Part 1509:
Application module: Manifold surface

1 Scope

This part of ISO 10303 specifies the application module Manifold surface. 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 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.

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;
• non-manifolds.
