Most of the user do not want to manage multiple representation of the same model (multiple file or format) Complexity of data managementRisk 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 lessNeeds of light package for manipulation and exchange IP protection
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 ?
3D Visualization Data Main ConstraintsThe dilemma:
Usual questions:

Why Using Standards ?
AFNeT Standardization Days 2017 - ParisApril 19 & 20, 2017
Easy to use, easy to share, reliableDurability : the format will not completely change next year Security : the definition is public – data is independent of a third party technology1 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 scopeThere are multiple standards that can be used for a
specific needsStandard is a tool not a solution : needs to have a
plan and to define a suitable process

Why Using Standards ?
AFNeT Standardization Days 2017 - ParisApril 19 & 20, 2017
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

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

Use Case 1 : Solutions
AFNeT Standardization Days 2017 - ParisApril 19 & 20, 2017
• Convert BREP to Tessellated data
• Remove unnecessary details
• Reduce number of triangles
STEP AP 242 Files

Use Case 1 : Solutions
AFNeT Standardization Days 2017 - ParisApril 19 & 20, 2017
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

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.

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

CONCLUSIONS
AFNeT Standardization Days 2017 - ParisApril 19 & 20, 2017
ON THE LIGHTWEIGHT VISUALIZATION STANDARDS : From our experience, one file/format for all needs is a mythA 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 keyNeed 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.
