STEP Core Interface
Read and write data in STEP AP214 and STEP AP203 formats
CATIA STEP Core Interface helps users working in a heterogeneous CAD/CAM environment to exchange data through a neutral format. This utility allows users to interactively read and write data in STEP AP214 and STEP AP203 data formats allowing reliable bi-directional data exchange between dissimilar systems. To facilitate access to data, CATIA V6 offers a homogeneous user interface for all supported formats, using Windows-compliant user interface controls and automatic recognition of the STEP file type.
- Supports for Application Protocol
- Access to STEP files
- Supports of geometry and assembly structure
- Transfer quality
- High data transfer performance
Supports for AP214 and for AP203 including Edition 2The CATIA STEP Core Interface supports both the AP214, and the AP203. Regarding the AP214 (including Edition 2), the Class 1 and 2 are supported: the Class 1 and 2 elements are curves, surfaces, shells and solids. Concerning the AP203(including Edition 2), the Class 2, 3, 4, and 6 are supported: the Class 2 elements are curves and surfaces, the Class 3 elements include curves and associated topology (edges), the Class 4 elements include curves, surfaces, and associated topology (faces) and the Class 6 elements are exact solids.
Supports geometry and assembly structuresThe CATIA STEP Core Interface provides integrated interoperability with STEP data formats through Import, Export. For instance, users can read a STEP file, edit its contents in CATIA V5 workbenches, and save the results directly as a STEP file. The common and intuitive V5 interface make easier the use of STEP files, allowing simple and sure data transfers between systems.
Ensures the transfer quality and reliabilityThe geometry is preserved at a high level (solids, shells). And the geometry is adjusted (without or with controlled deformation) so that it can be used in the best conditions in the CATIA V5 modeler. If the STEP file contains an assembly structure (NAUO entities), then the structure is preserved: a CATProduct document is generated. The AP214 and AP203 Edition 2 mechanism of external references to STEP files is supported, in order to handle large and complex assemblies. Data imported from STEP are created as new references. A time stamp is added to the reference ID. In case of several updates of the STEP files, this mechanism allows to easily retrieve from the database any version of these STEP imports.
High data transfer performanceImport and export Geometric Validation Properties (GVP) embedded in the STEP files ensures users of the quality and the reliability of the data transferred. Indeed, in addition of existing OK/KO transfer information, some specifics properties on solids, products and instance of products, such as center of gravity, volume, or wet surface, can be included in the STEP file. During the import, according to the validation of these properties, a user knows if the data are reliable or if he has to perform some corrections to start with a consistent design (For AP214 and AP203 Edition 2).
Interactive and batch transfersHandle very large STEP files, allows the users to exchange large designs. The translator does quick conversions.
