Did someone say JT?

JT logo file format

The Siemens JT (Jupiter Tessellation) format has been on the rise for years now, and to be exact, since the ISO approved it as an international 3D model visualization format back in 2012!

This format is the best when looking to have a holistic approach to a manufacturing project. Simply because JT extension is used in product lifecycle management (PLM) systems. So, all actors in the production cycle can easily communicate when they design, analyze, optimize and produce a product.

As you can see this format is ideal for manufacturing companies, and is widely used in the automotive industry as it helps them extract 3D data from a PLM solution and make unified decisions about production.

A popular format

For those who aren’t familiar with the JT format, here are three reasons why it’s so appreciated:

  • Easy to exchange

Even when using different CAD systems, internal teams, suppliers and subcontractors can freely transfer a JT file. That makes collaboration possible and therefore decisions can be rapidly taken in the development process, avoiding mistakes along the way.

  • Long term data retention

It is easy to store because it’s a lightweight and well documented 3D data format that allows industries to store and exchange their 3D models whenever they need to.

  • Last but not least, Full data preservation

The JT format is the gold standard in maintaining the original file data: product structure, metadata, 3D geometry data, Product Manufacturing Information (PMI), Levels of Details and many more.

In short: you love it, and so do we.

Fast forward to 2020, we looked at ways to enhance the import of the extension in our software

… but what does this mean?

Pixyz 2020.2 & JT format

If you are an engineer who seeks to minimize the complexity of your 3D products designs, let’s say to work with it in real-time. Well, look no further, Pixyz helps you to develop optimization process according to specific metadata/model or simple review them quickly.

  • Faster and better import:

Why wait? While accessible to all, it usually takes around 1+ hour to import huge assemblies using JT format. Pixyz’s improvements have reduced that time to display your large 3D models in under 5 minutes, if you favor speed.

  • Reading BRep for richer optimization scenarios

You may be less in a hurry and want the best possible results. This is also possible by asking Pixyz to re-build perfectly tessellated models from the CAD data.

We get the Brep definition in the JT files, which allows to produce a lighter mesh and keep the geometry of the mode hanks to the quality of the Pixyz tesselator!

  • More realism:

Why compromise? Our solution used to only read the color material of JT’s format when importing. From now on, you also have the option to preserve the texture material, so the rendering of your scene gains in quality and realism.

  • Flexibility:

We welcome everyone! Would you like to inspect and review an old JT file? Or maybe import the JT v10.3 ? Pixyz makes it possible! All JT versions are supported.

  • Get full PMI Review with high viewer performance

Either import a product line or just a part, you’ll be able to switch from one PMI view to another or to display all of them by keeping your FPS (Frame Per Second) at high level, even with thousand of parts and millions of polygons.

So now, get all the value of your JT files!
