For design, this is interoperability between different design systems (CAD to CAD or CAD to CAE). AP214 is considered an extension of AP203. Textual annotations associated to the geometry. As referenced in the table above, the major CAD software vendors can view, import, and export STEP files. From AP203 (Edition 1), this Edition 2 adds, in a modular way : Already additional definitions are in preparation, in particular to complete the Geometrical Dimensions and Tolerances (GD&T). It's a very modern take on MBD with advanced concepts like tolerancing and measurement features, support for assembly-level PMI, and more. But, generally, AP203 is a "general" STEP format, and AP214 is … The only difference between the two (that I am aware of) is that 203 is a geometry only translation and 214 can include PDM information about the CAD model. Creates a visualization (view) of part geometry, graphical PMI annotations, supplemental geometry, and datum targets that is displayed in a web browser. In this article we will be addressing 203, 214, and 242. In addition, in the automotive industry, the ISO 10303 AP 214 standard (STEP 214) is well adopted. Next page : STEP AP242 protocol >>, Headquarters & Technical Agency The STEP translator imports: STEP files as SOLIDWORKS part or assembly documents. Both standards are widely used in the supply chains of many industrial sectors. Composite structures, electrical harness and piping. AP203 defines the geometry, topology, and configuration management data of solid models for mechanical parts and assemblies. A second edition is under development with new geometric capabilities and additive manufacturing setup information. For import, Conformance Classes 1, 2 (surface data only), 4, 5, and 6 of AP203 are supported. I did find this snippet: AP203 originated in the US aerospace and automotive sectors, whereas the AP214 standard has been primarily developed specifically by the German and US automotive industries. STEP configuration data. If I have understood things correctly ap 242 would hold also material information and other manufacturing information that could be read also with ERP or such to recognize and handle the archived files better … As a notice, the works on PDM data, which have defined STEP PDM Schema, have been integrated into these protocols as into others. Tessellation: allowing STEP to support light visualization model. STEP configuration data. What is a STEP file? STEP Application Protocol AP203 is supported for both import and export. Completions to PMI including surface conditions, PMI in assembly and machining features. Difference between STEP AP203 and STEP AP214. The first edition,ISO 10303-21:1994, had some bugs, which were corrected by a Technical Corrigendum. 區別是：step ap203 標準不具有任何顏色，ap214標準具有顏色的。 所以大家看懂了嗎？ 其實也很簡單，大家做非標機械行業的轉換成AP203即可，從事高級曲面或者汽車行業的設計師轉換為AP214更好一點。 However, because MBD CAD files are still in the early adoption phase, it depends on your current software & version having support for it. GD&T with graphical presentations. However, it does not contain PMI. Great for graphical representation. this configuration option is available as the step export format 3d data exchange setting in the creo parametric options dialog box. AP203 defines the geometry, topology, and configuration management data of solid models for mechanical parts and assemblies. Body geometry, body, face, and curve colors, and topology information from an AP214 STEP file. What is PMI (Product Manufacturing Information)? AP 214 is used primarily in the automotive industry. Best STEP File to Use: AP203 vs AP214 vs AP242. AP214 defines everything in AP203 plus colors, layers, GD&T (geometric dimensioning and tolerance) and design intent. The STEP protocols AP203 and AP214 are the mostly used ones in the domain of 3D CAD : AP203 - Configuration Control Design - applies to Mechanical CAD in general, AP214 - Core Data for Automotive Mechanical Design Process - is more focused on Automotive Industry. It is the the go-to STEP file moving forward for 3D CAD-based applications. This file type does not manage Colors and Layers. This initiative has defined a new protocol : AP242, "Managed Model Based 3D Engineering" , harmonized with AP203, AP214 and other widely used STEP protocols. AP242 is the choice for CAD import/export. F-69007 Lyon The STEP protocols AP203 and AP214 are the mostly used ones in the domain of 3D CAD : However the really addressed scope of AP214 in mechanical CAD is roughly equivalent to AP203, overall after the last update of AP203, known as Edition 2 (AP203E2). For example, AP203, AP214, AP238, and AP242 use the same definitions for three dimensional geometry, assembly data and basic product information. If a user is using Solidworks than STEP AP203 file type will define geometry, configuration management data and topology information for parts and assemblies, this file type will not retain color and layer properties. Data related to documentation of design change process, approval, security classification. References to product data represented in another format than STEP. The second edition, ISO 10303-21:2002, included the corrigendum and extensions for several data sections. The STEP translator imports: STEP files as SOLIDWORKS part or assembly documents. STEPファイルの「AP203」と「AP214」の違いについて。実用的な違いは、AP214→カラー情報アリ。AP203→カラー情報ナシ。 Data related to particular technologies such as pneumatic, hydraulic, electric, or electronic. Body geometry, body, face, and curve colors, and topology information from an AP214 STEP file. The following table describes the conformance classes that the interface for STEP supports during import or export. Wireframe geometry from STEP AP203 and AP214 files. In regard of this scope, limitations apply. Application protocol: Configuration controlled 3d design of mechanical parts and assemblies. The STEP translator imports: STEP files as SOLIDWORKS part or assembly documents. AP214 has everything a AP203 file includes, but adds colors, layers, geometric dimensioning and tolerance, and design intent.
