This guide is part of the RapidPipeline 3D Formats Knowledge Database. It shows how to convert STEP to IGES, if you'd like to know more about the formats, please check out the following links:
Converting and Optimizing STEP Files to IGES
There are various ways to convert between STEP and IGES. With RapidPipeline, you can easily convert and and optimize STEP files, at scale. It supports IGES, 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:

Limitations of STEP Files to IGES Conversion Workflow
The following limitations should be taken into account when converting STEP files to IGES format:
| STEP Feature (not supported by IGES) | Limitation Details |
|---|---|
| Hierarchical Scene Graph | Hierarchical Scene Graph Support: STEP: Full support | IGES: Partial support   IGES Notes: Basic entity relationships and grouping Impact: Scene graphs are one of the most common concepts in 3D computer graphics. By structuring the scene in a hierarchical way, logical parts of it can be easily addressed and transformed. This is useful in many applications, like games or 3D configurators. Without support for this feature, a 3D scene cannot be structured hierarchically, for example objects cannot be logically composed of smaller objects. |
What's the best way to get STEP files into my 3D applications, and are there alternatives to using IGES?
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 STEP and IGES 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.
