Industrial automation systems and integration -- Product data representation and exchange -- Part 514: Application interpreted construct: Advanced boundary representation

The application interpreted construct defined in this part specifies the interpretation of the generic resources in order to satisfy the following requirements:

  • For the definition of an advanced boundary representation model. An advanced B-rep model is a representation composed of one or more manifold_solid_breps each of which is defined with elementary geometry or sculptured geometry.
  • For the definition of the unbounded geometry of curves and surfaces used in the definition of the faces of such a B-rep model.
  • For the definition of the topological structure of a B-rep model. In particular all surfaces are bounded by defining an associated advanced_face and all curves are bounded by reference from a topological edge_curve.

This AIC is independent of any industrial application domain.

The following are within the scope of this part of ISO 10303:

  • 3D geometry;
  • B-reps:
  • B-rep models;
  • B-spline curves and surfaces;
  • conies;
  • elementary curves;
  • elementary surfaces;
  • geometric transformations;
  • polylines;
  • pcurves;
  • sculptured surfaces;
  • surface curves;
  • swept surfaces;
  • twisted curves;
  • unbounded geometry;
  • use of topology to bound geometric entities.

The following are outside the scope of this part of ISO 10303:

  • 2D geometry other than for the definition of a pcurve in the parameter space of a surface;
  • bounded curves other than polylines and B-spline curves;
  • bounded surfaces other than B-spline surfaces;
  • offset curves and surfaces.
