Converting and Optimizing Parasolid Files to VDA-FS
There are various ways to convert between Parasolid and VDA-FS. With RapidPipeline, you can easily convert and and optimize Parasolid 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:

Limitations of Parasolid Files to VDA-FS Conversion Workflow
The following limitations should be taken into account when converting Parasolid files to VDA-FS format:
| Parasolid Feature (not supported by VDA-FS) | Limitation Details |
|---|---|
| Materials | Materials Support: Parasolid: Partial support | VDA-FS: No support   Parasolid Notes: Basic material properties for modeling and analysis 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: Parasolid: 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: Parasolid: 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. |
| Scene Composition | Scene Composition Support: Parasolid: Full support | VDA-FS: Partial support   VDA-FS Notes: Simple surface assembly organization Impact: Scene Composition describes the process of composing a scene through links from a main scene that pull in various other scenes/3D models. This can also happen in a nested fashion (through multiple levels of linkage). With a target format not supporting this feature, references to external models must be resolved and the content be baked into one 3D model, which is then saved in that target format. |
| Standardized Format | Standardized Format Support: Parasolid: Full support | VDA-FS: Partial support   VDA-FS Notes: Industry-specific format with limited adoption outside automotive Impact: Standardization plays a huge role in 3D model formats. With a format being standardized, every application will have a clear way of how to load or store data using this format. This makes it easier to re-use the 3D model across different applications, but also to make sure it will still be accessible and usable after a couple of years. |
What's the best way to get Parasolid files into my 3D applications, and are there alternatives to using VDA-FS?
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 Parasolid 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. 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.
