ISO 10303-511:2001 PDF

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.
