General Information
This guide is part of the RapidPipeline 3D Formats Knowledge Database. It shows how to convert JT to CATIA, if you'd like to know more about the formats, please check out the following links:
Converting and Optimizing JT Files to CATIA
RapidPipeline can import JT files, but currently doesn't support exporting to CATIA format yet.
If you specifically need CATIA export functionality for your workflow, please feel free to get in touch with us - we'd be happy to discuss your requirements and potential timeline for adding this export capability.
If you need, you can import CATIA files and convert them to any of these 8 formats: FBX, glTF, OBJ, PLY, STL, USD, USDZ, and VRM.
In the meantime, you can explore other options on the 3D Formats Knowledge Database, which might serve as suitable alternatives for your workflow depending on your target applications and use cases.

Limitations of JT Files to CATIA Conversion Workflow
The following limitations should be taken into account when converting JT files to CATIA format:
| JT Feature (not supported by CATIA) | Limitation Details |
|---|---|
| Geometry Compression | Geometry Compression Support: JT: Full support | CATIA: Partial support   CATIA Notes: CATIA supports various compression techniques for geometry data, particularly in the 3DXML format, though not as extensively as dedicated compression formats. Impact: Geometry compression describes the process of compressing the representations of a 3D model's geometry, usually a triangle mesh. 3D geometry compression does not change the topology of a 3D model, but just changes the way that a 3D model and its 3D positions and related vertex data is stored. Geometry compression can be lossy (just like JPEG compression in image processing can be lossy, for example), in which case one might notice slight artifacts like variations in 3D vertex positions (compared to the uncompressed 3D model). However, such differences are often not noticeable. There are only very few standards for geometry compression, like glTF's support of Draco compression and similar extensions. |
| Standardized Format | Standardized Format Support: JT: Full support | CATIA: Partial support   CATIA Notes: While CATIA files are proprietary, the software supports many industry standards and has openly published the 3DXML format specification. Impact: Standardization plays a huge role in 3D model formats. With a format being standardized, every application will have a clear way of how to load or store data using this format. This makes it easier to re-use the 3D model across different applications, but also to make sure it will still be accessible and usable after a couple of years. |
What's the best way to get JT files into my 3D applications, and are there alternatives to using CATIA?
Doing 3D conversion right, especially at scale, can be tricky, as 3D data is in general a rather complex (yet very powerful!) medium. This also applies to JT and CATIA files - the conversion guide above provides a rough first idea about that. Once you know what you would like to do, tools like RapidPipeline can help you perform the necessary steps, and to even automate the process for thousands or even millions of files.
Especially when introducing pipelines and workflows at scale in an enterprise context, it is usually good to rely on dedicated tools and expertise, making sure you do not introduce any steps into your 3D workflow that are detrimental to the final output's quality, or that take your team too much time (and money).
If you're interested to hire dedicated expertise from the best in the field to help your company reach your goals fast and reliably, please do not hestitate to contact DGG. Being the creators of RapidPipeline, and ambassadors for open 3D standards for more than a decade, we have been building some of the world's most advanced 3D pipelines, having processed many millions of 3D assets.
Therefore, our expertise will help you to reach your goals faster, at scale, and with the least possible friction, since we are focused on maximum interoperability.
