ISO 10303-507:2001

Industrial automation systems and integration — Product data representation and exchange — Part 507: Application interpreted construct: Geometrically bounded surface

This part of ISO 10303 specifies the interpretation of the integrated resources in order to satisfy requirements

for the representation of geometric shapes by means of geometrically bounded surface models.

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

— 3D points;

— points defined in the parameter space of curves or surfaces;

— 3D curves;

— curves defined in the parameter space of surfaces;

NOTE - Such curves are also known as pcurves or cons, which are acronyms for parametrised curve

and curve on surface.

— the elementary curves line, circle, ellipse, parabola, and hyperbola;

— intersection curves;

— polylines that consist of at least three points;

— surfaces;

— the elementary surfaces plane, cylinder, cone, torus, and sphere;

— swept surfaces created by rotation or linear extrusion of a curve;

— sculptured curves and surfaces;

— trimming of curves and surfaces;

— composition of curves and surfaces;

— replication of curves, surfaces, and surface models;

— 3D offsets of curves and surfaces.

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

— unbounded geometry;

— self-intersecting geometry;

— geometry in a 2D cartesian coordinate space;

— replication of points;

— topological entities.
