Convert VDA to XML

Understanding VDA and XML file formats

VDA (Verband der Automobilindustrie) is a file format primarily used for the exchange of 2D and 3D CAD data, especially in the automotive industry. It is a neutral format that allows interoperability between different CAD systems. The most common VDA format is VDA-FS (VDA-FLÄCHEN), which is used for surface geometry data.

XML (eXtensible Markup Language) is a flexible, text-based format used for storing and transporting structured data. XML is widely used for data exchange between different systems and platforms due to its readability and compatibility.

Why convert VDA to XML?

Converting VDA files to XML format is useful when you need to integrate CAD data into applications that require structured, readable data, or when you want to automate data processing and exchange between different software systems.

How to convert VDA to XML

Direct conversion from VDA to XML is not always straightforward, as VDA is a geometry-based format and XML is a data structure format. The process typically involves:

1. Importing the VDA file into a CAD or data conversion tool.
2. Exporting or saving the data in XML format, often after mapping the geometry or attributes to an XML schema.

Recommended software for VDA to XML conversion

Okino PolyTrans and Datakit CrossManager are two professional tools that support VDA file import and can export to XML or intermediary formats that can be further converted to XML. For custom workflows, you can use Open CASCADE (an open-source CAD kernel) to parse VDA files and write scripts to export the data as XML.

Typical steps using Datakit CrossManager:

• Open CrossManager.
• Use File → Open to select your VDA file.
• Choose XML as the output format.
• Click Convert to start the process.

Tips for successful conversion

• Ensure your VDA file is not corrupted and is compatible with the chosen software.
• Check if the XML output meets your schema or application requirements.
• For complex conversions, consider custom scripting or consulting with a CAD data specialist.
