The Complete VDA-FS to ACIS Conversion Guide

August 05, 2025

General Information

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

Converting and Optimizing VDA-FS Files to ACIS

RapidPipeline can import VDA-FS files, but currently doesn't support exporting to ACIS format yet.

If you specifically need ACIS 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 ACIS 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.

What are VDA-FS and ACIS files commonly used for?

The VDA-FS file is a format mostly used for automotive surface data exchange.
The ACIS file is a format mostly used for 3D geometric modeling kernel.

Limitations of VDA-FS Files to ACIS Conversion Workflow

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

What's the best way to get VDA-FS files into my 3D applications, and are there alternatives to using ACIS?

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 VDA-FS and ACIS 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.
