ISO 10303-511:2001 (R2024)

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.
