5 Keywords & Usage : DIESAR Direction Internationale de l Evaluation, AFNeT de la Standardization Sécurité et des Affaires Days Réglementaires Industry needs in visualization of 3D Data Analysis More explicit & easy to understand information Sharing Information Inside the company improve the dialogue between services Improve quality of the technical documentation Simulation Communication Reduce design costs by using more frequently cheaper simulations Use new technologies to improve recognition as a dynamic company New capabilities in process simulation & mechanism simulation Give a quicker access to realistic visualization of the product for marketing : reduce time to market New Technologies 5

6 The dilemma: DIESAR Direction Internationale de l Evaluation, AFNeT de la Standardization Sécurité et des Affaires Days Réglementaires 3D Visualization Data Main Constraints Most of the user do not want to manage multiple representation of the same model (multiple file or format) Complexity of data management Risk of inconsistency between the different representation (are all of them up to date?) Most of the user would like to give access only to the strictly necessary information not more, not less Needs of light package for manipulation and exchange IP protection Usual questions: Usage? (VR, DMU analysis, technical doc ) Security Level? Level of education of the target user? Level of performance of the target IT environment? Time to have access to the complete information? 6

7 Why Using Standards? Easy to use, easy to share, reliable Durability : the format will not completely change next year Security : the definition is public data is independent of a third party technology 1 Format for many tools If not already available : can take a long time to get what s you need standardization is a long process Difference of implementation - same format should give same results but it s not always the case Adoption by software vendors Need to pay attention of the standard s scope There are multiple standards that can be used for a specific needs Standard is a tool not a solution : needs to have a plan and to define a suitable process 7

8 Why Using Standards? All kind of 3D Data can be use for visualization BREP, Tessellation, Many Standard Formats Available : STEP, PDF, JT, X3D, VRML IN THIS PRESENTATION WE WILL CONSIDER LIGHTWEIGHT VISUALIZATION ONLY 8

9 Use Case 1 : Context Short Description Domain Status Usage Security Level Target Users Target IT Environment Time To Access Information Easy access to 3D technical data including PMI & annotation to maintenance service of the end user Aerospace In production Technical documentation for maintenance services IP protection requested Data needs to be simplified and precise definition has to be removed. All kind of users The document should be displayed on very low performance machine. Installation of dedicated software forbidden. Less than 1 hour after customer request 9

10 Use Case 1 : Solutions STEP AP 242 Files (LTAR) Convert BREP to Tessellated data Remove unnecessary details Reduce number of triangles Simplified 3D-PDF Files 10

11 Use Case 1 : Solutions Output target format 3D-PDF : Acrobat reader is available on many machine format is light Nearly anybody knows PDF Simplification of the original data is necessary : Make the data lighter for low performance machine Remove most important information (IP protection) On the fly generation of output data : Avoid to maintain a data base of results Output always up to date 11

12 Use Case 2 : Context Short Description Domain Status Multi-usage of simplified visualization models in a PLM environment. Construction Trucks and Machine In production Usages Quick visualization of a sub-component DMU, collision. Illustration in the technical Documentation Realistic display for marketing Security Level Target Users Target IT Environment Time To Access Information Medium main purpose is to obtain lighter models Multiple internal services : documentation engineers, marketing. Designer or PAO machines Immediate 12

13 Use Case 2 : Solutions PLM Native Data Simplify Exact Data Merge all parts in subassembly Simplified JT Files 13

14 Use Case 2 : Solutions 14

15 Use Case 2 : Solutions Make it Visual BoM & design data are managed in one integrated solution Design artifacts are change controlled & integrated to the BoM, forming a Bill of Information Visual Reporting facilitates improved decision making Collaboration across extended enterprise is supported with appropriate information access Design geometry is easily shared across the extended enterprise Make Value Flow Downstream flow of product & process data enable success of Manufacturing and Product Support Sales & Marketing strategy linked to product Bill of Information On the fly re-generation : As data are store in the PLM, we can easily determine if simplified data is up to date and regenerate it if need. 15

16 Use Case 3 : Context Short Description Domain Status Usage Security Level Target Users Target IT Environment Time To Access Information Management and Control of Archive Data including Composite and PMI & Annotations Aerospace In progress Analysis : Reviewing Archive Data High Experienced Engineer Mechanical Design Workstation Immediate 16

17 Use Case 3 : Solutions Full STEP 242 ready to archive Convert into STEP AP 242 with all information (composite, PMI & GVP) Native Data Validation Archived STEP 242 with GVP Archive Repository For review usage, convert to visualization only STEP file with Annotations & GVP Visualizati on STEP 242 with GVP Review with STEP Viewer 17

18 Use Case 3 : Solutions Output target format STEP AP 242 : Perfect for LTAR (GVP) As light as other lightweight formats if compressed Examples for these GVP are: Assembly, e.g. number of children and solid centroids PMI, e.g. polyline curve length comparison Tessellation, e.g. centroid and surface area Composites, e.g. number of sequences and cut pieces 18

19 CONCLUSIONS ON THE LIGHTWEIGHT VISUALIZATION STANDARDS : From our experience, one file/format for all needs is a myth A good practice is more a question of process than format or tools Standards are good solutions for long term processes Standards formats are structuring ON THE VISUALIZATION PROCESSES : Simplification is the key Need to protect IP is strong Thanks to the increase of performance, we want now to display everything, BUT : this is still too much for most of the machines. 19
