Visualization framework based on ISO 10303 – STEP standards linking product definition, management and visualization in the value chain Jean Brangé : Jean. brange@boost-conseil. com Project leader STEP AP 242 ed 2 May 15, 2017 STEP and visualization @ SC 4

Would we dare to define 3 D visualization ? objects 3 D visualization as the visual presentation on a entertain screen or another media of graphical and textual 3 dimensional representations of a set of data representing objects, information or results of a learn information computational process in order to: • facilitate capture of the understanding of the object, for visual information sharing with users • and sometimes to promote decision process by a human looking at the data visualized in a compare understand decide medium May 15, 2017 STEP and visualization @ SC 4 view

Visualization in the STEP Framework STEP provides a data model which integrates the whole data landscape for the product development, manufacturing operations and maintenance. The concept of multiple representations of the product, including multiple geometrical representations allows us to define an optimized visualization model with links to the rest of the data model. The model based STEP framework allow us to ensure consistency of the integrated information model and the corresponding implementation forms.

Analysis • Promoting the re-use of the rich integrated STEP data model in the enterprise processes has great value • There is a confirmed opportunity for industry to have a structured approach on 3 D product visualisation and to enable integration of product data in visualization application across the life cycle of the product in all the activities of the enterprise. • Use cases exist related with the visualization of product data other that geometry (meta data, production data, financial data. . . ) • Need for STEP interfaces for geometry and other STEP data access (OSLC ? MOSSEC approach? ) • There is also a need for a simple STEP geometry schema and associated API , with and without PMI (integration with STEP New Architecture ? ) Requirements to STEP AP 242 geometry conformance classes using the STEP New Architecture May 15, 2017 STEP and visualization @ SC 4

Objective • Publish a reference architecture for product data visualization Objectives & Next steps • There a number of proposed New Work Items and tasks related to 3 D visualization and other forms of consumption of product data. These New Work Items have been raised within SC 4 and also other subcommittees. It is therefore proposed to create a new WG which may be joint with JTC 1/SC 24 and TC 171/SC 2 to undertake these work items. • In Oslo in May 2017, the ISO/TC 184/SC 4 requests its Secretariat to create the WG 16 with the following title and scope • Title: Formats for 3 D Visualization and consumption of product data • Scope: • Develop and maintain standards for 3 D visualization of product models, including geometry, product structure and other classes of information. • Develop and maintain standards for consumption of data derived from product models. • Develop and maintain standards for interfaces from SC 4 product definition standards. • Establish liaison with other standards activities working on information models for 3 D visualization. • SC 4 requests its Secretariat to assign any NP within scope to WG 16.

STEP had Product Data Exchange in its genes IS 0 10303 is an International Standard for the computer-interpretable representation and exchange of product data. The objective is to provide a mechanism that is capable of describing product data throughout the life cycle of a product, independent from any particular system. The nature of this description makes it suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases and archiving.

Collaboration processes are defined in order to allow organization to collaborate while still keeping their own internal optimized processes. The collaboration processes take advantage of the STEP standard. Until now, the management and decision processes were not the target of STEP.
