ISO/TS 10303-1507:2018-11 specifies the application module for
Geometrically bounded surface.

The following are within the scope of
ISO/TS 10303-1507:2018-11:

• 3D points;
• points defined in the parameter space of curves or surfaces;
• 3D curves;
• curves defined in the parameter space of surfaces;
• 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.
