General Information

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

Converting and Optimizing IGES Files to JT

There are various ways to convert between IGES and JT. With RapidPipeline, you can easily convert and and optimize IGES files, at scale. It supports JT, as well as many other file formats (examples: FBX, glTF, OBJ, PLY, STL, USD, USDZ, VRM), at high quality.

Below you can find a video explaining how to convert your files:

What are IGES and JT files commonly used for?

The IGES file is a format mostly used for CAD data exchange and interoperability.
The JT file is a format mostly used for lightweight 3D visualization and collaboration.

Limitations of IGES Files to JT Conversion Workflow

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

What's the best way to get IGES files into my 3D applications, and are there alternatives to using JT?

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 IGES 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.
