The Complete STEP to VDA-FS Conversion Guide.

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

There are various ways to convert between STEP and VDA-FS. With RapidPipeline, you can easily convert and and optimize STEP files, at scale. It supports VDA-FS, 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:

The STEP file is a format mostly used for exchange of CAD data.
The VDA-FS file is a format mostly used for automotive surface data exchange.

The following limitations should be taken into account when converting STEP files to VDA-FS format:

STEP Feature (not supported by VDA-FS)	Limitation Details
Materials	Materials Support: STEP: Partial support | VDA-FS: No support Impact: Materials are a fundamental concept in 3D modeling, enabling colored and - in many cases - photorealistic rendering of the 3D model that they are applied to. There are also some formats that don't make use of 3D materials, for example because they need to solely describe a shape (e.g., for many cases in additive manufacturing). In this example, photorealistic PBR materials are used to equip the 3D model with a realistic look. Without support for materials, the model will have to be rendered with a default material (often a default shade of gray).
Scene Nodes	Scene Nodes Support: STEP: Full support | VDA-FS: Partial support VDA-FS Notes: Basic surface organization and grouping Impact: Scene nodes make it possible to address parts of a 3D model separately. For example, a part could be dynamically hidden or shown as part of a 3D configurator. Without support for this feature, a 3D scene will only consist of a flat model, without parts being individually configurable.
Hierarchical Scene Graph	Hierarchical Scene Graph Support: STEP: Full support | VDA-FS: Partial support VDA-FS Notes: Limited hierarchical surface relationships 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.

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 VDA-FS 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.
