However, because MBD/MBE workflows are still in the early adoption phase, AP 203/214 continue to be popular for model geometry. The ISO/TC 184/SC 4 (the STEP governing committee) has withdrawn from doing future work with AP 203 and AP 214. Because it is future proof for MBD/MBE workflows, it's the preferred format. STEP AP 242 is the better format, because it combines both AP 203 and AP 214. STEP AP 203 vs 214 vs 242: Which is the best? Access and digital rights management (DRM).3D parametric/geometric constraints design.References to product data represented in another format than STEP.Īpplication protocol: Managed model-based 3D engineering.ĪP 242 merges STEP AP 203 and AP 214 to create a single standard for model-based 3D engineering.Validation properties: Global, as volume area, center and Local as Clouds of Points.Textual annotations associated to the geometry.Primarily supported by the automotive industry.

Various workflows are now able to come from a single source of truth.įor design, this is interoperability between different design systems (CAD to CAD or CAD to CAE).įor manufacturing, this is the transmission of product definition into manufacturing/measurement software (CAD to CAM or CAD to CMM).

STEP AP 242 also includes PMI ( product manufacturing information) such as GD&T, BOM, and other meta-notes & notes for building and measuring the part or assembly. More importantly, as companies move towards model-based definition and away from traditional paper-based workflows, STEP, specifically AP 242, has been the most popular file format for CAD interoperability downstream with departments, suppliers, subcontractors, and customers. Native CAD file formats from CAD software like CATIA and SolidWorks are proprietary and cannot directly be translated nor converted to another proprietary CAD system.īy exporting into a neutral CAD format like STEP, it allows for interoperability downstream. In this article we address AP 203, AP 214, and AP 242 pertaining to mechanical CAD design, 3D dimensional geometry, and product information. It is detailed into numerous Application Protocols (APs).

STEP is an ISO-standard ( ISO 10303-242:2020) written using the EXPRESS modeling language. STEP (Standard for the Exchange of Product Data) is a popular neutral 3D CAD file format that is interoperable among various CAD programs such as CATIA, Creo, SolidWorks, NX, Inventor, and others.
