GB/T 16656.509-2010 Industrial automation systems and integration.Product data representation and exchange.Part 509:Application interpreted construct:Manifold surface (English Version)
This part of GB/T 16656 specifies the interpretation of integrated resources to meet the needs of describing geometric shapes by means of manifold surface models. This standard applies to: three-dimensional points; points defined in the parameter space of curves or surfaces; three-dimensional curves; curves defined in the parameter space of surfaces; analytical curves: lines, circles, ellipses, parabolas and hyperbolas; intersecting curves; consisting of at least three Polylines composed of points; Analytical surfaces: plane, cylinder, cone, torus, sphere; Surfaces swept by rotating or linearly stretching curves; Sculpting curves or surfaces; Trimming curves or surfaces with topology entities; Using topology Solids composed of curves or surfaces; Copying curves, surfaces, and surface models; 3D offset curves and surfaces; 2D manifolds. This standard does not apply to: unbounded geometries; self-intersecting geometries; geometries in two-dimensional Cartesian coordinate spaces; replication of points; topologies not associated with corresponding geometric domains; non-manifolds.
