This collection is a standard for the exchange of product model data (STEP) module and resource library (SMRL). It is intended for those who are considering adopting ISO 10303 modular application protocols, application modules, and resource parts, or systems built on them, for product data representation …
This standard was last reviewed and confirmed in 2023. Therefore this version remains current.
ISO 10303-521:2011 specifies the integrated resource constructs for Manifold subsurface.
The following are within the scope of ISO 10303-521:2011:
- 3D geometry;
- advanced faces;
- connected face sub sets;
- mappings and geometric transformations;
- open shells;
- relationships between domains of topological objects;
- unbounded geometry with associated topological boundaries;
- use of topology to bound geometric entities.
