## What is JT2Go?

JT2Go Web is developed by Siemens Digital Industries Software for viewing 3D JT files on mobile platforms. It allows users to navigate and interrogate engineering or architectural 3D JT models using modern application interface techniques. JT2Go Mobile defines a new paradigm for viewing and manipulating 3D JT files on handheld touch screen devices. 3D JT files can be generated from virtually all the leading CAD/CAM/CAE tools available to industry today. The JT format was defined by Siemens Digital Industry Software. Users of JT data can share experiences by joining the JT Open Program, an industry group formed by Siemens to support and extend JT’s use by industry. The JT file format specification was adopted by ISO as an international standard in 2012 and is available from ISO as IS 14306:2012. The JT file format specification is published free of charge by Siemens PLM and is available from www.jtopen.com.

Standard features include:
- Zoom, Pan, Rotate. Display of PMI, including Model View with filter capability
- Session based cross section and markup features
- Review assembly structure and part properties
- Live camera background feature.
- Includes Five sample JT files of assemblies with PMI

Note: JT files larger than 20Mgb will affect performance.

### 1/5 — Laden von größeren Dateien funktioniert gar nicht.

*2025-01-03, version 7.0.0*

Leider kann ich nur die Beispieldateien laden. Bei allen anderen Dateien kommt ein Fehlermeldung.

### 1/5 — Die App ist….

*2024-02-01, version 7.0.0*

…eine Zumutung. 
Geht nix. 
Und vor allem SIEMENS interessiert das nicht. 
1.5 Sterne Bewertung seid 7 Jahren. Warum fixen? Lassen wir die App wie Müll einfach auf dem Boden liegen 😂 👍

### 5/5 — Version 14.0 require

*2023-11-16, version 7.0.0*

I need version higher 14.xx 😊

Thanks

### 1/5 — Worthless

*2021-04-14*

All I can do is look at the sample files.  Worthless app.

### 2/5 — No results plot from FEMAP

*2021-02-23*

Doesn’t seem to support the colour contour feature when exported from FEMAP.

### 1/5 — Can not load file lager than 30MB.

*2020-02-23, version 5.0.1*

Pls update to support lager file and scale screen for iPad Pro 11. 
Thanks

### 1/5 — App and IOS 13

*2019-11-19, version 5.0.0*

Unfortunately the App cannot load JT parts from email since IOS 13.

### 1/5 — LATEST RELEASE ISSUE!

*2019-11-18*

Ever since the latest IPhone update I can’t open JT files with this APP. There is no option to use JT2GO to open JT files?  What the heck

**Developer response:** Users with MobileIron installed should be aware of a known issue related to email attachments. MobileIron can be configured to restrict data access. If you are not able to launch JT2Go from JT email attachments contact your MobileIron administrator.

### 1/5 — Was soll das? Es können keine Daten importiert/ geladen werden!

*2019-10-26, version 5.0.0*

Früher konnte man sich einen JT-File per Mail schicken und dann öffnen. Das geht jetzt seit geraumer Zeit nicht mehr. Die App ist damit sinnlos und vollkommen unbrauchbar.
@Siemens: Eine Firma, die sich in der Welt der Digitalisierung beweisen will, schafft es über Jahre nicht, diese App zu aktualisieren! Regiert dort das Krämerseelendenken oder ist diese Fa. einfach zu doof dazu? Auf jeden Fall ist das extrem peinlich!!! ... so wird das nichts Herr Neike :-(

### 1/5 — Half-baked like most Siemens offerings

*2018-02-03*

No clue how to open a file. Tapping the load button takes user to some inbox. How do I get files to this inbox? Instructions on website are worthless.
