The following settings are recommended up to CATIA V4.2.5 with COM/STEP 184.108.40.206 and CATIA V5R24 (Dassault).
- No elements should be placed in NOSHOW/NOPICK.
- Model should be cleaned of all unused information, because the translator exports the complete content of CATIA-parts.
- Unused DETAILS (in all workspaces)
- Unused elements from NOSHOW (in all workspaces)
- Update SOLID-M into SOLID-E with CATSOE utility.
- Perform SOLIDE/UPDATE, also if message UPDATE ALREADY DONE appears. (Regeneration removes inconsistencies.)
- Generate Volumes from SOLID-E and delete SOLID-E in all workspaces. (Geometry is still exported as a solid in STEP.)
- Scaled and mirrored dittos (EXPLODE function) should not be used.
- Before export elements of special CATIA modules (e.g. PIPING, BUILDING DESIGN) need to be converted to STEP conform elements.
- Use CATCLN.
- Assembly structures in SETs should be transferred to DETAILS.
- Link all SETs if possible (SETS -> LINK).
- Solids/Volumes consisting of separate Bodies should be avoided.
- Objects used for Boolean operations should show good penetration.
CATIA V4 (T-Systems) - STEP Preprocessor
- The COM/STEP STEP Processor can be used in batch, interactive and Java mode. The following descriptions refer to the Java GUI.
- Menu STEP:
- Select AP214 Version IS
- Conformance Class: CC2 for geometry and CC20 for drawings
- Select Product Structure S3: Item_Definition_Structure for assemblies
- Geometry and topology: select G2, G3 and G5, do not select G4 and G7
- Menu Conversions
- Choose Solid as Target modeling system.
- INDEX and DATA size should always be set to generous values (50000, 200000).
- Exporting DETAIL/DITTO creates STEP assemblies with the top level product named after the CATIA model.
- No adjustment is necessary.
CATIA V5 (Dassault) - STEP Postprocessor
- To import a STEP File please choose File -> Open... and select STEP file.
- Recommended settings in the STEP import options (Tools -> Options... -> Compatibility) :
- It is recommended to set the Continuity Optimization for Curves and Surfaces for the C2 continuity on Automatic Optimization.
- STEP Assemblies created with the MAPPED_ITEM approach are not supported yet by the CATIA V5 translator.
- The import logfiles "filename.rpt" and "filename.err" gives further information.
- Validation properties are supported.
CATIA V5 (Dassault) – System
- Shaded view is helpful and gives a first impression of the model quality.
- Open.bodies are an indication of faces failures after the import of solids.
- The filename of the imported model must not have special characters.
