ISO/TS 10303-1509:2008 specifies the application module for Manifold surface.

The following are within the scope of ISO/TS 10303-1509:2008:

• 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;
• 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 using topological entities;
• composition of curves and surfaces using topological entities;
• replication of curves, surfaces and of surface models;
• 3D offsets of curves and surfaces;
• items within the scope of application module Topologically bounded surface, ISO/TS 10303-1511.
