Industrial automation systems and integration — Product data representation and exchange — Part 511: Application interpreted construct: Topologically bounded surface

This part of ISO 10303 specifies the interpretation of the itegrated resources to satisfy the requirement

for the definition of a face with explicit topological bounds and fully defined geometry.

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

— 3D geometry;

— B-spline curves and surfaces;

— conics;

— elementary curves;

— elementary surfaces;

— polylines;

— pcurves;

— sculptured surfaces;

— surface curves referencing pcurves;

— swept surfaces;

— twisted curves;

— unbounded geometry;

— geometric transformations;

— 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.
