The Complete DGN to JT Conversion Guide

This guide is part of the RapidPipeline 3D Formats Knowledge Database. It shows how to convert DGN to JT, if you'd like to know more about the formats, please check out the following links:

RapidPipeline can import DGN files, but currently doesn't support exporting to JT format yet.

If you specifically need JT 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 JT 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.

The DGN file is a format mostly used for CAD and infrastructure design data.
The JT file is a format mostly used for lightweight 3D visualization and collaboration.

The following limitations should be taken into account when converting DGN files to JT format:

DGN Feature (not supported by JT)	Limitation Details
Texture Transforms	Texture Transforms Support: DGN: Full support | JT: Partial support JT Notes: Basic texture transformation support Impact: Texture transforms describe transformation operations that are applied to 2D texture images or UV coordinates when using 2D texture data on a 3D surface. They can be used, for example, to make sure that material patterns are using real-world scale when rendered on the 3D surface. In this example, such a pattern is used and scaled with the help of a texture transform. Without support for this feature, the texture pattern shows up at the wrong scale.
PBR Materials	PBR Materials Support: DGN: Partial support | JT: No support DGN Notes: Limited PBR support in newer versions Impact: PBR materials enable Physically-Based-Rendering (PBR) for a standardized, photorealistic look of rendered images. PBR uses concepts like metallic-roughness or specular-glossiness properties and a microfacet-based modeling of the surface, using a concept called BRDF (Bi-Directional Reflectance Distribution Function). In this example, PBR materials are used to achieve realistic looking plastic and metal materials. Without support for PBR materials, only basic colors and shading can be used (for example, based on more simple shading models, such as the Blinn/Phong model).

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 DGN and JT 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.
