Exchange, broadens the definition of data supported by the
 IGES and STEP exchange standards within Open CASCADE.  Shape Healing and
 Sewing enhance user productivity through the automatic correction and
 completion of imperfect or unsuitable data.
 
     Improvements and new features enhance the performance of the three data
 exchange modules:
 
     Extended Data Exchange -- By providing a powerful operator and a
 comprehensive set of tools to read and write data concerning positioning
 within an assembly, colors, names, layers and validation properties, the XDE
 component ensures the reliable transfer of pertinent information attached to
 the geometry of a solid model.  XDE reads and writes STEP and IGES formats and
 gives the user a common way to access these data, regardless of how they are
 described in exchange files.
 
     Shape Healing -- The Shape Healing component connects smoothly to IGES and
 STEP translators, corrects defects such as gaps or incorrect wire orientations
 in imported data, and rapidly creates a useable shape within Open CASCADE. It
 also allows integrated "flavoring" of an IGES or STEP file in write mode:
 unacceptable entities from one system are dynamically changed into acceptable
 entities that can be output to a second system. Shape Healing is especially
 indicated for applications requiring coherent shapes, such as those used for
 analysis, prototyping and measuring machines.
 
     Sewing -- The Sewing algorithm is crucial for shape processing. Featuring
 improvements in the quality of tolerances and in topological capabilities, the
 Sewing component creates connected topology (shells and wires) from a set of
 separate topological elements (faces and edges).  This allows correcting a
 shape without changing its geometrical representation.
