JT Open TRB Meeting – Hosted by LEGO

By Erwin Argyle

HouseOfBrick.pngThe annual JT Open TRB Meeting was held on November 7, 8. We are grateful to LEGO for being such excellent hosts and accommodating us in their brand new House of Brick attraction and conference centre at their HQ in Billund, Denmark.

LEGOHotel.jpgIt was certainly a LEGO-immersed experience as most of us stayed at the LEGOLAND hotel.

The executive welcomes were given by Christian Wissing Kruse of LEGO who provided a very interesting history of the company and by Tony Bergstroem of Siemens who explained what it means to be our first Chief Digitial Officer for the Nordic countries. Both welcomes referenced JT nicely, setting the scene for what was to follow.

Henrik Nielsen gave an overview of how JT is used at LEGO. He detailed its value in dealing with suppliers as the JT geometry is the same as in NX, yet LEGO can hide the design intent. The PMI and 3d annotation enables LEGO to accurately communicate the work that is required. LEGO has a portal that allows suppliers to go into Teamcenter and order JTs and thereby be somewhat self-sufficient if they want more information. Like most companies, LEGO uses products from multiple vendors and JT provides a means to exchange geometry. This is much better than conversion. He also cited animation, Augmented and Virtual Reality use cases, closing with CAM, First Article Inspection and how JT has largely replaced 2D drawings.

The purpose of this host’s presentation was to challenge to rest of us to see if we were using JT everywhere we could and spark discussions. It was very successful.

A number of attendess provided shorter overviews of their activities…

Fred Eckrich explained how Bosch uses JT for supplier integration and data sharing across the four business sectors, Mobility Solutions, Industrial Technology, Energy and Building Technology and Consumer Goods. He also shared challenges/plans regarding the introduction of Model Based Definition and Extended Product Documentation. In his conclusion he pointed out that JT becoming an ISO had greatly helped its adoption into their IT Engineering vision.

Bernd Feldvoss of Airbus showed examples of success with JT across different programs ranging from design to simulation.

Sato-san from Siemens gave a report on the activities of JT Open Japan. Interest in JT continues to grow. They held 4 large (100+ attendee) user meetings and 2 events in 2017.  The topics included JT with AP242 XML, automotive OEM supplier support and the changing role of JT from “viewing” to “3D exchange”. 

Sebastian Handschuh gave a brief update on JT at Daimler. In two years the number of key suppliers who use JT as their primary data source has increased from 100 to 200. New areas of deployment include additive manufacturing and realistic surface rendering. This is on top of the well-established JT Daimler Supplier Package that Sebastian demonstrated for us.

Senko-san and Higuchi-san covered their use of JT at Honda. As well as providing interoperability across many tools, Honda also use JT for Long Term Data Archiving.

Our first vendor presentation of the day was from David Pickett of ITI. The focus this day was on JT verification using CADIQ. Fukuta-san from Elysium gave the next vendor presentation. His focus also was on model verification. Both ITI and Elysium considered many aspects of the data including degradation, unintentional changes, inconsistent data, assembly structure as well as in-body geometry.

Theorem Solutions, like Elysium and ITI are well known for their translator and healing technology. This time though Steve Bee gave us an update on Augmented and Virtual Reality and the role of JT.

Other groups have added JT to their agenda. Recently there as a JT Day organized by ProSTEP iViP and hosted by Bosch. Sebastian Handschuh provided us with an overview. There is a report of it online at LinkedIn.

There were are a number Siemens people to support this meeting. Andy Swiecki and Manuel Loeffler reported on the JT Open Management Review Board, the community site and our presence on social media. John Juckes and Sarah Yeates provided an update on the JT Open Toolkit (JTTK). Andy Attfield hosted a workshop on JT verification. Mike updated us on JT2Go, JT plus PDF and JT 4 Office.

Mike and Sebastian informed us of their work with ProSTEP to promote consistent JT PMI. JT Open has the action item to take over from Sebastian gathering statistics on PMI usage in the JT user community.

 Significant time was given to AR/VR. Mike demonstrated the JT Unity plugin. He was then joined by Mohsen Rezayat who gave us an overview of R&D in that area.

Doug Wolff provided a perspective from another vendor, Epic Games, giving us an overview of the Unreal engine.

 The presentations are available on the JT Open Member Area. To learn more about the JT Open Program, please click here.

We finished with a tour of the House of Brick. Here are some photos.

Once again thank you LEGO for hosting and thank you Henrik Nielsen for approaching your management at LEGO to make this possible.
