Application module: Non manifold surface

1 Scope

This part of ISO 10303 specifies the application module Non manifold surface. The following are within the scope of this part of ISO 10303:

• items within the scope of application interpreted construct "Non-manifold surface", ISO 10303-508:
  • 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 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.
• items within the scope of application module Elemental geometric shape, ISO/TS 10303-1004.
