Full Description
This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy requirements for the description of geometric shapes by means of non-manifold 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;the elementary curve types line, circle, ellipse, parabola, and hyperbola;intersection curves;polylines that consist of at least three points;the elementary surface types 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 using topological entities;composition of curves and surfaces using topological entities;replication of curves, surfaces, and surface models;3D offsets of curves and surfaces;non-manifolds.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;topology without an association to a corresponding geometric domain.
