  • STEP

    STEP is the most popular neutral format used to exchange data between CAD systems. STEP (STandard for the Exchange of Product model data) is an ISO standard (iso 10303) to represent 3D objects and related information. The development of STEP started in 1984 as a successor of IGES, SET and VDA-FS. The initial plan was to get a single edition but because of the complexity, the standard had to be broken into separate parts (APxxx). Today AP203 is still one of the most important parts of STEP and is supported by many CAD systems for import and export.

    In a second phase the capabilities of STEP got widely extended, primarily for the design of products in the aerospace, automotive, electrical, electronic, and other industries. This phase ended in 2002 with the second major release, including the STEP parts AP 202, AP 209, AP 210, AP 212, AP 214, AP 224, AP 225, AP 227, AP 232.

    In mid 2010 the development of the new major AP 242 was initiated. This edition will replace the most successful STEP AP203, AP214 and other APs in the mechanical design area. In particular it will contain major updates in the area of Geometric dimensioning and tolerancing, Kinematics, and Tessellation.

    Catia V4 supported native or neutral formats are IGES, DXF, STEP, STL.

    Dassault Systèmes provides utilities to convert CATIA V4 data files so they are accessible to CATIA V5 and CATIA V6. Still, cases show that there can be issues in the data conversion from CATIA V4 to V5 from either differences in the geometric kernel between CATIA V4 and CATIA V5 or by the modelling methods employed by end users. The percentage loss can be minimized by using the appropriate pre-conversion clean-up, choosing the appropriate conversion options, and clean-up activities after conversion.

    For exemple, conversion from CATIA Version 4 to Version 5 created construction problems for the Airbus A380 aircraft. These problems resulted in $6.1B of additional costs due to years of project delays when aircraft wiring was too short to make connections.

    Recommended format for CAD exchange

    Based on our over 25 years experience, CAD Interop recommends below the most relevant CAD formats to convert your data between major CAD systems. To date, the most common exchange format is the STEP format, the most complete and available for the majority of CAD software. But, when possible, it is preferable to use the geometry kernel of the software (such as Parasolid for NX, SolidWorks or Solid Edge) which will allow to read the geometry without translation. If you want to provide read-only access to your CAD data for users who do not have a viewer or other CAD software, we recommend using the 3D PDF format in its faceted (lighter) version.
